CF6.15.18 is a length of 18 millimeters for a series of bearings made by Igus. This series is made up of drylin® radial bearings, which are a plain bearing system, meaning there is no rolling elements. The bearing is comprised of an outer plastic or metal housing that contains an inner drylin® material such as acetal, fluoropolymer, or aluminum, which reduces friction and noise due to the low coefficient of friction, and prevents corrosion and wear as the material itself is self-lubricating. The bearing is manufactured to the highest standards, and provides high temperatures and corrosion resistance. The CF6.15.18 is suitable for a variety of applications, including linear and circular motions, positioning, and heavy loads.
