This carriage runs on a linear guideway using a four-row full complement ball set, giving contact on all sides for load support in radial, reverse-radial, and lateral directions. The long carriage design of KWVE20-B-L-V2-G3 provides an extended mounting surface and increased moment load capacity compared to standard-length carriages. Net mass is 0.626 kg, and the unit is manufactured to accuracy class G3. The full complement ball arrangement, without a cage, allows a higher ball count within the carriage, increasing load capacity and stiffness for a given size. The G3 accuracy class suits applications requiring standard positioning accuracy and running parallelism, while the extended carriage length improves stability and evenly distributes load over a longer contact area along the guideway.
