igus has developed a stainless steel version of its DryLin W linear guide especially for corrosive enviroments. DryLin W Stainless is designed principally for the food processing and packaging industries and for chemically exposed or underwater applications. The rails are made of V4A high-grade steel (316 Ti). This means the guides not only offer maximum corrosion resistance, but they also withstand many different chemicals and are resistant to temperatures up to 250 °C. The linear system needs no lubrication and therefore does not require any maintenance during normal operation.
The linear bearings are offered with the option of running on iglidur J or iglidur X polymer bearings. iglidur J is well-known for its minimal wear, chemical-resistance and vibration-damping properties. The high performance polymer also absorbs very little moisture. iglidur X also has these traits, but is additionally pressure-resistant, even under high-temperatures.
The new stainless steel guides are available as individual single rails with a diameter of 20 mm, or as a double rail (10 mm). Carriage size and the space between the rails can also be varied to suit the application.
