Product description
Corrosion resistance and conditions of use
Ball Guide Rails Resist NR II made of corrosion-resistant steel according to DIN EN 10088. Ball Guide Rails Resist NR II are especially suited for use in wet environments. These are also suitable for use at relative humidities above 70% and temperatures exceeding 30°C.
Since no additional corrosion protection is required, Ball Guide Rails Resist NR II are especially suitable for use in the semiconductor industry, machine tool industry, and especially where corrosion protection is required. Other possible areas of application include the packaging industry and areas of the food industry.
Ball Guide Rails with corrosion-resistant coatings can also be replaced by Ball Guide Rails Resist NR II.
Please consult us for special applications.
