Spherical Roller Bearings are non - separable double - row radial bearings.
Both rows of barrel shaped rollers rotate, in parallel, within the spherical outer ring. This allows an excellent alignment compensation, caused by machining and mounting errors, between the shaft and housing.Spherical roller bearings are typical bearings for heavy machinery and mining.They are suitable for applications with large radial loads to or where larger misalignments may occur. They are also able to support minor axial forces in both directions.Due to their poor kinematic behaviours, spherical roller bearings are only suitable for operating at low to medium speeds. Mouken Spherical roller bearing are produced in open design as standard.
They are frequently used with tapered bores (i.e. taper 1:12) namely suffix K or for series 240 and 241 the taper bore is (1:30) namely suffix K30, for ease of mounting.
The facility of mounting these bearing types using adapter and withdrawal sleeves enables mounting directly onto drawn or fine turned seats of shaft for applications where high running accuracy is not necessary.
For some applications it remains necessary to mount tapered bore bearings directly onto a tapered seat of the shaft.
