SINOCONVE 3V (9J) Type Banded Narrow V-Belts for Compact Drives with Stable Power Sharing

3V (9J) Type Banded Narrow V-Belt

3V (9J) is a banded narrow V-belt with a 9.7 mm rib top width, 10.3 mm pitch distance, 9.7 mm height, and 40° belt angle. The available inside-length range is 50-208 inches. Multiple narrow 3V ribs are joined by a reinforced tie band, allowing the belt set to run as one stable unit on compact multi-groove drives. The joined construction improves transverse rigidity, maintains rib spacing, and helps control wobbling, belt whip, and turnover. High-strength tensile cords support stable power sharing and low elongation, while the rubber and fabric structure provides good resistance to heat, oil, ozone, abrasion, and repeated flexing. It is suitable for compact fans, pumps, compressors, agricultural equipment, and workshop machinery.

Product Advantages

• Compact 3V banded profile transmits power efficiently in limited drive space
• Reinforced tie band maintains rib spacing and stable multi-groove tracking
• Equal power sharing helps reduce uneven loading between adjacent strands
• High transverse rigidity limits wobbling, turnover, and belt whip
• Low-elongation cords support dependable tension through repeated operating cycles

Structure

The belt assembly contains multiple narrow wedge strands, high-strength tensile cords, rubber compression layers, protective fabric, and a reinforced tie band. The tie band keeps the strands connected, controls lateral motion, and maintains the designed pitch distance between adjacent strands.

Model Naming Rule

Model = marking section + inside length in inches. Example: 3V 50. The number of joined strands is confirmed separately according to the length and drive requirement.
