China 6312 Deep Groove Ball Bearing - Versatile Solutions from Leading Suppliers and Factory

Features a low friction coefficient and elevated speed limit, making it ideal for high-speed or extremely high-speed industrial rotations.

Bearings equipped with dual dust caps or rubber seals are lubricated for life, delivering zero-maintenance operation under standard conditions.

Boasts a robust, straightforward configuration capable of accommodating both radial and bidirectional axial loads across extensive applications.

With a dynamic load rating of 85.2 kN and static load of 52 kN, the 6312 is ideal for moderate radial loads. For heavier axial loads, select models with expanded clearance or alternative axial designs.

Reference speed is 11,000 r/min with a limit speed of 7,000 r/min, tailored for high-speed machinery. For low-speed units, high load-carrying models may be considered.

Dimensions are 60mm × 130mm × 31mm (bore × OD × width). Confirm machine tolerances and mounting/dismounting spaces prior to integration.

For high-accuracy setups like precision instrumentation and high-speed spindles, higher manufacturing precision ratings (P5, P4, P2) are available.

Pre-lubricated for life; no additional grease replenishment is needed during operation. Maintain thermal operating limits within -30 °C to +120 °C to preserve seal integrity.

Require regular inspection and relubrication. Select appropriate industrial grease based on operating variables and replenish on schedule. Ensure clean surrounding environments to prevent particulate contamination.
