Roller bearings are used in all main shaft and auxiliary drive shaft applications to support pure radial load, and allow for axial shaft elongation due to temperature changes with no additional load effect on the bearing.
accommodating
heavy radial loads, and axial loads in both directions;
suitable for low- or
medium-speed applications involving heavy or impact loading;
accommodating errors in housing
assembly and misalignments between the inner and outer rings;
automatically corrected to
reduce excessive force to bearings;
