This carriage guides a linear system along a profiled rail through four rows of recirculating balls, distributing load across all raceways for stable motion under combined radial and moment loads. The short carriage design (KWVE20-B-EC-V1-G3) has a net mass of 0.25 kg and is built to accuracy class G3, giving predictable running behavior without requiring high-precision alignment during installation. The four-row ball arrangement allows the carriage to take load from multiple directions simultaneously, which is useful where the guide must resist tilting moments as well as straight radial forces. Accuracy class G3 places it in the standard precision range, suitable for applications where moderate positioning accuracy is sufficient rather than high-precision positioning tasks. As a short-type carriage, it offers a compact mounting length, which should be checked against the load and moment requirements of the specific guide rail installation before selection.
