FAQ

Q1: What does the designation “V3” mean for this bearing unit?
A1: “V3” identifies a high preload level in the carriage assembly. Preload reduces internal clearance, increases stiffness and improves positional accuracy—especially important for precision linear motion.

Q2: What is the significance of accuracy class “G2”?
A2: Accuracy class G2 indicates tighter manufacturing tolerances compared to standard options. Such a classification ensures higher repeatability, smoother guidance and reduced play in motion systems.

Q3: Can this unit be mounted in a bearing housing or as a bearing unit?
A3: Yes—this linear bearing carriage is compatible with standard guideways and can be mounted within a bearing housing or used as a bearing unit, facilitating maintenance and component replacement in industrial assemblies.

Q4: In which applications is this unit most useful?
A4: Typical applications include CNC machines, automated assembly lines, robotics systems, material-handling conveyors and other industrial equipment where high durability, precision motion and repeatability are essential.
