Product Overview: The H 212 Adapter Sleeve
The H 212 adapter sleeve is a crucial component designed for securely mounting tapered bore bearings onto cylindrical shafts. This versatile sleeve provides a simple and effective method for bearing installation, especially where precise machining of a shaft seat for a direct fit tapered bore bearing might be impractical or costly. With a bore diameter of 55 mm (designed for a 55mm shaft), an outer diameter of 65 mm (to fit the bearing's tapered bore), and a total length of 45 mm, the H 212 ensures a stable and concentric fit.
As part of our comprehensive H 200 Series and overall Adapter Sleeves range, the H 212 adapter sleeve facilitates quick and reliable bearing assembly and disassembly, making it an indispensable part for various industrial applications. Its robust construction ensures excellent grip and reduced risk of fretting corrosion, contributing to the extended service life of the bearing and the machinery.
Key Features of the H 212 Adapter Sleeve
- Secure Tapered Mounting: Enables the secure mounting of tapered bore bearings (e.g., 22212, 23212 Spherical Roller Bearings) onto plain cylindrical shafts.
- Easy Installation and Removal: Designed for straightforward mounting and dismounting using a lock nut and lock washer, simplifying maintenance procedures.
- Cost-Effective Solution: Eliminates the need for precise machining of shaft shoulders or steps, reducing manufacturing costs.
- Shaft Size Accommodation: Can compensate for minor inaccuracies in shaft diameter, providing a precise fit without extensive modifications.
- Enhanced Concentricity: Ensures that the bearing is mounted concentrically on the shaft, optimizing performance and extending operational life.
- Robust Construction: Manufactured from high-quality materials to withstand demanding industrial environments and provide lasting reliability.
Common Applications of H 212 Adapter Sleeves
- Conveyor Systems: Used in various types of conveyors to mount bearings on long, unmachined shafts.
- Paper Making Machinery: Provides reliable bearing support in high-speed, continuous operations where stability is critical.
- Textile Machinery: Ensures smooth rotation and efficient operation in spinning and weaving equipment.
