Detailed Product Description
Ningbo Kent Bearing Co.,Ltd is bearing factory specialized in designing and manufacturing a variety of precision, top quality ball bearings for electric motors, automobiles, household appliances, power tools, pumps, motorcycles, heavy vehicles, machines etc.
Versatile Compatibility
Available in open, sealed (2RS, ZZ) and shielded configurations, our thin wall bearings support both radial and axial loads (single row) or combined loads (double row). They are compatible with a wide range of operating temperatures (-40°C to 120°C, extendable to 200°C with special grease) and can be customized with different lubricants to meet specific application needs.

High Precision & Low Noise

Manufactured with strict tolerance control (ISO Class P0-P6) and advanced grinding technology, our thin wall ball bearings deliver exceptional rotational accuracy and smooth operation. The precision raceways and high-quality balls minimize friction and vibration, resulting in low noise levels, which is crucial for precision instruments and quiet-running equipment.

Long Service Life 
The combination of high-quality materials, precision manufacturing, and effective sealing (to prevent dust, moisture, and contaminants) ensures a long service life and reduced maintenance frequency, lowering overall operational costs for your equipment.
