HIWIN coating HICOAT CZS
HICOAT CZS is a very thin zinc coating that offers a very good corrosion protection, even on radii and chamfers. Smaller bare parts stay protected by the cathodic corrosion protection. Compared with uncoated pieces this leads to significantly higher periods of use. The CZS coating is available for the HG, EG and CG series. Further information can be found in the catalogue "Linear Guideways" under chapter "HIWIN coatings for linear guideways".
HIWIN coating HICOAT CTS
HICOAT CTS is a thin layer chrome coating that offers good corrosion protection and a very high wear protection. The high wear protection results from the extraordinary hardness of the coating. The CTS coating is free of Cr(VI) and suitable for use in food stuffs. It is available for the HG, EG, CG and WE series. Further information can be found in the catalogue "Linear Guideways" under chapter "HIWIN coatings for linear guideways".

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.
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.
