(1) The rigidity values in this table indicate spring constants obtained from the load and elastic displacement under a preload of 10% of the basic dynamic load rating Ca, and an axial load Fa that is three times that of the preload Fa0. As these values do not take into account the rigidity of the parts involved in the
nut installation, take 80% of the values given in this table as a general guideline.

If the preload Fa0 differs from 0.1 Ca, the rigidity KN can be calculated using the following equation:

Fa0
KN = K • ------- 1/3 • 0.8
0.1 Ca

If the ballscrew is not preloaded, please consult our technical department for the rigidity value.

Material
All steel construction except end wipers in Nitrile Rubber.
Single nut according to DIN 69051 (1989) with flange form B.

Other Info.
Max. running temperature 80°C. Preload by ball selection (G0 pre-loaded) Fao = 0.02Ca.
Precision accuracy Cp5 23µm/300mm (Cp3 P.O.A.). ISO 3408-3
Prices for longer lengths on application.
