SINOCONVE SPAJ Type Banded Narrow V-Belts for General Machinery with Stable Power Transmission

SPAJ Type Banded Narrow V-Belt

SPAJ is a banded metric narrow V-belt featuring a 13.6 mm rib top width, 15.6 mm pitch distance, 12.3 mm height, and 40° belt angle. Its inside-length range is 51-209 inches. The joined SPA strands provide a balanced combination of compact geometry, stable power transmission, and transverse rigidity. A reinforced top band maintains strand spacing and load sharing across the multi-groove pulley, helping reduce vibration, turnover, and irregular tension. High-strength cords limit elongation, while the durable rubber and fabric construction offers good resistance to heat, oil, ozone, abrasion, and flex fatigue. SPAJ belts are suitable for fans, pumps, compressors, generators, agricultural machinery, and general industrial equipment.

Technical Data

Maximum Band Quantity by Length

Product Advantages

• Balanced SPAJ geometry supports efficient power transmission in general machinery
• Reinforced band maintains uniform load sharing across metric pulley grooves
• Stable strand spacing helps reduce vibration and irregular sidewall wear
• High-strength cords control elongation during continuous operation
• Good resistance to heat, oil, abrasion, ozone, and flex fatigue

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: SPA 51. The number of joined strands is confirmed separately according to the length and drive requirement.
