High precision bearings for combined loads
All the fixing screw holes must be used. If a smaller number of
fixing screws is used, this will reduce the load carrying capacity of
the screw connections as well as the running accuracy and rigidity of
the bearing.
The rigidity values in the dimension tables of TPI 120, High Precision
Bearings for Combined Loads, and in Catalogue HR 1, Rolling
Bearings, are only valid if all the fixing holes are used.
In order to prevent unacceptable variations between the screw
tensioning forces, adhere exactly to the fixing sequence (tighten
the screws in a crosswise sequence).
