Linear shaft fi=25 H6 L=350

Product Description

Linear shaft fi=25 mm h6 with a fixed length of 350 mm

A fi=25 mm shaft with a fixed length of 350 mm works well where an exact dimension matters more than running metres. Made of steel Cf53 (1.1213), induction hardened to 60-64 HRC and ground to tolerance h6 (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 h6, not the bearing manufacturer.

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.

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=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.
