This carriage forms the moving element of a linear recirculating ball bearing and guideway assembly, running on the matching profile rail. The wide design of the KWVE20-W-V2-G3 carriage provides an enlarged support base, giving better load distribution across the ball tracks. Net mass of the carriage is 0.5 kg, and it is manufactured to accuracy class G3. Accuracy class G3 sets the dimensional and running tolerances of the carriage, which determines the positioning precision achievable in the guideway assembly. The wide carriage layout increases stability against tilting moments compared to a standard-width carriage of the same rail size. As a recirculating ball design, the carriage recirculates the balls internally, allowing continuous linear travel along the rail without a stroke limit imposed by the ball set itself.
