Jason Industrial 3L280 Rubber V-belt 3/8 X 28 Inch

Product Description

The JASON INDUSTRIAL 3L280 is a fractional-horsepower rubber V-belt designed for light-duty industrial and commercial drive applications. Built to the 3L cross-section standard, it measures 3/8 inch wide with a 28-inch outside circumference. This belt transmits rotational power between sheaves in belt-driven equipment, handling the mechanical loads common in small motors, fans, blowers, and auxiliary machinery. Licensed HVAC technicians, industrial maintenance mechanics, and equipment service professionals install this type of belt as a direct replacement during routine drive maintenance.

The 3L280 suits fractional-horsepower drive systems found in residential and light commercial equipment. Typical applications include belt-driven blower assemblies, small compressors, agricultural equipment, shop tools, and HVAC air handlers where a 3L-section belt is specified. The 28-inch outside circumference makes it appropriate for moderate center-distance drive configurations. This belt is sold in cases of 50 units, making it practical for distributors, service fleets, and facilities with high belt-replacement volume.

Key Features

• 3L cross-section: 3/8 inch wide, suited for fractional-horsepower drives
• 28-inch outside circumference for moderate center-distance sheave arrangements
• Rubber construction provides flexibility and resistance to wear in drive service
• Black finish standard for industrial V-belt applications
• Sold in a 50-belt case quantity for high-volume service operations

Compatibility

Designed as an OEM-style replacement for 3L-section V-belt drive systems requiring a 28-inch outside circumference belt in fractional-horsepower applications.

Installation Notes

A licensed mechanic or qualified service technician should de-energize and lock out the equipment before replacing a drive belt. Loosen the drive motor mounting to relieve tension before removing the old belt, then seat the new belt in the sheave grooves without using tools to force it over the flanges. Re-tension the belt according to the equipment manufacturer's deflection specification and verify sheave alignment before restoring power.
