NSK Angular Contact Ball Bearings (7011, 7012, 7013, 7014, 7016) are precision-engineered for high-speed, high-load applications. Available in C (15° contact angle) and AC (25° contact angle) configurations, these bearings optimize axial/radial load distribution.
| Model | Bore Diameter (mm) | Outer Diameter (mm) | Width (mm) | Dynamic Load (kN) | Static Load (kN) | Speed Limit (rpm) |
|---|---|---|---|---|---|---|
| 7011C | 55 | 90 | 18 | 32.5 | 24.0 | 9,500 |
| 7012AC | 60 | 95 | 18 | 34.2 | 26.8 | 9,000 |
These bearings are critical in:
A manufacturer replaced tapered roller bearings with NSK 7012C bearings in CNC spindles, achieving 22% higher RPM and 15% longer service life.
7016AC bearings enabled 40% weight reduction in EV motor shafts while maintaining 12,000 rpm operational stability.
Challenge: Frequent bearing failures in turbine test rigs at 850°F.
Solution: Custom-coated 7014AC bearings with ceramic hybrid balls.
Result: 300% lifespan increase; $220K annual savings.
Challenge: Vibration issues in robotic arms under multi-axis loads.
Solution: Preloaded 7013C bearings in paired configuration.
Result: 0.002mm positional accuracy achieved.
