Special Requirements

6.5 Corrosion Resistance

Corrosion protection is not just required in a cleanroom or vacuum. Medical,

laboratory or food applications demand corrosion-resistant steel, as used in all

MINI-X products.

6.6 Short Strokes

The effects of short strokes include point compression along the tracks and

inadequate lubrication. As a result, short strokes reduce the service life of the

guideway. This can only be reliably determined by means of experimentation.

6.6.1 Short Strokes with MINISLIDE

The stroke length of the guideway is so low that the rolling elements cannot pass

the position of the next rolling element. As a result, local wear marks form on the

tracks. Overstraining the tracks with short strokes leads to material damage which

inevitably leads to the loss of preload. The accuracy of the guideway can

consequently be reduced which can lead to premature failure.

Additionally, high-frequency strokes can break the lubricating film, further

exacerbating wear. With suitable lubricants and regular strokes along the entire

stroke length, better lubrication can be achieved, delaying the effects of material

wear.

6.6.2 Short Strokes with MINIRAIL and MINISCALE PLUS

In the starting position (1), only the ball bearings directly under load are lubricated.

Once the carriage moves to the right (2), a section of the ball bearings takes up the

lubricant via the guideway. Only once position 3 has been reached will all of the ball

bearings and all four corners of the ball recirculation be lubricated.

A short stroke is when the stroke of the carriage corresponds to less than twice its

length. This can lead to damage, particularly in the redirection unit. Regular

lubricating strokes along the entire stroke length at a minimum of twice the length

of the carriage ensure better lubricant distribution, protecting the guideway from

premature wear.

We recommend using LUBE-S long-term lubrication for short strokes.
