Capacité de charge statique C0
Lorsqu’un guidage sur rail profilé, en mouvement ou à l’arrêt, est soumis à des charges ou des chocs excessifs, une déformation locale durable se crée entre le chemin de roulement et les billes. Dès que cette déformation durable dépasse une certaine taille, elle perturbe le bon fonctionnement du guidage. La capacité de charge statique, selon sa définition fondamentale, est une charge statique provoquant une déformation durable de 0,0001 × diamètre de la bille au point de contact qui est le plus soumis aux charges. Les valeurs sont indiquées dans les tableaux pour chaque guidage sur rail profilé. À l’aide de ces tableaux, le constructeur peut sélectionner le guidage sur rail profilé adapté. La charge statique maximale à laquelle un guidage sur rail profilé est soumis ne doit pas dépasser la capacité de charge statique.
Couple statique autorisé M0
Le couple statique autorisé est le couple qui, dans une direction et des dimensions données, correspond à la plus grande charge statique possible des pièces mobiles. Le couple statique autorisé pour les systèmes de mouvement linéaire est défini dans trois directions : MX, MY et MZ.

Principle of operation of a linear guideway
A linear guideway makes it possible to move in a linear motion with rolling elements. The use of balls and rolls between the rail and block in a linear guideway makes precise linear movements possible.
Displacement resistance depending on lubrication condition
The displacement resistance of a carriage depends on many factors, e.g. load, temperature, lubricant (grease, fluid grease, oil), lubricant quantity, travel speed, series, size or the sealing system. A concrete specification of the displacement resistance is therefore only possible with defined general conditions. An essential factor here is the lubricant and the lubrication condition. Especially in freshly lubricated condition, the displacement resistance is clearly increased. However, after a running-in period of 15 metres, the displacement resistance is reduced again by approx. 50%.
Mechanical or manual chamfering
In the following video, you can see how chamfering edges on linear guideways works both mechanically and manually.
Linear guideway – grease lubrication via lubricating nipple
In the following video, you can see how a lubricating nipple adapter can be mounted on the carriage of a linear guideway. This reduces the effort for lubrication to a minimum. Lubricants basically reduce wear, protect the component from contamination and thus extend the service life. The lubricant is a constructional element and should therefore be taken into consideration when designing a machine. Like any rolling bearing, HIWIN linear guideways also require an adequate supply of lubricant. Both grease and oil lubrication are possible.
Long-time lubrication unit of a linear guideway
The long-time lubrication unit for linear guideways makes it possible to increase lubrication intervals many times over, thereby considerably reducing the number of maintenance intervals. If needed, up to two long-time lubrication unit can be installed per block.
Assembly and disassembly of cover caps
The cover caps are used to keep the mounting holes of the profile rails free of chips and dirt. In this video, we show you how to easily assemble and disassemble steel, brass or plastic cover caps.
