Footnotes
Maximum length of single-piece guideways; longer guideways are supplied as several segments.
Indicate hole pattern and end spacings aR, aL when ordering.
The stated torques represent maximum values for the secure transmission of forces in vibration-free, quasistatic applications (S0 = 1). We recommend that the tightening torques for the screw connection of the adjacent construction should be determined at the customer under the conditions specific to the application and operation, observing the information in VDI Guideline 2230 Part 1 (2015) and the information in this description.
Closing plugs must be ordered separately.
Linear roller bearings.
