This carriage guides linear motion along a profiled rail using a four-row, full-complement ball set, eliminating the need for a cage and increasing the number of load-bearing balls in contact. The long carriage design (L) provides an extended mounting surface and load-bearing length compared to the standard version. Net mass is 1.832 kg, and the unit is manufactured to accuracy class G3. The four-row arrangement allows the carriage to take up loads from multiple directions, suiting applications where guidance must handle forces acting from more than one side. Accuracy class G3 defines the permissible tolerances for parallelism and dimensional accuracy relative to the rail, which should be matched to the rail of the same class for correct system behavior. The full complement ball design increases load-carrying capacity per unit length but requires attention to lubrication intervals, as the absence of a cage means balls are in continuous mutual contact during travel.
