Ball screws - Static and dynamic axial load ratings and operational life not-for-sale BS EN 755-4:2008 includes some

BS EN 755-4:2008 includes some technical changes with respect to BS EN 755-4:1995

The specific values declared are given in the context of a specific declaration scheme and supported with details of the relevant life cycle stage and details of its scenario

Typical applications are corrosion fatigue tests and selected fretting and wear tests

This part of ISO 140 is based on measurements with artificial raindrops under controlled conditions using a water tank in a laboratory test facility in which flanking sound transmission is suppressed

Ball screws - Static and dynamic axial load ratings and operational life not-for-sale BS EN 755-4:2008 includes some1 Scope This part of ISO 3408 specifies the calculation schemes for static and dynamic load ratings, and operational life, in order to obtain comparable values for the design and use of ball screws. NOTE The calculations have been based primarily on publications by Prof. G. Lundberg and A. Palmgren Acta Politechnica, mech. Eng. series Vol. I, No. 3, Stockholm, Sweden. Part 7, 1947. This part of ISO 3408 is applicable under the following preconditions:
