544B Quick Detachable Sheave

The 544B is a four-groove V-belt pulley designed for power transmission systems. It accepts a quick-detachable SD bushing with a bore range of 1/2 in to 1-15/16 in. The sheave supports multiple belt cross-sections including 4L, 5L, A, AX, B, and BX sizes. It provides a secure mechanical connection for industrial drive applications.

Suits multi-belt drives needing quick bore changes

This sheave fits maintenance teams that value rapid bushing swaps without pulling the shaft. It covers standard A and B belt families in a single four-groove casting. Operations requiring C-section belts or non-SD bushing types must select a different model. Single-groove or fixed-bore requirements are also outside its scope.

Handles A and B belts with 5.4 in pitch diameter

The 5.4 in pitch diameter on B and BX belts delivers consistent speed ratios and power capacity for typical industrial loads. Four grooves share the load evenly across the drive. The design reaches its limit when an application calls for C or CX belts, larger pitch diameters, or a bushing style other than SD.
