5308 SC3 NTN Double Row Angular Contact Ball Bearing 40mm x 90mm x 36.5mm
5308 SC3 NTN Double Row Angular Contact Ball Bearing
This premium double row angular contact ball bearing from NTN is engineered to handle combined radial and axial loads in both directions, delivering reliable performance in demanding industrial applications. The dual-row configuration provides superior load capacity compared to single-row designs, making it an excellent choice for precision machinery requiring robust bi-directional load handling and moderate speed operation.
Key Specifications:
- Bore Diameter: 40mm
- Outside Diameter: 90mm
- Width: 36.5mm
- Contact Angle: 25°
- Row Type: Double Row
- Brand: NTN
- Reference: 5308SC3
Features & Benefits:
- Double row configuration for enhanced load capacity in both radial and axial directions
- 25° contact angle optimised for balanced radial and axial load distribution
- Sheet steel cage design ensuring robust performance with reduced friction
- Open bearing design (unsealed) allowing unrestricted operation and direct lubrication access
- Slightly increased radial clearance for versatile mounting applications and thermal expansion accommodation
- Standard bearing steel construction for exceptional durability and reliability
- Tolerance class P0/PN2 / ABEC 1 providing consistent precision and performance
