Adaptor Sleeves

Adaptor Sleeves are essential components for mounting tapered bore bearings onto cylindrical shafts with ease and precision. Widely used in industrial machinery, electric motors, gearboxes, and conveyor systems, these sleeves enable secure, adjustable bearing positioning while simplifying installation and removal.

Adaptor sleeves feature an external taper that matches the bearing bore, allowing the bearing to be mounted firmly by tightening a KM locknut (often with an MB lock washer). This setup ensures consistent axial clamping force, reduces shaft machining requirements, and accommodates standard shaft tolerances—making adaptor sleeves a cost-effective, versatile solution for shaft mounting.

Key features include:

Allows tapered bore bearings to be mounted on standard cylindrical shafts
Simplifies installation and removal without shaft modifications
Compatible with KM locknuts and MB lock washers for secure locking
Precision-machined tapers for consistent, accurate fit
Manufactured to ISO and DIN standards for interchangeability

Whether used in new assemblies or maintenance retrofits, Adaptor Sleeves provide a reliable, adjustable, and maintenance-friendly method for securing bearings in a wide variety of industrial applications.
