Browning 1TB52 Pulley Single Groove 5.2 Inch OD

Browning 1TB52 TB Gripbelt single-groove cast-iron pulley with a 5.55 in outside diameter and a 1 in face width is designed for TB Gripbelt drives that use A- or B-belt-section belts. This solid one-groove sheave uses a split-taper bore and accepts Browning bushings, with bore options from 1/2 in up to 1-3/4 in (P1-series bushings are used in these assemblies), enabling flexible shaft sizing. With its 5.55 in OD, the 1TB52 aligns with standard Browning TB-Gripbelt geometry and supports reliable belt alignment in compact drive zones. Typical applications include HVAC equipment, air handlers, conveyors, and other belt-driven systems where a single belt path provides power transmission. Cast-iron construction offers rigidity for consistent belt wear, while compatibility with Browning TB-series components helps ensure reliable interchangeability in retrofit or new installations. Designed for retrofit or new installations, it forms part of Browning’s TB Gripbelt family and can be paired with the accompanying TB bushings and hubs for a complete drive assembly.
