Linear shaft fi=8 H6

Product Description

Linear shaft fi=8 mm, tolerance h6, by the metre

This linear shaft with a diameter of 8 mm is a basic component of linear guides, and we sell it by the metre. Material: steel Cf53 (1.1213), induction-hardened surface (60-64 HRC), tolerance h6 (ISO).

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=8 mm. You choose the bearing type (ball, plain, linear carriage) according to the design of the mechanism.

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.

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.

Where are fi=8 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.
