Product Overview: The AHX 311 Withdrawal Sleeve
The AHX 311 is a high-precision withdrawal sleeve designed for dismounting bearings with a tapered bore from cylindrical shafts with a 50mm diameter. As a crucial component in our Bearing Accessories range, this sleeve is part of the AHX Series, which is a popular choice within our Withdrawal Sleeves collection. Withdrawal sleeves simplify the process of removing bearings from their seating, preventing damage to both the shaft and the bearing during maintenance or replacement. They are slit and feature an external taper, allowing them to be securely tightened onto the shaft using a corresponding lock nut.
Manufactured from high-quality steel, the AHX 311 ensures a reliable and secure fit. It is designed to be used with a variety of bearing types, such as self-aligning ball bearings and spherical roller bearings, making it a versatile solution for numerous industrial applications. When used with a KM 11 lock nut and MB 11 lock washer, it provides a complete and dependable mounting and dismounting system.
