4313 KOYO Double Row Deep Groove Ball Bearing

Deep groove ball bearings are versatile, self-retaining bearings. These bearings, which are of simple design, robust in operation and easy to maintain, are available in single row and double row designs and in open and sealed variants. The solid outer and inner rings have deep raceway grooves, with shoulders which are not generally interrupted by filling slots. Solid cages made from polyamide PA66 or brass, and sheet metal cages made from steel or brass, are used as standard cages. The bearings are open or sealed.

Suitable for predominantly radial loads:- The balls are in contact with the raceways at one point only. Under purely radial load, the contact points between the rolling elements and raceways lie at the centre of the raceway. As a result, the connection between the contact points passes through the radial plane, i.e. the optimum load direction is a pure radial load.

Capable of supporting axial loads in both directions:- Due to the deep raceway grooves in the bearing rings and the narrow osculation between the raceway grooves and balls, single row deep groove ball bearings can support axial loads in both directions. The axial load carrying capacity is dependent, for example, on the bearing size, the internal construction and the operating clearance. If the axial load is too high, however, this can increase the running noise and considerably reduce the operating life of the bearings.
