Chrome Steel Self-aligning 21304 CA Spherical Roller Bearings for Machine Tools
Spherical roller bearings with two rollers, mainly bear radial load, but also can withstand axial load in either direction. A high radial load capacity, especially suitable for work under heavy loads or vibration, but can not afford pure axial load. This kind of bearing outer ring raceway is spherical shape, aligning performance is good, can compensate concentricity error.
There are two rows of symmetrical spherical roller, a common spherical outer ring raceway, inner ring the two bearing axis tilted at an angle raceway has a good self-aligning properties, when the axial force bent or install a different heart is still bearing the normal use, transfer concentric with the bearing dimension series varies, generally allows aligning angle is 1 to 2.5 degrees, the type of bearing load capacity bearings can bear, in addition to radial loads two-way axial load, and has good impact resistance, generally self-aligning roller bearings allow lower operating speed.
