V-Belt
V-Belt: classical and narrow V-belts for reliable friction power transmission.
A GOODLY V-belt is a power-transmission belt with a trapezoidal cross-section that wedges into a matching V-grooved pulley. The wedging action produces high friction with a simple, robust design, which is why the V-belt has driven machinery for over a century. We supply V-belts in classical sections such as Z, A, B, C, D and E, and narrow sections such as SPZ, SPA and SPB, for pumps, compressors, fans, conveyors and general industrial drives.

What Is a V-Belt?
A V-belt is a power-transmission belt with a trapezoidal cross-section that wedges into a matching V-grooved pulley. The wedging action produces high friction with a simple, robust design, which is why the V-belt has driven machinery for over a century. V-belts are supplied in classical sections such as Z, A, B, C, D and E, and narrow sections such as SPZ, SPA and SPB, for pumps, compressors, fans, conveyors and general industrial drives.
Because we manufacture in our own plant, we can advise on the right compound, cord and tooth profile for your machine before you order, and back it up with sample belts for your own testing.
Key Advantages of Our V-Belt
Every belt is engineered, moulded and inspected in house, so the advantages below are backed by real production data rather than marketing language.
Reliable Wedge Grip
The trapezoidal section wedges into the pulley groove for high friction and dependable drive.
Full Section Range
Classical Z/A/B/C/D/E and narrow SPZ/SPA/SPB sections for most industrial drives.
Heat & Oil Resistant
Fiber-reinforced CR and EPDM compounds resist heat ageing, oil and abrasion.
Aramid Cord
High-tensile aramid cord keeps the belt from stretching under load.
Shock Absorbing
Absorbs start-up shock and vibration, protecting bearings and reducing noise.
Made to Length
Moulded and cut to your exact section and length, matched sets available.
Why Buyers Choose GOODLY as Their V-Belt Supplier
GOODLY is a belt manufacturer in Guangzhou, China, not a trading company. We control the compound, the cord, the moulding and the final inspection, which is why our v-belt keeps the same performance from the first sample to the last production batch. Send us a drawing or a used belt and we will match it, improve it if we can, and supply it on a schedule you can plan around.
- V-Belt manufactured in our own Guangzhou factory
- ISO 9001 quality system with records for every batch
- Engineer-to-engineer support from sample to production
- Full material and dimensional reports on request
V-Belt Support from Our Engineering Team
When you buy a v-belt through GOODLY you deal directly with the people who make it. Our technical team works from your drawing, sample or machine details, recommends the compound and tension member, and follows the order through production and testing. This engineer-to-engineer support is the reason most of our customers reorder, and it is available before, during and after every shipment.
- Technical drawings and material reports supplied on request
- Samples produced for machine trials before volume orders
- One point of contact from enquiry to delivery
- Export packing and worldwide shipping handled in house

V-Belt Performance Data
The figures below are typical values from our own testing. Your exact application may need a different combination, so tell us the load, speed and environment and we will confirm.
| Compliance | ISO 4184, DIN 2215, RMA IP-20 |
| Working temperature | -30 °C to +100 °C |
| Oil resistance | Good, with CR and EPDM compounds |
| Elongation | Low under working load |
| Efficiency | High, with stable tension |
| Service life | Long, with heat and abrasion resistance |
V-Belt Materials and Reinforcement
We select the compound and the tension member together, because the material combination is what determines how a v-belt performs over its working life.
CR (Neoprene) Rubber
Good oil, heat and abrasion resistance for general industrial drives.
EPDM Rubber
Excellent heat ageing, ozone and weather resistance for automotive and outdoor duty.
Aramid Cord
High-tensile cord for low stretch and reliable power transmission.
Fabric Wrap
Wrapped or raw-edge construction for grip and quiet running.
Industries That Use Our V-Belt
From food and packaging to printing and automated assembly, the same engineering discipline is applied to every v-belt we ship.
Custom V-Belt Options
Almost every order we make is a variation. Tell us the machine and the product, and we will tailor the v-belt to fit.
Section Selection
Classical or narrow section chosen for the power and pulley size.
Made to Length
Cut and joined to your exact outside length, plain or cogged.
Matched Sets
Matched sets of equal length for multi-belt drives.
Compound Selection
CR or EPDM compounds for oil, heat and weather resistance.
Our 8-Step Quality Control for V-Belt
Each v-belt passes the following checkpoints before it is packed, and the records are kept against your order number.
V-Belt Frequently Asked Questions
Quick answers to the questions our customers ask most often about v-belt.
How do I choose a V-belt section?
The section depends on the power and the pulley diameter. Tell us the drive power, the pulley diameters and the speed, or the belt you are replacing, and we will recommend the correct classical or narrow section.
What is the difference between classical and narrow V-belts?
Classical sections (Z, A, B, C, D, E) suit traditional drives with larger pulleys. Narrow sections (SPZ, SPA, SPB, SPC) carry the same power in a slimmer belt, saving space and weight.
Do you supply matched sets?
Yes. For multi-belt drives we supply matched sets of equal length so the belts share the load evenly.
Can you supply cogged and heat-resistant belts?
Yes. We supply raw-edge cogged belts for small pulleys and CR or EPDM compounds for oil, heat and weather resistance.
How long does production take?
Standard V-belts are typically ready in 7 to 10 working days after we confirm section, length and quantity.
