This carriage runs on four rows of recirculating balls, giving it contact on four raceways for load support from multiple directions. The expanded, narrow-width design (KWVE25-B-ES-V1-G3) keeps the mounting footprint compact while maintaining full raceway geometry. Net mass is 0.504 kg, and the unit is manufactured to accuracy class G3. The four-row ball arrangement allows the carriage to take up radial, reverse radial and lateral loads from a single guideway assembly, which is useful where the mounting structure cannot provide additional support in more than one plane. Accuracy class G3 defines the dimensional and running tolerances of the carriage, so it should be matched with a guideway and adjoining carriages of the same accuracy class to keep running parallelism within specification. The narrow design suits installations where lateral space along the guideway is limited but full four-row load capacity is still required.
