New drylin® W econ rail profiles

Linear rails made of aluminium with clear anodised coating (CA=clear anodised) are now available for the drylin® W profile guide 10,16 and 20 with round shape. In price-sensitive environments and in applications where durability, chemical resistance and precision are not top priorities, the new econ CA rails offer a real alternative. Due to their consistent silver colour, econ CA profiles are also ideally suited for use as visible parts, for example in furniture construction.


  • Consistent silver rail finish
  • "econ" cost-effective and corrosion-free due to clear anodised coating
  • Available as drylin® W single rails and double rails in installation sizes 10/16/20 (round)
  • Suitable for all drylin® W single bearing housings and linear carriages
  • Lifelong rattle-free through combination with pre-loaded drylin® W linear bearings series WJ200UM-01-Pxx
  • Individual bearing clearance adjustment by using WJ200UME-01 bearing housings

Clear anodised rails in installation sizes 10, 16 & 20

Coefficients of friction of drylin films on anodised rails

We developed the linear rails with clear anodised finish for this purpose

The clear anodising provides the rails with a consistent silver appearance. In every rail. Thus they serve well whenever they are used as visible parts.   We recommend using the new clear anodised rails with adjustable or pre-loaded igus® linear bearings.
