Technical data

Frequently asked questions

Can I use any linear bearing with this shaft?

Yes, as long as the bearing or bushing is intended for a diameter of fi=40 mm. You choose the bearing type (ball, plain, linear carriage) according to the design of the mechanism.

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.

How much can the shaft bend over its length?

The permissible deviation from straightness is up to 0,5 mm per metre of length - this is the standard for precision linear shafts, regardless of diameter.

What does tolerance h7 mean for this shaft?

It is an ISO designation describing the tolerance zone of the outer diameter - h7 ensures an accurate, repeatable fit with the linear bearing.

Where are fi=40 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.
