This carriage is the moving element of a linear guidance system, running on four rows of recirculating balls to carry load and moment forces from the rail. The design is a high, narrow, and long carriage body, giving it an extended contact length along the rail. Net mass of the carriage is 2.464 kg, and it is manufactured to accuracy class G3. The four-row ball arrangement allows the carriage to take up loads from multiple directions and provides stable guidance under combined load conditions. Accuracy class G3 sets the dimensional and running tolerances of the carriage relative to the rail, which is a factor to consider when matching it with other carriages or rails in the same system to keep consistent alignment across multiple carriages.
