Linear shaft fi=25 H6 chrome-plated L=428

Product Description

Chrome-plated linear shaft fi=25 mm h7, length 428 mm

A fi=25 mm shaft with a fixed length of 428 mm works well where an exact dimension matters more than running metres. Core of steel Cf53 (1.1213) with a layer of technical chrome, made to tolerance h7 (ISO).

Technical data

Frequently asked questions

Which linear bearing fits this shaft?

Any linear bearing, plain bushing or carriage intended for a diameter of fi=25 mm - what matters is matching the diameter and tolerance h7, not the bearing manufacturer.

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=25 linear shafts used?

Linear shafts of this diameter are used in linear axes of CNC machines, production lines, manipulators, packaging machines, industrial automation feeders and positioning systems - where the linear guide has to carry higher loads.
