Angular Contact Ball Bearing 7007 CTRSULP3 NSK 35x62x14

Applications

The NSK 7007 CTRSULP3 is a high-precision single-row angular contact ball bearing, engineered for high-speed rotation and combined axial-radial loads. It is specifically designed for machine tool spindles (CNC), electrospindles, precision motors, metrology equipment, industrial automation, and planetary gear systems, where accuracy, rigidity, and vibration control are critical.

The 15° contact angle (C) provides excellent axial load capacity while allowing very high rotational speeds. The bearing can operate individually or in matched pairs (face-to-face / back-to-back), making it adaptable to different spindle and drive configurations.

Key Advantages

• Precision class P3 (LP3) for stable, low-vibration performance at high RPM.

• Polyamide cage (T / PA66) ensures reduced mass, lower heat generation, and quiet operation.

• Single-side sealing (RS) protects internal lubricant and extends service life.

• Universal pairing capability (U) allows flexible mounting options.

• High durability under continuous industrial duty cycles.
