Browning 4B46SD 4 Groove Cast Iron Bushed Bore Multiple Sheave

Browning 4B46SD is a four-groove cast-iron belt sheave with a bushed (SD) bore, designed for Browning Gripbelt A- and B-section V-belts. This Type A Solid pulley features a 4.95" outside diameter, a 3-1/4" face width, and an overall length of 4.95", with an SD bore that accepts shaft sizes from 1/2" to 2" using standard bushings. It provides two pitch diameters for belt sizing: 4.4" on the A-side and 4.9" on the B-side, enabling use with both A- and B-belts in a single four-groove configuration. The combination-groove design allows running A and B belts in Browning B sheaves to accommodate multiple drive layouts, while the pulley is machined from close-grain cast iron to tight tolerances for reliable performance. Suitable for light- to medium-duty belt-drive applications, this Browning V-belt pulley is built to offer durable, adaptable service with a 4-groove, cast-iron construction and a versatile SD-bore interface.
