Wrapped 5V (15N) narrow V-belt with a 5/8 inch (16 mm) top width for HVAC, pumps, fans and industrial conveyor drives

● What Is a 5V Belt

A narrow-profile V-belt built to deliver exceptional power in a compact footprint — the workhorse of the 3V/5V/8V family.

The 5V belt is a wrapped narrow V-belt with a 5/8 inch (15.9 mm) top width and a 13.5 mm section height. It sits in the middle of the classical narrow V-belt range: smaller than an 8V, larger than a 3V, and that is exactly why it is the section most often specified. Where an 8V would be oversized and a classical B section would need more width, the 5V lands on the right belt for the job.

The capacity comes from the narrow profile itself. A deeper, narrower belt seats into the groove with more sidewall contact per millimetre of belt width, so it develops more grip at the same tension. The published figure is that a 5V transmits 50–100% more power than an ordinary V-belt of the same top width. For a machine designer, that difference is not an academic number — it is the reason a retrofit can keep the same frame, sheaves and bearing arrangement while moving to a more powerful drive.

Our 5V belts are moulded rather than cut, so every belt of the same specification leaves production with an identical length. In a matched multi-belt drive that means every belt carries the same share of load from the first hour. No one belt runs tight and takes the punishment, no flank wears out early, and no unexpected break stops a production line. The belt also has high transverse stiffness, which keeps it from turning over in the groove under heavy load — a particular issue on long-span drives.

Every belt is manufactured to ISO 4184, the international standard covering dimensional tolerances and performance requirements for V-belts. When you specify our 5V belt, you are ordering a part that seats correctly in any ISO 4184-compliant 5V groove and runs to a known length tolerance.

● Materials & Construction

Three layers, each doing one job properly. Built on chloroprene rubber for genuine resistance to oil, heat, ozone and static.

🔧Tension Member

Imported high-tenacity polyester cords give exceptional tensile strength with very low elongation under load, and are chemically bonded into the rubber body so they will not separate after millions of flex cycles.

🏙Body Compound

The compression section is formulated from chloroprene rubber, giving the belt genuine cold and heat resistance, oil and chemical resistance, and anti-static performance for harsh plant environments.

📦Outer Cover

A treated fabric is wrapped around the full belt to protect the sidewalls from abrasion and oil mist, while raising the friction the belt needs in the sheave groove.

● Why Choose Our (15N)5V Wrapped V-Belt

Every claim below is measurable on the drive, not just on a spec sheet.

✔High-Performance Narrow Profile

At 5/8 inch top width and 13.5 mm height, the 5V lets you design a smaller drive system, saving frame space and reducing the overall weight of the machine.

✔High Power Capacity

Transmits 50–100% more power than a conventional V-belt of the same top width. Compact frame, full torque — the reason a 5V is specified for compressors and mills.

✔Stretch-Resistant & Stable

Polyester cords hold their length under maximum tension. Belts do not run slack after break-in, so re-tensioning stays rare and unplanned stops stay off the calendar.

✔Wear-Proof in Daily Service

In continuous running under rated load, measured belt wear stays below 2% even after 1,000 hours on the drive. Fewer changeouts, no production line halted for a belt swap.

✔Slip-Resistant Grip

The wrapped cover and narrow profile keep friction high in the groove. When a load spikes suddenly, the belt stays seated and torque keeps moving to the driven machine.

✔Superior Durability

Resistant to heat, oil and abrasion, the (15N)5V runs safely and stably during high-speed operation and in harsh environments without cord damage or sidewall cracking.

✔Energy Efficient

At 95%+ transmission efficiency, more motor output reaches the driven shaft. Over a belt’s service life that difference shows up on the energy bill.

✔Consistent, Batch After Batch

Moulded to length under ISO 4184, so a replacement ordered six months later drops into the same drive without re-engineering the frame.

✔Low-Maintenance Operation

Set the tension correctly at installation and the belt runs for the duration of its service life with only routine visual inspection.

✔Long-Lifespan Construction

Fatigue resistance rated in the millions of cycles, with crack resistance and ozone resistance built into the compound for reliable indoor and outdoor service.

● Industries & Equipment Served

The 5V is specified across six industries and their auxiliary drives — particularly where the frame is tight and the load is heavy.

Steel & Metallurgy

Drilling machines, sawing machines, plate shears, forming machines, conveyors, crushers, mixers, separators, feeders, belt conveyors, cutting equipment and full auxiliary systems. Continuous heavy load is the condition that separates a durable belt from one that fails early.

Mining & Aggregates

Crushing and conveying lines where shock loads arrive without warning. The wrapped jacket and stable cords keep the belt in service between scheduled changeouts rather than on an emergency call-out.

Construction & Building Materials

Milling-planing machines, mixers and other site equipment. Jobsite debris, dust and long run hours expose a weak belt fast; the 5V is built for all three.

Industrial Ventilation & HVAC

Air handling units, dust extraction fans, industrial ventilation and drying systems. Continuous high-speed running makes belt life a direct maintenance cost.

Agricultural Machinery

Seed drills, rotary tillers, mowers, rice mills, micro-tillers, fertiliser spreaders, paddy de-huskers, grain grading screens, cleaning screens, ditch openers and pruning machines.

Printing

Printing presses and their auxiliary equipment, where smooth, stable running and a compact drive layout protect print quality and machine life.

Grain & Oil Processing

Oil presses and all auxiliary equipment, including conveying, elevating and processing drives running long hours in dusty conditions.

Auxiliary Equipment Across All Sectors

Air compressors, pumps, industrial fans, gear reducers, mixers, blowers, conveyors and pulverizers. If a machine needs to turn reliably for years, the 5V belt is on the bill of materials.

● Reading the 5V Code & Matched Sets

Like all 3V/5V/8V belts, the (15N)5V uses a simple code convention: 5V followed by a number that is the outside circumference in inches. So 5V1000 has an outside circumference of 100 inches — about 2540 mm. The number is not the pitch length; the pitch length is shorter by the profile offset, and that conversion is listed in the downloadable chart below.

For any drive using more than one belt, install a matched set. Because our belts are moulded to a consistent length, every belt in the set carries the same share of load. A common failure pattern is one new belt paired with several worn belts: the new belt runs tight, takes almost all the tension and fails in days. Replacing the full set is always the lower-cost choice over the life of the drive.

If you are unsure of the correct code, send us the centre distance, both sheave diameters and the service factor you want to apply. Our engineering team will return a recommended belt code, normally within one working day. MOQ 20 pcs | Delivery 15–20 days.

● Installation & Maintenance

Correct Installation Procedure

Loosen the driven-unit mounting bolts and reduce the centre distance before fitting the belt. Never lever a belt over a sheave rim — the forced bend will break tension cords at one point along the belt.
Seat the belt in the grooves, then increase the centre distance gradually to apply tension.
Tension to the specified value with a proper tension gauge. Too tight overloads the bearings; too loose causes slip, heat and rapid wear.
Run the drive 15–30 minutes under light load so the belt beds into the grooves, then re-check and adjust tension once.
Check sheave alignment with a straightedge. Misalignment wears one belt sidewall quickly and shortens belt life.

Maintenance Guidelines

Inspect belts every 500 operating hours for glazing, cracking or exposed cords.
Keep sheaves clean and free of oil, grease and embedded debris.
Replace all belts in a matched set together — never replace one belt alone.
Store spares in a cool, dry place away from direct sunlight and ozone sources such as electric motors.

● Troubleshooting Guide

The belt cannot be tensioned

Possible causes: the centre-distance adjustment range is too small; the belt has stretched beyond recovery or the drive frame is undersized and overloaded; the belt length is wrong.
Remedies: re-design the drive with a larger adjustment range; re-calculate the drive data and resize the drive; select the correct 5V length.

The belt wears out too quickly

Possible causes: the belt has exceeded its service life and the compound has aged; the drive imposes excessive tension; poor installation causes misalignment, uneven wear or vibration.
Remedies: replace on a fixed schedule, correct the drive design, and align and seat the belt properly at installation.

The belt breaks after a short time

Possible causes: it was pried onto the sheave and cords were damaged; a foreign object entered the drive and snapped it; the driven system seized; severe shock loading or a load applied too suddenly.
Remedies: loosen the mounting bolts and reduce centre distance to fit the belt with no forced leverage; fit a guard to keep debris out; stop and clear the fault before restarting; re-design for the actual shock load and ramp loads up gradually.

Black powder is coming off the belt

Cause: on a new installation the sheave surface finish is too rough, so the belt rubs off fine black rubber dust.
Remedy: improve the sheave surface finish.

The belt slips

Possible causes: insufficient tension, worn or contaminated sheave grooves, or a drive ratio that no longer matches the requirement.
Remedies: adjust tension to the specified value with a tension gauge; inspect and replace worn or contaminated grooves; correct or replace the drive so the ratio matches.

●Frequently Asked Questions

What is the minimum order quantity for 5V belts?

Our standard MOQ is 20 pieces per size. For mixed-length orders, recurring supply contracts or bonded warehouse programmes, contact our sales team for volume pricing and a flexible MOQ.

What is the delivery lead time?

Standard delivery is 15–20 days from order confirmation, depending on order volume and current production scheduling. Rush orders can be accommodated on request.

Do you support custom belt lengths?

Yes. We supply custom lengths outside the standard range, and we also manufacture banded (joined) V-belts for drives where individual belts can turnover or whip — particularly useful on long-span 5V drives. Provide the required dimension, section and application. Custom items may carry a longer lead time and a minimum quantity.

How do I read the (15N)5V belt code?

The number after 5V is the outside circumference in inches. So 5V1000 has an outside circumference of 100 inches, or about 2540 mm. It is not the pitch length — convert using the chart in the downloadable PDF.

What material is the 5V belt made from?

The 5V body is chloroprene rubber (CR), with a polyester tension cord and a wrapped fabric outer jacket. This gives the belt genuine resistance to oil, heat, ozone and static.

Are your 5V belts ISO certified?

Yes. All our 5V wrapped V-belts are manufactured to ISO 4184, covering dimensional tolerances, length consistency and performance requirements.

Can I replace just one belt in a multi-belt drive?

We recommend replacing the full matched set. A single new belt runs tighter than the worn belts beside it, takes most of the load and fails early. Replacing all belts is cheaper over the drive’s life.

What temperature can the standard 5V belt handle?

The standard chloroprene rubber construction runs reliably from -40°C to +90°C, with resistance to oil, chemical, ozone and static conditions built in.

Do you provide technical support for drive design?

Yes. Our engineering team provides free support for drive calculation, belt selection and tensioning. Send centre distance, sheave diameters and service factor and we respond within one working day.

How do I identify my current 5V belt?

The code is printed or embossed on the belt back, for example 5V1000 for an outside circumference of 100 inches. If the marking has worn away, measure the outside circumference and top width and send both figures to us — we will identify the correct replacement.
