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.
