This carriage guides a linear motion system on four rows of recirculating balls, distributing load across the rail profile and allowing smooth travel under combined loading directions. Built as a high, narrow carriage version (B-H design), it carries a net mass of 1.09 kg per unit and is manufactured to accuracy class G3, giving defined tolerances on running parallelism and dimensional consistency for precise positioning tasks. The four-row ball arrangement allows the carriage to take up loads from multiple directions with balanced rigidity, which suits applications requiring stable guidance along the full length of the rail. Accuracy class G3 supports installations where moderate positioning precision is required without the tighter tolerances of higher classes, making mounting and alignment straightforward while maintaining consistent motion quality across the travel length.
