7212 BECBJ Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 40° contact angle provides excellent resistance to axial loads from one direction and significant radial loads. The calculated distance from side face to load point (47 mm) contributes to stable moment load support.
- Precision Performance: Manufactured to P6 tolerance class, this bearing ensures minimal runout and vibration, critical for high-speed and high-precision applications.
- High-Speed Capability: The lightweight, robust stainless steel cage (suffix J) maintains ball guidance and stability, enabling operation at the specified limiting speed of 7,500 rpm.
- Material Integrity: Constructed from chrome steel for rings and balls, the bearing offers high fatigue life and wear resistance, suitable for a wide temperature range of -30°C to 110°C.
