  • Cogged Raw Edge Design

    Notched sides and bottom improve flexibility, reduce bending stress, and dissipate heat for longer belt life.

  • Heat & Oil Resistant

    EPDM / CR compounds withstand high temperatures and oil exposure in automotive and industrial drives.

  • High-Strength Cord

    Polyester / Aramid tensile cords minimize stretch and maintain stable power transmission.

Typical Applications

Our V-belts deliver dependable friction-drive power transmission across a wide range of industries. From HVAC and agriculture to pumps, fans, compressors, and generators, they offer smooth operation, shock absorption, and cost-effective maintenance.

  • Automotive Engine Drives

    Cogged V-belts drive alternators, water pumps, air conditioning compressors, and cooling fans. Their flexible cogged design reduces heat buildup and improves power transfer on small pulleys.

  • Industrial Compressors & Pumps

    In compressor stations and pumping systems, cogged V-belts handle high torque and continuous operation. The notched design reduces bending stress and extends service life in demanding industrial environments.

  • Agricultural Equipment

    Tractors, harvesters, and irrigation pumps rely on cogged V-belts for reliable power transmission in dusty, outdoor conditions. The belts resist slippage and maintain performance under variable loads.

What is the minimum order quantity (MOQ)?

Our standard MOQ is 50 pieces per size/specification for standard belts. For customized orders with private branding or special packaging, MOQ starts at 1,00 pieces. We also support trial orders for new customers to verify quality.

How do I choose the right belt type and size?

Share your application (engine, compressor, conveyor, etc.), pulley diameter, speed, and load requirements. Our engineers will recommend suitable V-belts, timing belts, ribbed belts, or wrapped belts accordingly, and provide cross-reference support for OEM part numbers.

Which quality standards do your belts meet?

Our belts are manufactured under ISO 9001 quality management and meet international standards such as RMA/MPTA, DIN 7753, and ISO 1813. Material options include chloroprene rubber (CR) and hydrogenated nitrile rubber (HNBR) for high-temperature applications.

How long does sampling and mass production take?

Standard samples are ready within 5-7 working days; custom samples take 7-12 days. Mass production lead time is typically 15-25 working days depending on order quantity and specifications.

What is your warranty and after-sales policy?

We provide a 12-month warranty against manufacturing defects. If any quality issue occurs under normal use, we offer free replacement or refund after verification. Technical support is available throughout the product life cycle.
