drylin® W 免上油線性系統雙軌，WSPC

The carbon profile rail is particularly light and tensile
The carbon profile rail WSPC is 70% lighter than linear rails made of aluminium or stainless steel. Especially in aircraft construction or the automotive industry the drylin® W carbon rail with square profile is used. The solid plastic carriage WWPL-06-30-06 made of an iglidur material was developed specifically for the carbon rail and has best coefficient of friction and wear. 
The X-ray transparency is another advantage of the carbon fibre. So the material is often used in medical or measurement technology.
