Linear shaft fi=25 H6 chrome-plated L=210

Product Description

Linear shaft with chrome coating 25 mm, length 210 mm

A fi=25 mm shaft with a fixed length of 210 mm works well where an exact dimension matters more than running metres. Material: steel Cf53 (1.1213) with chrome coating, tolerance h7 (ISO) - the coating increases the surface resistance to wear and corrosion.

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=25 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.

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?

Tolerance h7 (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=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.
