3214 B-2RSRTNG NSK Double Row Angular Contact Ball Bearing 70mm x 125mm x 39.7mm
3214 B-2RSRTNG NSK Double Row Angular Contact Ball Bearing
This robust NSK double row angular contact ball bearing is engineered for high-speed precision applications requiring simultaneous radial and axial load capacity in a compact design. The 3214 B-2RSRTNG combines efficient load distribution across two rows with dual lip seal protection, making it ideal for demanding industrial equipment including gearboxes, spindles, pumps, electric motors, and heavy-duty rotating machinery.
Key Specifications:
- Bore Diameter: 70mm
- Outer Diameter: 125mm
- Width: 39.7mm
- Row Type: Double row configuration
- Contact Angle: 40 degrees for optimal combined load handling
- Arrangement: Bearing pair with low axial clearance in O- and X-arrangement
Design Features:
- Manufacturer: NSK - precision bearing technology and reliability
- Material: Standard bearing steel for durability and extended service life
- Cage: Polyamide cage for smooth, quiet operation and reduced friction
- Clearance: Normal radial clearance (P0/PN2 tolerance class - ABEC 1)
- Seal Type: Lip seals (2RS) on both sides for superior protection against contamination and moisture ingress
- Operating Temperature Range: -20°C to +120°C
- Outer Ring: Without flange or groove
Typical Applications:
This bearing is particularly suitable for automotive transmissions, industrial gearboxes, machine tool spindles, compressors, pump bearings, and other industrial applications where precise speed control, combined loading conditions in both directions, and sealed protection against harsh environments are essential. The dual lip seals make it especially effective in applications exposed to dust, moisture, or contamination.
