5205 ZZC3 Nachi Double Row Angular Contact Ball Bearing 25mm x 52mm x 20.6mm
5205 ZZC3 Nachi Double Row Angular Contact Ball Bearing
The 5205 ZZC3 is a premium double row angular contact ball bearing from Nachi, engineered to handle combined radial and axial loads in both directions. This versatile bearing combines robust construction with protective sealing, making it an excellent choice for industrial applications requiring reliability, precision performance, and extended maintenance intervals. With a slightly increased radial clearance configuration, this bearing accommodates thermal expansion and operational variations commonly encountered in demanding environments.
Key Features:
- Double row construction for superior bidirectional axial load capacity
- 30° contact angle optimized for balanced radial and axial load distribution
- Slightly increased radial clearance (C3) accommodates thermal growth and minor misalignment
- Sheet steel cage construction for durability and cost-effective operation
- Metal covers on both sides providing protection from contamination and dust ingress
- Standard bearing steel construction for proven durability and longevity
- Tolerance class P0/PN2 (ABEC 1) for dependable industrial performance
- Standard arrangement configuration for universal compatibility
