drylin® - Special advantages
Corrosion behavior
The low humidity absorption of iglide® J, J200 and T500 permits even underwater applications. The application of stainless steel or anodized aluminum shafts provide for a corrosion-resistant guide system. Anodized aluminum is resistant to chemically neutral substances in the range pH 2 to 7.For special cases of application, separate tests are recommended for coated aluminum sample parts for that specific application.
Operating temperatures
Gliding elements made of iglide® J and J200 can be used in the temperature range between -40 and +194°F (-40 to +90°C). In applications with aluminum shafts and/or rails, distinctly higher loads and speeds can be attained due to the excellent heat conductivity. Gliding elements made of iglide® T500 can be used in the range of -148°F to +482°F (-100°C to +250°C).Resistance to chemicals
iglide® 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 thus not a problem for the guides.For applications in environments with extreme chemical loads, the application of the drylin® R bearings equipped with iglide® T500 liners is recommended.
The resistance of linear bearing systems is equally dependent on the counter partner. As a partner most resistant to chemicals, a high-alloyed stainless steel is offered, for instance X105 CrMo 17 (1.4125), or alternatively the use of soft VA steels (e.g. 1.4571).
