SINOCONVE SPCJ Type Banded Narrow V-Belts for Heavy Multi-Groove Systems with Superior Durability

SPCJ Type Banded Narrow V-Belt

SPCJ is a heavy-duty banded narrow V-belt with a 22 mm rib top width, 25.5 mm pitch distance, 21 mm height, and 40° belt angle. The product knowledge table lists an inside-length range of 87-4843 inches. The large SPC strands are joined by a heavy reinforced band to maintain stable spacing and coordinated torque transmission in wide multi-groove systems. High-strength tensile members provide dimensional stability under heavy load, while the banded construction helps suppress turnover, whip, and shock-related strand movement. Heavy rubber and fabric layers offer superior durability against heat, oil, ozone, abrasion, and flex fatigue. It is suitable for large compressors, crushers, heavy pumps, mining equipment, bulk processing machinery, and long-center drives.

Technical Data

Maximum Band Quantity by Length

Product Advantages

• Heavy SPCJ strands provide high-capacity transmission in large pulley systems
• Reinforced tie band maintains strand spacing over long center distances
• Superior durability supports demanding mining and bulk-processing equipment
• High-strength tensile members resist elongation under continuous heavy load
• Maximum joined-strand quantity increases from 20 to 30 by length range

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: SPC 87. The number of joined strands is confirmed separately according to the length and drive requirement.

Available Models

SPC 87 through SPC 4843 (continuous inside-length range)

Typical Applications

Large compressors, crushers, heavy pumps, mining equipment, bulk processing machinery, and long-center industrial drives.

Selection Notes

Please provide the production type, inside length, required number of strands, pulley groove dimensions, pulley width, drive power, speed, center distance, operating temperature, and load conditions. Final specifications and warranty terms are subject to the order contract.
