Spherical roller bearings
 
 
 
 
 

Spherical roller bearings are non separable de uble row radial bearings. Both rows of barrel shaped rollers rotate, in pa rallel, within the spherical outer ring. This allows an excellent alignment compensation, caused by machining and mounting errors, between the shaft and housing. Their boundary dimensions ara standardized by de din Standard 616 and din 635/parte2. Spherical roller bearings are typical bearings for heavy machinery and mining. They are suitable for applications with large ra- dial loads or where larger misalignments may occur. They are also able to support minor axial forces in both directions. Due to their kinematic behaviours, spherical ro ller bearings are only suitable for operating at low to medium speeds. NBI spherical roller bearings are produced in open design as standard. They are frequently used with tapered bores(ta- per 1: 12)namely suffix K except for series 240, 241, 248 and 249 where the taper bore (1: 30)is namely suffix K30, for ease of mounting. The facility of mounting these bearing types using adapter and extraction 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 ta pered seat of the shaft.
