The deep groove ball bearing 63800 series is a widen version of 6800 series, and they are same in bore size and outer diameter, but the height is widen. Therefore, the 63800 series bearings have similar load capacities of the 6800 types.


63800 Types single row deep groove ball bearings have same structure as standard bearings, consisting of an outer ring, an inner ring, a set of steel balls and a set of cages. They are simple in construction as well as easy to operate and maintain. The bearing ring grooves are circular arcs made slightly larger than the radius of the ball. The balls make point contact with the raceways (elliptical contact when loaded). The inner ring shoulders are of equal height (as the outer ring shoulders).


They can run at high speeds and can support both radial and axial loads, furthermore they are robust, versatile and quiet running. This bearing type can be produced to provide both high-running accuracy and high-speed operation.



The widen series deep groove ball bearings are widely used in instruments or robotics bearings, aerospace bearings, rilling, milling or grinding spindles, medical equipment bearings, and any industrial application where space is at a premium or weight reduction is required.
