Linear shaft fi=20 H6 supported

Product Description

Supported linear shaft fi=20 mm h6 - sold by the metre

This fi=20 mm linear shaft is mounted on a support along its entire length, so it does not bend even over long spans. 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?

Supported shafts are used with open linear bearings (with a slot for the support) with a diameter of fi=20 mm - closed bearings cannot pass the support mounting.

How does a supported shaft differ from a standard shaft?

A supported shaft is fixed to the base along its entire length, so it does not bend under load even over long spans. A standard shaft is fixed only at its ends.

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.
