Ball bearing guideway assemblies
The ball bearing guideway assembly is the most variable type of profile rail guides and is available as a 2-row, 4-row and 6-row unit. The 2-row variant is the most economical for use in low and medium capacity range. It is preferred when there are lower demands on the strength and stiffness of the guide. The 4-row version, however, is highly stable and is used when not only the dynamics but also the max. carrying capacity and stiffness plays a role. In addition, this variant is available with a plastic spacer carriage, whereby the guide runs much quieter. The 6-row version is the stiffest and most viable form of ball-guided units.
