Linear guides
Linear guides form the basis of a linear bearing. They usually take the form of a metal strip with fixing holes and a raceway for the rolling elements of the bearing cages. The raceway can be flat or profiled. The main task of linear guides is to transfer pressure from the machine parts to which they are bolted to the rolling elements and to provide the rolling elements with the best possible conditions for correct operation.

General information
CR3-type ceramic linear guides are dimensionally compatible with R-type steel guides but they offer several advantages: they are lighter, non-magnetic, and anti-electrostatic. Like R-type linear guides, they also feature a V-shaped profile, allowing for the use of RRK, AA, RKK, or SRK cages with rolling elements made from bearing steel, stainless steel, or ceramics (Si₃N₄, Al₂O₃, ZrO₂).
CR linear guideways are made from technical ceramic ZrO₂ with a hardness > 1200 HV.
