This carriage forms the moving element of a linear guidance system, running on a profiled rail through four rows of full complement balls that carry load without a cage. The design is narrow and short, giving a compact footprint of 0.11 kg net mass, and it is manufactured to accuracy class G3. The full complement ball arrangement across four rows allows the carriage to take up loads from multiple directions and transmit them evenly onto the rail, which supports stable guidance under combined loading conditions. Accuracy class G3 defines the permissible tolerances for running parallelism and dimensional consistency, making this carriage suitable for applications where a defined positioning accuracy along the guide rail is required. The compact narrow-short design suits installations with limited mounting space along the axis of travel.
