This carriage guides linear motion along a profile rail using a four-row, full complement ball set, giving contact on all rows without a ball cage. The long carriage design (L) provides an extended mounting surface and load-bearing length compared to the standard version. Net mass is 1.023 kg, and the unit is manufactured to accuracy class G3. The four-row full complement ball arrangement increases the number of load-carrying balls in contact, supporting higher rigidity and load capacity within the carriage envelope. Accuracy class G3 defines the permissible tolerances for running parallelism and dimensional accuracy, making this carriage suitable for applications where consistent positioning along the rail is required. The long carriage variant offers additional support length, which is relevant where extended mounting surface or increased moment load capacity is needed compared to the short version.
