This carriage is the moving element of a linear guideway system, riding on six rows of recirculating balls that transfer load between the carriage body and the rail. Net mass is 0.881 kg, and the long body version extends the load-carrying length compared to a standard-length carriage, giving a larger contact area along the rail. Accuracy class G3 sets the dimensional and running tolerances of the carriage. Matching carriages and rails of the same accuracy class keeps preload and travel behavior consistent across the assembly, which matters wherever positioning accuracy along the guideway must be maintained. KWSE25-L-V2-G3 should be paired only with components of the corresponding rail and accuracy grade.
