22308MAK spherical roller bearing 40x90x33mm
1.Description of spherical roller bearing:
1)Spherical roller bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The inner rings have cylindrical or tapered bores.The symmetrical barrel rollers orient themselves freely on the concave outer ring raceway.
2)This type bearings are self-aligning and consequnently insensitive to misalignmient of the shaft relative to the housing and to shaft deflection or bending.
3) The bearings are leading in design with many series such as 213..-, 222,
230, 239, 240, , 241,223, , 231, 232, 233, 241
4)The differences of the bearings include the arrangement of the floating guide ring and the design of the inner ring and/or cages.
