W 22 Withdrawal Sleeve | Precision Mounting Component for 110mm Shafts | High Reliability Industrial Standard
The W 22 Withdrawal Sleeve is an essential, high-precision accessory designed for mounting spherical roller bearings or other components with a tapered bore onto a cylindrical shaft. Engineered to international standards (often interchangeable with H 3122 designation), this sleeve provides the critical mechanical interface required for secure and accurate axial location. By utilizing the sleeve's standardized taper (typically 1:12), controlled force application ensures the bearing is pressed firmly into position, achieving the correct operational clearance and maximizing load distribution. Constructed from high-strength, durable steel, the W 22 sleeve guarantees longevity and structural integrity even under harsh industrial operating conditions.
As a core component in minimizing downtime and ensuring bearing longevity, utilizing a precisely manufactured withdrawal sleeve like the W 22 is non-negotiable. Its design facilitates significantly easier dismounting compared to direct interference fits, allowing maintenance teams to swiftly replace or inspect bearings, thereby reducing Total Cost of Ownership (TCO). This sleeve is precision-machined to strict dimensional tolerances, ensuring a reliable fit and optimal transmission of mounting force. Choosing the W 22 ensures compatibility with high-quality bearings (such as SKF 222xx series mounted on a standard shaft), guaranteeing a robust assembly for critical applications across heavy industry, mining, and power generation.
