Browning 1001619 2TB48 2-groove Qd V-belt Sheave 5.15in

Product Description

The BROWNING 1001619 is a two-groove, QD bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical systems. Carrying the manufacturer designation 2TB48, this cast iron sheave features a 5.15-inch outside diameter and accepts bore sizes from 1/2 inch to 1-3/4 inch through a P1-style QD bushing. It is compatible with A, B, and 5V belt trade sizes, making it a versatile choice for blower and fan drive assemblies. Licensed HVAC and mechanical contractors install this type of sheave when setting up or adjusting belt-drive systems on air handlers, fans, and similar rotating equipment.

This sheave is suited for residential and light commercial HVAC systems as well as general industrial machinery where adjustable or fixed-speed belt drives are used. The QD bushing design allows for straightforward installation and removal without specialized bearing pullers, which is a practical advantage in equipment rooms or rooftop units where access is limited. No specific model compatibility data was provided by the manufacturer for this listing.
