SINOCONVE EJ Type Banded Classical V-Belts for Extra-Heavy Drives with Superior Durability

EJ Type Banded Classical V-Belt

EJ is an extra-heavy banded classical V-belt with a 39 mm rib top width, 44.5 mm pitch distance, 25.5 mm height, and 40° belt angle. Available in 220-630 inch inside lengths, it is designed for large multi-groove systems where stable belt grouping and dependable torque transmission are critical. The integrated backing band keeps all ribs working together and helps reduce turnover, belt whip, and uneven tension under heavy loading. Reinforced tensile members provide dimensional stability and strong resistance to elongation, while the heavy rubber and fabric construction offers superior durability against heat, oil, ozone, abrasion, and repeated flexing. EJ banded belts are suitable for large crushers, mining equipment, oversized compressors, bulk processing machinery, and extra-heavy drives. The maximum joined-rib quantity is 12.

Technical Data

Maximum Band Quantity by Length

Product Advantages

• Extra-heavy EJ construction keeps large rib groups operating as one unit
• 39 mm rib width and 44.5 mm pitch support oversized multi-groove drives
• Reinforced tensile members resist elongation under sustained high load
• Backing band helps suppress turnover, whip, and uneven rib tension
• Heavy rubber and fabric layers resist heat, oil, ozone, abrasion, and 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: EJ 220. The number of joined ribs must be confirmed separately.
