SINOCONVE BJ Type Banded Classical V-Belts for Industrial Power Transmission with Low Elongation

BJ Type Banded Classical V-Belt

BJ is a medium-duty banded classical V-belt featuring a 17 mm rib top width, 19 mm pitch distance, 13 mm height, and 40° belt angle. Its available inside length range is 47-394 inches. Multiple ribs are permanently joined by a durable backing band, allowing the belt set to maintain consistent seating across multi-groove pulleys. The reinforced tensile structure provides low elongation, stable load distribution, and reliable power transmission under fluctuating industrial loads. The joined construction also helps limit belt whip, rib separation, and uneven tracking during start-stop operation. It is suitable for industrial fans, pumps, compressors, machine tools, processing equipment, and agricultural machinery. Maximum joined-rib quantity varies with belt length.

Technical Data

Maximum Band Quantity by Length

Product Advantages

• Low-elongation tensile cords help maintain uniform tension across all BJ ribs
• Joined construction improves tracking on medium-duty multi-groove pulleys
• Stable load distribution supports smooth operation under changing torque
• Reinforced backing reduces belt whip and separation during start-stop cycles
• Good resistance to heat, oil, ozone, abrasion, and repeated flexing

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: BJ 47. The number of joined ribs must be confirmed separately.
