This carriage carries linear loads by recirculating ball elements along a profiled rail, allowing smooth motion with low friction resistance. The design KWVE25-B-V0-G4 has a net mass of 0.82 kg and is manufactured to accuracy class G4, providing defined positioning tolerances for the guideway assembly. The G4 accuracy class makes this carriage suitable for applications where moderate positioning precision is required, without the tighter tolerances demanded by higher accuracy classes. As a recirculating ball design, it supports continuous linear travel along the mating rail, with load capacity distributed through the ball recirculation path built into the carriage body. No interchange references are available for this part number, so identification and ordering should rely solely on the INA designation KWVE25-B-V0-G4.
