Single Row Deep Groove Ball Bearings

Sealed bearings - ICOS® oil sealed bearing units

ICOS oil sealed bearing units have been developed by SKF. The new concept aims at applications where sealing requirements exceed the capabilities of standard sealed bearings. An ICOS unit (fig) consists of a 62 series deep groove ball bearing and an integral radial shaft seal. These units need less space than common two-component arrangements; they simplify mounting, and avoid expensive machining of the shaft because the inner ring shoulder is an excellent counterface.

The radial shaft seal is made of acrylonitrile-butadiene rubber (NBR) and has a spring loaded Waveseal lip. The permissible operating temperature range for the seal is –40 to +100 °C and up to +120 °C for brief periods.

The speed limits quoted in the product table are based on the permissible circumferential speed for the seal, which in this case is 14 m/s.
