3313 B-2RSRTNG NSK Double Row Angular Contact Ball Bearing 65mm x 140mm x 58.7mm
3313 B-2RSRTNG NSK Double Row Angular Contact Ball Bearing
The 3313 B-2RSRTNG is a premium double row angular contact ball bearing from NSK, engineered for high-speed precision applications requiring simultaneous radial and axial load capacity. This robust bearing is ideal for demanding industrial equipment including gearboxes, spindles, compressors, and heavy-duty machinery requiring reliable performance in moderate temperature environments.
Key Specifications:
- Dimensions: 65mm bore × 140mm outside diameter × 58.7mm width
- Design: Double row angular contact configuration with 40° contact angle
- Cage: Polyamide cage for optimized performance and durability
- Clearance: Normal radial clearance with low axial clearance in O- and X-arrangement bearing pair configurations
- Sealing: Lip seals on both sides (2RS) for enhanced protection against contamination
- Material: Standard bearing steel construction
- Outer Ring: Without flange or groove
- Temperature Range: -20°C to +120°C
- Tolerance Class: P0/PN2 (ABEC 1)
- Arrangement: Bearing pair with low axial clearance - suitable for O- and X-arrangement configurations
Applications:
This bearing is particularly well-suited for applications requiring high-speed rotation and precision performance, including automotive transmissions and differentials, industrial gearboxes, machine tool spindles, and specialized industrial machinery. The double row configuration provides enhanced load capacity, while the low axial clearance bearing pair arrangement in both O- and X-configurations provides versatile mounting options for demanding applications where precision alignment and load distribution are critical. The integrated lip seals offer superior protection in moderately contaminated environments.
