SINOCONVE CJ Type Banded Classical V-Belts for Heavy Industrial Equipment with Strong Load Capacity

CJ Type Banded Classical V-Belt

CJ is a heavy-duty banded classical V-belt with a 22 mm rib top width, 25.5 mm pitch distance, 17 mm height, and 40° belt angle. Available in 63-551 inch inside lengths, it is designed for high-load multi-groove transmission where separate belts may experience vibration or uneven load sharing. The reinforced top band firmly connects the ribs and provides strong transverse stability, helping maintain pulley engagement during shock loading and continuous duty. High-strength tensile members support strong load capacity and dimensional stability, while the rubber and fabric structure resists heat, oil, ozone, abrasion, and repeated flexing. Typical applications include large compressors, crushers, heavy fans, pumps, processing machinery, and agricultural equipment.

Technical Data

Maximum Band Quantity by Length

Product Advantages

• Heavy-duty joined construction distributes high loads across multiple CJ ribs
• Reinforced top band maintains transverse stability during shock loading
• Accurate 25.5 mm pitch spacing supports reliable multi-groove pulley engagement
• High-strength tensile members resist elongation under continuous torque
• Durable rubber and fabric layers resist heat, oil, ozone, wear, and flex fatigue

Structure

The belt consists of multiple V-shaped ribs, high-strength tensile cords, rubber compression layers, protective fabric, and a reinforced joining band. The backing band controls lateral movement and keeps the ribs aligned while the sidewalls engage the pulley grooves.

Model Naming Rule

Model = production type + inside length in inches. Example: CJ 63. The number of joined ribs must be confirmed separately.
