Thin section deep groove ball bearing 61938 190x260x33 mm
Thin section bearings of the 69 series have considerably smaller dimensions than deep groove ball bearings of the 60, 62, 63 and 64 series with their thin, square cross section at the same inside diameter. Relatively high shaft- and axis diameters can thereby be installed at an also extremely confined installation space. They are extremely light and are suitable for comparatively high speeds. Used extensively in machine tools, textile machinery and jet engine gearbox applications.
