Misalignment Problems in Cylindrical Roller Bearings 700559

In the application of cylindrical roller radial bearings where cumulative assembly tolerances or load deflection insure a significant skewness between inner and outer race center lines, careful design and manufacturing methods are required to provide reliable performance. In addition, when the composite problems become severe, lubrication and retainer design require extra attention. Arbitrary application of standard catalog bearings often leads to disappointing performance.
Misalignment effects can be noted in shortened fatigue life, extreme wear rates, and excessive operating temperatures. To insure against these detrimental results, more extensive analytical design methods must be employed and a more detailed understanding of the application must be developed.
Though not always appreciated, cylindrical roller radial bearings are capable of running with significant misalignment and offer economical rewards to the manufacturer when the design is properly worked out.
