Technical data

Frequently asked questions

Which linear bearing fits this shaft?

Any linear bearing, plain bushing or carriage intended for a diameter of fi=20 mm - what matters is matching the diameter and tolerance h6, not the bearing manufacturer.

How does the stainless version differ from the standard one?

The stainless version is made of steel X46Cr13 - it withstands contact with water and moisture without rusting, unlike steel Cf53, which has to be protected with oil in such conditions.

What does tolerance h6 mean for this shaft?

It is an ISO designation describing the tolerance zone of the outer diameter - h6 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.
