This carriage runs on a linear guideway using four rows of recirculating balls, giving the design the ability to carry loads and moments from multiple directions through a single carriage body. The short carriage version KWVE15-B-EC-V1-G3 weighs 0.145 kg and is manufactured to accuracy class G3, with an expanded interchangeability that allows mounting on rails from other sources built to the same dimensional standard. The four-row ball arrangement distributes load across the carriage, supporting stable guidance under combined radial and moment loading. Accuracy class G3 sets the running and parallelism tolerances suitable for standard positioning tasks. As a short carriage, it fits applications where axial installation length is limited while still requiring balanced load distribution across all four raceways.
