Browning 1TB70 Single Groove Pulley

The Browning 1TB70 single-groove pulley is a cast-iron V-belt sheave with a 7.35 in outer diameter designed for A or B belt-section drives. The unit features a 7.35 in outer diameter and a 1 in face width to match common Browning shafts and hubs. It uses a split-taper bore and requires a Browning bushing (P1 series) to fit shaft bore sizes from 1/2 in to 1-3/4 in. This 1-groove, close-grain casting provides tight tolerances for belt alignment and aligns with Browning's standard hub configurations for single-groove belts. For installation, the pulley is paired with a Browning split-taper bushing to secure it to the shaft, enabling reliable operation in compact drive assemblies. The 1TB70 is specified for single-groove V-belt drives and is built to Browning's engineering standards for durable, long-life performance in belt drive systems.
