Browning 1001197 2TB34 2-groove Qd Bushed V-belt Sheave

Product Description

The BROWNING 1001197, model 2TB34, is a two-groove, QD bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical equipment drives. It features a 3.75-inch outside diameter and accepts a P1-style QD bushing to accommodate bore diameters ranging from 0.5 inches to 1.75 inches. Cast from iron for durability in continuous-duty environments, this sheave is compatible with A, B, and 5V belt trade sizes, with a belt pitch A diameter of 3.0 inches and a belt pitch B diameter of 3.4 inches. HVAC technicians and mechanical contractors install this sheave on blower assemblies, fan drives, and auxiliary equipment requiring a compact, dual-groove drive arrangement.

This sheave is suited for residential and light commercial HVAC air handlers, rooftop units, and industrial blower assemblies where a two-groove belt drive is specified. The QD bushing design simplifies installation and removal without requiring specialized machining, making it a practical choice for field replacements and new drive system builds. It is well-suited wherever A, B, or 5V cross-section belts are used in belt-driven fan or blower configurations.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out all power to the drive system before removing or installing the sheave. The P1 QD bushing must be ordered separately and properly torqued per the bushing manufacturer specifications. Verify belt alignment and tension with appropriate gauges after installation to prevent premature belt and bearing wear.
