This carriage guides linear motion by recirculating ball bearings running along a matched guideway, allowing continuous travel with rolling contact rather than sliding friction. The wide carriage design of the KWVE20-W-V1-G3 increases the supported span between the ball tracks, improving stability under load and resistance to tilting moments. Net mass is 0.5 kg, and the unit is manufactured to accuracy class G3. The G3 accuracy class defines tight tolerances on running parallelism and dimensional consistency, making this carriage suitable for applications requiring precise, repeatable positioning along the guideway. As a recirculating ball design, it maintains a closed loop of rolling elements, which sustains smooth motion over the full length of travel without the need to replace balls after each stroke. Proper lubrication of the ball tracks is required to maintain the rated accuracy and running smoothness over the carriage's service life.
