Overview
NTN 6808OP Deep Groove Ball Bearing is a versatile rolling bearing for stable, low-friction rotation in a wide range of industrial equipment. It primarily supports radial load while accommodating moderate axial load in both directions, making it a standard choice for motors, pumps, gearboxes, and general machinery.
The bearing consists of inner and outer rings with deep raceway grooves, balls, and a cage. Open, shielded, or sealed designs can be selected according to contamination, lubrication, and maintenance requirements.
Key features
- Highly versatile standard bearing type
- Low friction and stable high-speed rotation
- Supports radial load and moderate bidirectional axial load
- Available in open, shielded, and sealed designs
Typical applications
- Electric motors and generators
- Pumps, fans, and blowers
- Gearboxes and reducers
- Conveyors and general industrial machinery
Selection guidance
Select by bore, outside diameter, width, sealing type, internal clearance, speed rating, and actual radial/axial load conditions.
