Static load rating C0
If a linear guideway system is subjected to excessive loads or impacts during movement or at a standstill, localised permanent deformation occurs between the track and balls. As soon as this permanent deformation exceeds a certain level, it affects smooth operation of the guideway. According to its basic definition, the static load rating corresponds to a static load that causes permanent deformation of 0.0001 × ball diameter at the contact point that is loaded the most. The values are given in the tables for each linear guideway system. Using these tables, the designer can select a suitable linear guideway system. The maximum static load to which a linear guideway system is subjected must not exceed the static load rating.
Permissible static moment M0
The permissible static moment is the moment which, in a defined direction and size, corresponds to the maximum possible load on the moving parts by the basic static load rating. The permissible static moment is defined for linear motion systems for three directions: MX, MY and MZ.
Long-time lubrication unit E2
The long-time lubrication unit considerably increases lubrication intervals. Depending on the application and ambient conditions, it can achieve lifetime lubrication. It also considerably reduces lubricant consumption, as only the required quantity of lubricant is applied. The compact construction and special design allows the block to be fitted in any position without impairing the lubrication function. The long-time lubrication unit can be used at ambient temperatures of -10°C to +60°C.

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.
