SKF 61904 Open Thin Section Ball Bearing 20mm x 37mm x 9mm
Thin section 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 thin section ball bearings to accommodate axial loads in both directions.
An open ball bearing does not have any seals or shields, this enables the grease to flow freely through the bearing for lubrication purposes.
