Carries and guides linear motion along a rail using a four-row recirculating ball arrangement, distributing load across all four rows for stable travel under combined loading directions. The carriage is built in the narrow, long design, giving an extended contact length on the rail while keeping a slim cross-section. Net mass of the carriage is 0.898 kg. The four-row ball arrangement allows the carriage to take up forces from multiple directions simultaneously, which keeps guidance stable along the rail. The elongated body length increases the supported contact area, helping to distribute load more evenly along the direction of travel and reducing the effect of local load peaks. This construction suits applications where a compact width is required together with a longer guiding surface on the carriage itself.
