This carriage forms the moving element of a six-row recirculating ball bearing and guideway assembly, riding on the rail with six load-bearing ball rows for contact on both sides of the carriage. It is built in the long design, giving an extended base length that increases the supported moment load compared to a standard carriage of the same profile. Net mass is 1.58 kg. The unit is manufactured to accuracy class G3, suitable for applications where a moderate level of running and positioning accuracy is required rather than the tightest tolerance grades. The six-row ball arrangement distributes load across multiple contact points, supporting even load transfer along the guideway during linear motion. As no equivalent references from other manufacturers are provided, this carriage should be ordered and matched strictly by the KWSE30-L-V1-G3 designation to ensure correct fit with the mating rail and carriage set.
