3211 C3 NSK Double Row Angular Contact Ball Bearing 55mm x 100mm x 33.3mm
The 3211 C3 NSK Double Row Angular Contact Ball Bearing is a precision bearing engineered to handle simultaneous radial and axial loads in both directions. This double row angular contact bearing from NSK combines robust construction with reliable performance, making it an excellent choice for demanding industrial applications requiring high-speed operation, precise load management, and enhanced load capacity compared to single row designs.
Key Features:
- Double row configuration for increased load capacity and bidirectional axial load handling
- Slightly increased radial clearance (C3) for optimal performance in applications with thermal expansion or preload requirements
- 30-40° contact angle for superior load distribution and combined load capacity
- Steel cage construction for enhanced durability and reliability
- Open bearing design (no seals) for minimal friction and high-speed capability
- Standard bearing steel construction with P0/PN2 (ABEC 1) tolerance class for precision performance
- Outer ring without flange or groove for flexible mounting options

Typical Applications:
This versatile double row angular contact bearing is ideal for high-speed, precision applications including spindle bearings, gearboxes, machine tool bearings, pumps, motors, and other heavy-duty equipment requiring simultaneous radial and axial load capacity in both directions. The double row configuration provides enhanced rigidity and load distribution compared to single row designs, making it particularly effective in applications where bidirectional loads are present. The 55mm bore size and slightly increased C3 clearance make it well-suited to medium machinery applications where thermal expansion or internal preload adjustments are anticipated. Its versatile design is particularly valuable in compressors, turbines, and transmission systems requiring robust, reliable bearing support.
