SKF ICOS oil sealed bearing units, which are standard deep groove ball bearings with an integrated radial shaft seal, are also available

When capped bearings must operate under certain extreme conditions, such as very high speeds or high temperatures, grease may leak at the inner ring. For bearing arrangements where this would be detrimental, special design steps must be undertaken.

SKF deep groove ball bearings capped on both sides are lubricated for the life of the bearing and should not be washed or relubricated. They are filled with the appropriate amount of a high-quality grease under clean conditions. The bearings are considered virtually maintenance-free. If they are to be hot mounted, an induction heater should be used.

SKF does not recommend heating capped bearings above 80 °C (175 °F). However, if higher temperatures are necessary, make sure that the temperature does not exceed the permissible temperature of either the seal or grease, whichever is lowest.
