Technical data

Frequently asked questions

Which linear bearing fits this shaft?

Any linear bearing, plain bushing or carriage intended for a diameter of fi=30 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.

Does this shaft need lubrication or maintenance?

The chrome coating protects the surface, but with prolonged exposure to moisture it is worth wiping it with oil. Lubrication is usually needed by the linear bearing, not by the shaft itself.

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.

Where are fi=30 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.
