Overview
The SKF QJ 310 LA/P63 is a precision four-point contact ball bearing manufactured by SKF, a global leader in rolling bearing technology. This bearing is engineered to handle high axial loads in both directions while maintaining compact dimensions and operational efficiency. The LA/P63 designation indicates the precision class (P63) and locating feature configuration, making this bearing suitable for demanding industrial applications where load capacity and accuracy are critical.
Key Features
- Four-point contact design accommodates high bidirectional axial loads with minimal radial load support
- 35° contact angle optimized for axial load distribution and alignment stability
- Two-piece inner ring and one-piece outer ring configuration allows separate mounting of outer ring assembly
- Requires significantly less axial space than double-row angular contact bearings
- P63 precision class ensures consistent bore runout and raceway geometry
- Brass cage material for strength and reliable ball positioning
