Product Overview: The H 212 Adapter Sleeve
The H 212 Adapter Sleeve is a crucial component for mounting bearings with a tapered bore onto cylindrical shafts. As part of our reliable H 200 Series, this sleeve is designed specifically for shafts with a 55mm diameter, enabling the secure fitment of bearings with a 60mm bore. Adapter sleeves are one of the most commonly used components for locating bearings, as they allow for the use of standard, commercially available shafts while simplifying the mounting and dismounting process. The H 212 comes as a complete assembly, including a corresponding KM 12 lock nut and MB 12 lock washer, providing a full solution for your mechanical assembly needs.
These sleeves are essential in a wide range of industrial machinery, ensuring that bearings are firmly positioned against the shaft shoulder and operate with the correct radial clearance. Explore our complete collection of Adapter Sleeves to find the perfect mounting solution for your application.
Key Features of the H 212 Sleeve
