Adapter Sleeves (Locking Sleeves) are mounting accessories designed to install bearings with a tapered bore onto a plain (cylindrical) shaft quickly and securely. By tightening the lock nut, the sleeve drives the bearing up the taper to achieve the required interference fit, ensuring reliable positioning and stable operation. This structure simplifies installation and removal, reduces machining requirements on the shaft (no need for shoulders or special seating), and helps accommodate a wide range of shaft tolerances.

Adapter sleeves are widely used with spherical roller bearings, self-aligning ball bearings, and other tapered-bore bearings, and are suitable for applications exposed to vibration, heavy loads, and frequent maintenance. With robust steel construction and precise thread geometry, they provide dependable clamping performance in gearboxes, conveyors, fans, agricultural machinery, mining equipment, and general industrial machinery, where efficient bearing mounting and serviceability are critical.
