High quality Thrust Roller Bearing 292/850

Description

1 The bearings are principally provided with two rows of symmetrical spherical rollers and a common sphere raceway in out ring, the two inner ring raceways are included at an angle to the bearing axia.

2 The bearings have good self-aligning ability and can operate when the shaft deflection under load or the shaft deflection under load or the shaft misaligning in mounting, and their permissible aligning angle is 1 to 2.5 degree.

3 The bearings have heavy load carrying capacity and anti-impact ability, in addition to radial loads, they also can carry axial loads in two directions

4 In general, this type of bearings permits a low limiting speed.
Spherical Roller Thrust BearingsSpherical roller thrust bearings are designed in such way that their rollers are spherical shape,and the raceway surface of housing washer is also spherical,so these bearings are self-alingned.According to the diameter series,the angles of misalignment are permissible within the range of 1~3.The larger the load,the smaller the angle.These bearings are separable formed bearings,and are featured by the extremely large axial load carrying capaibility and meanwhile they can also accommodate certain radial load.However,the radial load should not exceed *5% of the axial load anyaway.Since these bearings are self-aligning,they are not so sensitive to the mounting error and bending of the shaft.In order to prevent the rollers from sliding movement opposite to the raceway under the effect of the centrifugal force when the bearing is running,and form resulting in the circumstance of shaft and housing washer separated,therefore a certain axial load has to be carried by the operating bearings.Oil lubrication is commonly applied while these bearings are working.
