Jason Industrial B87 Rubber V-belt 21/32 X 90 Inch

Product Description

The JASON INDUSTRIAL B87 is a black rubber V-belt designed for industrial power transmission applications. Sized at 21/32 inch wide by 90 inches in length, this belt transmits rotational power between sheaves in motor-driven equipment. V-belts in this class are standard components in blowers, compressors, pumps, and other belt-driven machinery found in HVAC, industrial, and mechanical systems. Installation is performed by maintenance technicians and mechanical contractors as part of routine equipment service or belt replacement jobs.

The B87 fits B-section V-belt drive systems commonly found in commercial and industrial equipment. The 90-inch outside circumference suits drives requiring a longer belt span, including large air handlers, industrial fans, and pump assemblies. This belt is sold in a package quantity of 20 units, making it suitable for stocking in maintenance shops or fleet service operations that handle high volumes of belt replacements.

Installation Notes

V-belt replacement is typically performed by mechanical or HVAC service technicians. Always de-energize and lock out the equipment before removing or installing belts. Adjust drive tension per the equipment manufacturer specifications after installation and re-check after initial run-in. Inspect sheaves for wear or misalignment before fitting a new belt to avoid premature failure.
