This carriage guides a linear rail through a four-row recirculating ball arrangement, providing load support across all four contact rows in a narrow carriage design. Net mass is 0.98 kg, and the unit is manufactured to accuracy class G3, giving defined running and positioning tolerances for the guideway assembly. The four-row ball arrangement distributes load evenly across the carriage width, supporting stable motion along the rail. The G3 accuracy class suits applications where consistent positioning repeatability is required. As a narrow-carriage design, it fits guideway installations where reduced carriage width is needed while retaining full four-row load-bearing contact.
