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.

Can I shorten this shaft myself?

We do not recommend cutting it yourself - it can damage the hardened surface and affect the straightness of the shaft. It is best to install the shaft in the length supplied.

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.

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.
