Overview
NSK 3318 Angular Contact Ball Bearing supports combined radial and one-direction axial load through a defined contact angle. It is a high-speed, high-precision choice for pumps, compressors, machine tools, and spindle-related positions where axial rigidity and rotational accuracy matter.
The inner and outer ring raceways are offset to create a contact angle. Single-row, double-row, or matched arrangements can be used to meet axial load direction, preload, and rigidity requirements.
Key features
- Supports combined radial and one-direction axial load
- High-speed and high-accuracy operation
- Preload and rigidity adjustable through matched mounting
- Suitable for precision rotating assemblies
Typical applications
- Machine tool spindles and support shafts
- Pumps and compressors
- High-speed motors
- Precision gearboxes and robot drives
Selection guidance
Select by contact angle, arrangement, preload, precision class, axial load direction, and operating speed.
