Allen-Bradley S1X3 15 16 Taper Locking Bushing

Allen-Bradley S1X3 3-15/16 in bore taper locking bushing is a split-taper locking device in the S1 family used to secure a drive component to a shaft by means of a precision taper and compatible taper-lock hubs. It features a 3-15/16 in bore, an outer diameter of 6-3/8 in, and a length of 4-3/8 in, making it suitable for large-bore power transmission assemblies. The bushing is manufactured in steel, with variants reported as C45 steel finished in black oxide, providing a robust, wear-resistant option for demanding applications. The taper angle is commonly specified as 8 degrees, a standard for many Taper-Lock style bushings, which contributes to secure engagement and easy removal when paired with the proper hub hardware. This size is intended for large-bore applications and is designed to integrate with standard taper-lock mounting practices to ensure a reliable, serviceable coupling between hub and shaft.
