Browning 1001312 Qd Bushed V-belt Sheave 2 Groove

Product Description

The BROWNING 1001312 is a two-groove, QD bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It features a 4.15-inch outside diameter and accepts bore sizes from 0.5 inches up to 1.75 inches through a P1 bushing style, giving technicians flexibility when matching it to a wide range of shaft sizes. The sheave carries a belt pitch A diameter of 3.4 inches and a belt pitch B diameter of 3.8 inches, making it compatible with both A-section and B-section V-belts. At 3.1 pounds, it is a compact, durable component suited for fan drives, blower assemblies, and motor-to-load drive configurations.

This sheave is commonly used in rooftop units, air handlers, belt-drive blower assemblies, and light industrial machinery where a two-groove V-belt drive is required. The QD bushing design allows for quick installation and removal without special tooling, making it a practical choice for service technicians performing scheduled maintenance or drive replacements. It is sold individually and is appropriate for both new installations and direct drive replacements.
