TB Wood's SGB4G50-500RPM-2INBORE-STD-SUREGRIP Pulley

TB Wood's SGB4G50-500RPM-2INBORE-STD-SUREGRIP is a four-groove V-belt pulley with a 50-inch outside diameter and a 2-inch bore, designed to accept TB Wood's standard Sure-Grip bushings (non-QT). The pulley is statically balanced for true-running and long service life, and Sure-Grip pulleys are rated for rim speeds up to 6,500 feet per minute, making this large-diameter unit suitable for lower-to-mid-speed drives that demand stable belt tension. With four grooves, it accommodates four belts in a single drive, boosting power capacity and simplifying the drive layout in compact footprints. The STD-SUREGRIP designation indicates the standard bushing configuration, enabling quick installation and removal while maintaining secure shaft engagement. This pulley is well suited as a main or companion pulley in industrial equipment such as conveyors and processing lines, where a large-diameter, low-speed drive helps reduce belt tension fluctuations and improve belt life.
