Product Description

Linear shaft h6 with a diameter of 12 mm - sold by the metre

A precision fi=12 mm shaft for linear axes and guides, priced per running metre. 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=12 mm - what matters is matching the diameter and tolerance h6, not the bearing manufacturer.

Does this shaft need lubrication or maintenance?

The shaft itself needs no lubrication, but in a damp environment it is worth protecting the surface with anti-corrosion oil - steel Cf53 is not corrosion resistant.

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.

Where are fi=12 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.
