Spherical Roller Bearings

Spherical Roller Bearings Spherical Roller Bearings

LYC’s spherical roller bearing consists of an outer ring with spherical raceway and an inner ring with double-raceway, one or two cages, and one group of spherical rollers. Due to the center of spherical raceway of outer ring which is coinciding with the center of bearing, this makes it have a self-aligning property. This kind of bearing can adjust angular error or deflection caused by the angle of the axle and bearing housing or axle bend. LYC’s spherical roller bearing has a high load carrying capacity for radial load and axle load in two directions. It is especially suitable for carrying heavy loads and impact loads, but this type of bearing permits a lower limiting speed. The permissible aligning angle of the spherical roller bearing working in normal conditions is 1° ¡«2.5°. If bearings of this type have seals, then this function would be reduced.

Minimum Load-Spherical Roller Bearings

In order to keep bearings working in a good condition, a minimum load must be imposed on the bearings, particularly on bearings working at high speeds, high accelerations, or with load direction changing frequently, because under these working conditions, inertial force of balls and cage and lubricant friction will have bad influence on the rotation of bearings, and detrimental sliding movement may be caused.
The minimum load of a spherical roller bearing can be obtained from£º
Fmin = 0.01 C0
When bearings are started at low ambient temperatures or in the condition that the viscosity of lubricant is very high, larger a minimum load is probably needed. Usually, the weight of bearing supporting parts plus the load on the bearing have been enough to over the minimum load. If the weight cannot be up to the minimum load, then extra radial load must be imposed on this type of bearing in order to meet the requirement of minimum load.
