The JASON INDUSTRIAL 3L320 is a black rubber V-belt designed for industrial drive applications. Sized at 3/8 inch wide by 32 inches in outside circumference, this 3L-series belt transmits rotational power between sheaves in light- to medium-duty machinery. The rubber construction provides flexibility and grip across a range of operating conditions. Maintenance technicians, millwrights, and HVAC service professionals install this belt type on fan assemblies, compressors, pumps, and general-purpose power transmission equipment where a 3L cross-section profile is required.
The 3L320 fits standard 3L-series drive configurations found in residential and light commercial HVAC systems, agricultural equipment, and industrial machinery. It is suited for applications requiring a fractional-horsepower drive belt with consistent tension and dimensional stability over extended run cycles. The 32-inch length and 3/8-inch width match common OEM sheave pairings in blower and fan drive setups.
Designed as an OEM-style replacement for equipment requiring a 3L-series fractional V-belt in residential, commercial, and light industrial drive systems.
Installation is typically performed by licensed HVAC technicians, millwrights, or qualified maintenance personnel. De-energize all equipment and lock out or tag out power sources before removing or installing drive belts. Do not use tools to force the belt over sheave flanges — reposition the driven component to relieve tension before seating the belt. Check sheave alignment and belt tension after installation per equipment manufacturer guidelines.
