SKF manufactures three different designs and series of ultra-precision single-row and double-row
cylindrical roller bearings. Some of the bearings are separable. They can accommodate axial
bi-directional displacement of the shaft relative to the housing, for example bearing rings with
roller and cage assemblies They can be separated from other rings. They simplify the mounting
and dismounting of bearings, especially under load conditions that require both bearing rings to
be in the case of interference fits.
