Browning 3TB52 3 Groove Fixed Pitched Sheave Pulley

Browning 3TB52 is a fixed-pitch, three-groove V-belt pulley (sheave) from Browning’s TB series, cast in iron with a 5.55" outside diameter and a 2-1/2" face width. This 3-groove unit is designed for Gripbelt cross‑section belts (A, AX, B, BX) and is built as a fixed-pitch sheave for reliable, synchronized belt spacing across all grooves. It uses a bushed bore and accepts standard bushings to fit shaft diameters from 1/2" up to 1-3/4" with P1 split-taper bushings; QD-bushed configurations are also available on compatible assemblies. The 3TB52 designation identifies the triple-groove, fixed-pitch configuration intended to pair with Browning’s bore options for robust multi-groove belt drives.
