The figures listed in the L, M and H columns for
stiffness, limiting speeds and drag torque are based on the L (Light), M (Medium) and H (Heavy)
preload values given in this table.
* Abutment diameters are suitable for both sides of the bearing
** Preload, axial stiffness and
limiting speeds are for pairs of bearings mounted either back-to-back or
face-to-face |
