This carriage runs on a linear guideway system using four rows of recirculating balls, giving it a narrow design suited for compact rail installations. Symbol KWVE15-B-S-V0-G3 refers to the narrow carriage version, with a net mass of 0.166 kg and manufactured to accuracy class G3. The four-row ball arrangement provides load-bearing capacity in multiple directions, making the carriage suitable for guided linear motion where consistent positioning accuracy is required. Accuracy class G3 supports applications where moderate precision in travel and alignment is needed, while the narrow carriage width allows installation where space along the guideway is limited.
