Use in dirt
Even the application under coarse dirt and sand is possible.
Particles are repelled from the contact surface by the
movement itself. Seals can be dispensed with due to the
dry operation. Dust and dirt cannot stick to grease or oil.

Surfaces
Hard-anodised surfaces are characterised by good wear
properties, high chemical resistance and a high degree of
hardness. It is a technical and not a decorative surface.
Colour alteration and slight cracking may occur, but do
not influence the resistance, the corrosion behaviour or
the sliding properties.
Eloxal stands for the electrolytic oxidation of aluminium.
This gives the CA rail profiles a silver/colourless surface
that is resistant to corrosion and wear. A lot of aluminium
profiles are also available as black anodised (AR anti-reflect) Lubrication-free and resistant to dust and dirt
versions. Both variants (CA/AR) are suitable for applications
that require consistent colouring.
Cutting surfaces and machined surfaces are uncoated.

Extreme application conditions in the offshore industry

Chemical resistance
iglidur J is resistant to weak acids, diluted alkalis as well
®
as to fuels and all kinds of lubricants. The intensive cleaning
of machines with standard commercial cleaning agents,
even in the food sector, is therefore not a problem for the
guides. For applications in environments with aggressive
chemicals, it is recommended to use drylin R linear
®
bearings equipped with iglidur X liners. The resistance of
®
linear bearing systems is equally dependent on the counter
partner. The most chemical-resistant option can be a high-
alloyed steel stainless steel shaft, for instance high grade
Filling machine, Krones AG, Rosenheim (Germany) steel (AISI 440B), or alternatively the use of soft VA steels
(e.g. (AISI 316Ti).
