100 pcs630/8-2RS Low Noise Single Row Deep Groove Ball Bearing
⚙️Basic structure:
The 630/8-2RS adopts a single-row deep groove ball structure, consisting of an inner ring, an outer ring, a pressed steel cage, bearing steel rollers, and contact-type sealing rings on both sides. The inner ring is in a press-fit with the shaft, and the outer ring is in a clearance fit with the bearing housing. The rolling elements enable low-friction rotation.

Sealing protection: The 2RS contact-type sealing ring can effectively prevent dust, liquids and other contaminants from entering, and also prevent the leakage of internal lubricating grease, extending the service life by more than 30%;
Load capacity: It can withstand radial main load and bidirectional axial additional load. The basic rated dynamic load is 3.45 KN, and the static load is 1.37 KN;
Speed performance: When lubricated with grease, the maximum speed reaches 5000-8500 r/min. When lubricated with oil, it can be increased to 12000 r/min, suitable for medium-high speed scenarios;
Maintenance requirements: Factory pre-filled with lubricating grease, and there is no supplementary lubrication slot. Under normal operating conditions, almost no maintenance is required, reducing equipment operation and maintenance costs.
