Technical data

Frequently asked questions

Which linear bearing fits this shaft?

Any linear bearing, plain bushing or carriage intended for a diameter of fi=70 mm - what matters is matching the diameter and tolerance h7, not the bearing manufacturer.

How does the chrome-plated version differ from the standard one?

The base material is the same (steel Cf53), but the shaft has a chrome coating and is made to tolerance h7 instead of h6 - this is worth taking into account when selecting the fit with the bearing.

What does tolerance h7 mean for this shaft?

Tolerance h7 (ISO) defines the permissible deviation of the outer diameter of the shaft - the smaller the deviation, the more accurate the fit with the linear bearing.

Can this shaft be used for rotary motion?

A linear shaft is designed for linear (sliding) motion together with a linear bearing or bushing - it is not a drive shaft transmitting torque, such as a splined shaft.

Where are fi=70 linear shafts used?

Large-diameter linear shafts are used in heavy linear axes of machines, presses, production lines, manipulators and internal transport equipment - wherever the linear guide carries high loads.
