Ningbo KENT bearing Co.,Ltd is located in Cixi Ningbo, Zhejiang China. We are ball bearings factory manufacturer and wholesaler specialized in producing bearings for more than 20 years.
Deep groove ball bearings are the most widely used rolling bearings, featuring simple structure, high versatility and reliable performance. They are mainly designed to bear radial loads, and can also withstand moderate axial loads in both directions.
With low friction coefficient, high limiting speed and excellent running stability, these bearings support high-speed rotation with low noise and vibration. The open, sealed and shielded types are available to adapt to dusty, humid and ordinary working environments.
Widely applied in motors, motorcycles, automobiles, general machinery, agricultural equipment and transmission parts, our deep groove ball bearings adopt high-quality steel materials, precise machining and strict quality inspection to ensure long service life and stable operation.
Professional replacement bearing for motorcycle and auto parts. Optimized internal structure realizes flexible rotation and strong shock resistance. Great heat dissipation and abrasion resistance make it suitable for engine, wheel hub, clutch and suspension system. Sealed structure effectively blocks dust, water and impurities to prevent early damage.
