Designed for heavy radial loads, however can tolerate light or intermittent thrust loads. Speed capabilities comparable to ball bearings.
For high speed applications, machined brass cages are used.
Super precision double-row bearings are also available with close tolerances; ideal for use in machine tool spindles, etc. Sizes range from 0.7874″ (20 mm) inside diameter to 22.8346″ (580 mm) outside diameter.
