This carriage guides linear motion along a profiled rail using four rows of recirculating balls, providing load support from multiple directions within a single carriage body. The design is a high, narrow, long configuration, giving an extended contact length and increased carriage height relative to its width. Net mass of the carriage is 4.45 kg. Accuracy is manufactured to class G3, suitable for guideway assemblies where standard positioning accuracy is required rather than precision-grade tolerances. The four-row ball arrangement allows the carriage to take up loads from several directions, which is a direct result of the recirculating ball raceway geometry. As a component of the KWVE45-B-HL-V1-G3 system, it is intended to be paired with the corresponding profiled rail to form a complete linear guideway.
