3313 BTNGC3 NSK Double Row Angular Contact Ball Bearing 65mm x 140mm x 58.7mm
The 3313 BTNGC3 NSK Double Row Angular Contact Ball Bearing is a high-performance precision bearing engineered to handle simultaneous radial and axial loads in both directions. As a double row angular contact bearing, it delivers superior load-carrying capacity and rigidity compared to single row designs, making it an ideal choice for demanding industrial applications requiring enhanced stability and durability.
NSK manufactures premium quality bearings renowned for their reliability and precision across a wide range of industrial sectors. This larger capacity double row bearing combines advanced engineering with robust construction to meet the exacting demands of heavy-duty machinery and equipment.
Key Features:
- Double row design for increased load capacity and exceptional rigidity
- 40° contact angle for optimal radial and axial load distribution
- Open bearing design (no seals) allowing for external lubrication and easy maintenance
- Polyamide cage design for stable ball retention and reduced friction
- Standard bearing steel construction for durability and long service life
- Slightly increased radial clearance for improved operational flexibility
- Tolerance class P0/PN2 (ABEC 1) for consistent precision performance
- Bearing pair configuration with low axial clearance in O- and X-arrangements

Applications:
This bearing is ideal for high-speed, precision applications including automotive transmissions, gearboxes, electric motors, spindles, pump shafts, and compressors. The double row configuration and larger bore size make it particularly suitable for heavy-duty equipment requiring enhanced load capacity and operational stability under combined radial and axial loading conditions. The open bearing design allows for flexible external lubrication strategies, making it well-suited for industrial applications where custom lubrication systems or environmental considerations require unsealed bearing configurations.
