Spherical roller bearings have been working in the state (the eccentric shaft and the housing has a 2.5 degree angle, eccentricity) what is the impact on the bearing?
How can it have no effect? The self-aligning bearing, as its name implies, can work under eccentric conditions, but it does not mean that the working state is optimal in eccentric conditions. According to the ROMAX stress analysis, the maximum stress of the bearing is about 30% higher than the eccentricity of 2.5 degrees, and the service life drops by about 2 times. Only the impact of more ordinary bearings are much smaller, such as deep groove ball bearings, if eccentric 0.5 degrees, bearing life only 20% of the standard life! Therefore, even if the use of spherical roller bearings, the best small eccentric angle, improve the operation accuracy and the service life of the bearing!
No effect, this is the advantage of spherical roller bearing.
There is no effect, see the size series of bearings, spherical roller bearing structure characteristics are allowed to work in this state, allowed to work at a 2.5 degree angle aligning 232, 241 series, and other series of dimensions aligning angle will cause the roller raceway caused from stress concentration leads to early damage.
