spherical roller bearings specified in the catalog is defined as follows. Spherical roller bearings are dedicated to extremely severe applications and must support high loads, severe misalignment, contaminated environments, shocks, and vibrations. Roller bearings, known as rolling-element bearings, are similar to ball bearings in that they are designed to carry a load while minimizing friction , As opposed to ball bearings, roller bearings have barrel-shaped rolling elements instead of spherical balls. They can be designed to have cylindrical or tapered bores for mounting with or without a sleeve adapter. You can find further information here on mounting of the selected types. Spherical-Roller Bearings Two rows of rollers give these bearings dynamic radial load capacities over five times higher than comparably sized tapered-roller bearings. They are capable of supporting heavier loads than similarly sized ball bearings but cannot handle as high of speeds as ball bearings.
