## Description

The units are designed for linear motion guideways with long travel of moving assemblies at speeds of up to 10 m/min.
Guideways with roller units offer high rigidity, low motion resistance (reduced friction coefficient 0.002-0.004), high positioning accuracy, no stick-slip at low feeds, and long service life under intensive operation at higher speeds.
The unit consists of a rigid thin guide around which rolling elements (rollers) circulate along a closed path. The rollers are kept from falling out by cages and springs.
