Feature

 

Single row deep groove ball bearings are used inVarious of applications, they are simple in design, non-separable, suitable for high speed 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 load in both directions, in addition to radial load.

Single row deep groove ball bearings are manufactured as open type (unsealed), sealed and shielded, the most popular size 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 lubricated for life and arefreeMaintenance. 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 applications where the inner ring rotates. If the outer ring rotates, there is a risk that the grease will leak from the bearing at high speed.

MR52ZZ Miniature Bearings are ideal for the application such as power tools, scooters, skateboard, remote control plane,boat and cars, textile machinery etc.
