Browning 3TC90 Pulley 3 Groove

Browning 3TC90 is a three-groove V-belt pulley engineered for C-belt-section drives, delivering a 9.4-inch outer diameter and the ability to accommodate three distinct belt configurations on one shaft, which can simplify retrofits and tune-ups for multi-speed or multi-load systems. Constructed from close-grain cast iron, this pulley is designed to hold tight tolerances for consistent belt sit and alignment, providing reliable torque transfer and long service life in demanding industrial environments. The mounting arrangement uses a split-taper Browning Q1-series bushing, meaning a bore size is not pre-bored and a compatible bushing must be selected to suit the shaft, ensuring a secure and precise fit. Commonly used in belt-driven HVAC and industrial equipment to transmit rotational power between shafts, the 3TC90's C-belt section designation and three-groove geometry offer a compact, robust solution for conveyors, fans, blowers, and other utility-driven machinery.
