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=20 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.

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.

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=20 linear shafts used?

Linear shafts of this diameter are most often used in CNC sliding tables, linear axes of Cartesian robots, 3D printers, plotters, packaging machines, industrial automation feeders and measuring devices - wherever precise, repeatable linear motion is needed.
