1. Consists of inner and outer rings with a closing plug and securing dowel, rolling elements, spacers, contact seals and lubrication nipples.  
2. Gear teeth on the outer ring, inner ring or without gear teeth.
3. Bearing rings with through holes or threaded holes for fixing screws.
4. Compact structure and light weight. 
5. Can support axial, radial and tilting moment loads at the same time. 

6. Professional Surface treatment such as blackening, galvanization(zinc-plating,zinc coating),antisepticize,corrosion prevention, rotproof, antiseptic, anticorrosive painting, etc. Ensure BRS Bearings function well under extreme working conditions.
