T.B. Woods MS-58 Variable Pitch Sheave Pulley

TB Wood's MS-58 Variable Pitch Sheave Pulley is an adjustable-pitch belt-drive pulley that enables changing drive ratios without swapping pulleys. It features a 5/8 inch (0.625") bore and is rated for up to 8,900 RPM, making it suitable for precise speed matching in small to mid-size belt-driven systems. As part of the TB Wood's MS series, the MS‑58 is designed to integrate with TB Wood's standard belt drives and mounting interfaces, providing a practical solution for applications where variable speed or fine-tuning of motor speeds is required. Typical uses include small motors driving fans, pumps, and light-duty conveyors, where convenient, on-demand adjustment of output speed can improve process efficiency or system performance.
