Browning 1043132 2BK110H Qd V-belt Sheave 2 Groove 10.75 in

Product Description

The BROWNING 1043132, model 2BK110H, is a two-groove, QD bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It features a 10.75-inch outside diameter and accepts an H-style QD bushing, allowing bore sizes from 0.375 inches up to 1.5 inches. The cast iron construction provides the durability and mass needed for continuous-duty belt drive service. Compatible with both A and B cross-section V-belts, this sheave is a standard component for air handling units, blowers, fans, and other rotating equipment where adjustable bore sizing simplifies installation across a range of shaft diameters.

This sheave is suited for residential and commercial HVAC fan assemblies, industrial blower drives, pump drives, and general power transmission setups requiring a two-groove V-belt configuration. The H-style QD bushing system allows the sheave to be mounted and removed from the shaft without damage to the hub or shaft, making it a practical choice for systems that require periodic belt or drive changes. Licensed HVAC technicians and industrial mechanics are the typical installers.

Installation Notes

Installation and removal should be performed by a qualified mechanic or HVAC technician with the drive system fully de-energized and locked out per OSHA lockout/tagout procedures. Use the appropriate QD bushing hardware and follow the bushing manufacturer torque sequence to ensure even seating. Verify belt alignment and tension after installation before returning the system to service. Do not exceed the maximum bore diameter of 1.5 inches for the H-style bushing.
