Product description

Excavator used bearings all types of excavator bearings features :

1) Excavator bearing specialized angular ball bearing are used for the appliion of excavator machinery.

2) Excavator angular contact bearing has big contact angle(40 degree), so can undertake big axial load .

3) Excavator bearing can carry heavier load capacity than the same size bearings because it has

4) High-accuracy, low-noise, long-life and this kink of bearing are widely used in excavator.

Ball bearings are used in a wide variety of appliions, they are simple in design, non-separable, suitable for high speeds and are robust in operation, and need 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.

Single row deep groove ball bearings are manufactured as open type (unsealed), sealed and shielded, the most popular sizes of deep groove ball bearings are also produced in sealed versions with shields or contact seals on one or both sides, the bearings with shields or seals on both sides are lubried for life and are maintenance free. A sealed bearings seals has contact on the bearings inner and outer, a shielded bearings shield has contact on the outer only, and Shielded bearings are primarily intended for appliions where the inner ring rotates.
