Hongjing HMK Self-aligning ball bearing is designed with spherical outer ring raceway and double inner ring ball grooves. Its core advantage is automatic self-aligning function to offset shaft bending, mounting misalignment and housing deviation within 2~3 degrees. Two bore options: cylindrical straight bore and 1:12 tapered bore for adapter sleeve mounting, open type and double-side 2RS rubber sealed structure to stop dust & grease leakage. HMK produces complete 1200/1300/2200/2300 series self aligning ball bearings for global wholesale.

Core Features

1. Auto self-aligning performance: Tolerate installation error and shaft bending, reduce early bearing damage from misalignment

2. Dual load capacity: Mainly bear radial load, support moderate bidirectional axial load, stable under complex working condition

3. Low friction & low noise: Smooth rolling, low heat generation, fit medium-high speed running equipment

4. High quality raw material: Whole bearing made of GCr15 chrome bearing steel, through precision heat treatment & ultra-precision grinding, long service life

5. Multiple structure options: Open / double-side rubber seal 2RS; straight bore / tapered bore; pressed steel cage / solid brass cage

6. Full size range: Complete metric sizes from miniature to large dimension, interchangeable with SKF/NSK standard sizes
