SKF Deep Groove Ball Bearing 6311NR Open C/W Snap Ring

Single row deep groove ball bearings are one of the most common types of ball bearing in use, this is down to their versatility. They are simple in design, suitable for high speeds, non-separable, are very robust in operation and require very little maintenance. Deep raceway grooves and the close conformity between the grooves and the balls enable deep groove ball bearings to accommodate axial loads in both directions, even at high speeds. The snap ring groove simplifies arrangement design as the bearings can be axially located in the housing by the snap ring.
