deep groove ball bearing Design feature: Single row deep groove ball bearings are particularly versatile. They are simple in design, non-separable, suitable for high and even very high speeds and are robust in operation, requiring little maintenance. Deep raceway grooves and the close conformity between the raceway grooves and the balls enable deep groove ball bearings to accommodate axial loads in both directions, in addition to radial loads, even at high speeds. We can produce the diameter from 3mm~1 500mm LHB single row deep groove ball bearings. 10mm~100mm LHB double row deep groove ball bearings,and LHB sealed single row deep groove ball bearings,single row deep groove ball bearings with filling slots etc. Following is the internal structure of LHB different product descriptions.
