Linear shaft fi=20 H6

Product Description

Linear shaft h6 with a diameter of 20 mm - sold by the metre

This linear shaft with a diameter of 20 mm is a basic component of linear guides, and we sell it by the metre. Made of steel Cf53 (1.1213), induction hardened to 60-64 HRC and ground to tolerance h6 (ISO).

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.

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.

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 h6 mean for this shaft?

Tolerance h6 (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.

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.
