7009C Angular Contact Ball Bearing – Built for High Speed & Precision

With a 15° contact angle, the 7009C bearing delivers low heat generation and high rigidity at high rotational speeds. The optimized ball and cage configuration supports both radial and unidirectional axial loads, making it ideal for machine tool spindles, pumps, and high-speed motors.

• High Speed Capability: Reduced rolling resistance enables a 25% higher limiting speed compared to standard bearings, with significantly lower temperature rise.

• Rigidity & Accuracy: Available in P5/P4 precision classes; adjustable preload enhances overall spindle system stiffness.

• Low Noise, Long Life: Super-finished raceways combined with high-quality grease ensure smooth operation and extended maintenance intervals.

• Strong Interchangeability: Strictly follows ISO dimensional standards for seamless replacement of imported bearings.
