Spherical Roller Bearings

Spherical roller bearings have two raceways in the inner and outer ring raceways between spherical, assembling the drum-shaped roller bearings.
Spherical roller bearings with two rollers, the main path of a load, but also can withstand axial load in either direction. A high radial load capacity, especially suitable for heavy work loads or vibration, but can not afford pure axial load. This kind of bearing outer ring raceway is spherical shape, so the self-aligning performance is good, can compensate concentricity error.
Spherical roller Stainless steel slewing bearing have two symmetrical spherical roller, there is a common spherical outer ring raceway, and the bearing inner ring with two axis tilt angle of the roller, with good self-aligning performance, when the axial force bending or install a different heart is still bearing normal use, transfer concentric with the bearing dimension series varies, generally allow aligning angle is 1 to 2.5 degrees, the type of bearing a larger load capacity, in addition to radial loads bearing can withstand two-way effect of axial load, has good impact resistance, generally spherical roller bearings allow lower operating speedused class of bearings. Main radial load, but also can withstand a certain amount of axial load deep groove ball bearings can be used for transmission, instrumentation, electrical, household appliances, internal combustion engines, transport vehicles, agricultural machinery, construction machinery, engineering machinery, etc.
Select a larger radial clearance axial bearing capacity increases, pure radial force, the contact angle is zero. Axial force, the contact angle is greater than zero. Commonly used stamping Ribbon Cage, machined solid cage, sometimes with nylon frame.
