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. (see chapter 8.1). Stroke movement of the ball bearings Wear marks and broken lubricating film
