The W 13 withdrawal sleeve is engineered from high-quality carbon steel, designed specifically to secure spherical, barrel, or self-aligning bearings featuring a tapered bore (such as 22213 K or 23113 K series) onto standard cylindrical shafts. This critical accessory facilitates easy and precise bearing installation, eliminating the need for complex shaft modifications like machining seats or shoulders. Its robust, standardized geometry ensures a tight, uniform interference fit, minimizing fretting corrosion and providing superior load distribution under heavy industrial stress and fluctuating operational temperatures.
Choosing the W 13 guarantees exceptional reliability and optimized operational safety. Unlike standard mounting methods, the use of this standardized sleeve allows maintenance teams to accurately adjust radial internal clearance during installation, which is vital for maximizing bearing service life and preventing premature failure. Optimized for quick assembly and disassembly when paired with the requisite locking nut (e.g., KM 13), the W 13 withdrawal sleeve dramatically reduces maintenance downtime and lowers the total cost of ownership in demanding applications like heavy conveyors, mining machinery, and pulp and paper processing.
