What is the difference between a supported ball screw and a double-ended supported ball screw

The main difference between support-type roller screws and double-end supported roller screws lies in their supporting methods and applicable scenarios.

Support-type roller screws have a support device between the screw and the nut to improve their rigidity and load-bearing capacity. Support-type roller screws usually have a support device on one end, while the other end is supported by other components. Support-type roller screws are suitable for scenarios with high loads and speeds, such as machine tool processing and automated production lines.

Double-end supported roller screws, on the other hand, have support devices at both ends to further improve their rigidity and load-bearing capacity. Double-end supported roller screws are more stable than support-type roller screws and can withstand bidirectional loads. Double-end supported roller screws are suitable for higher-demand mechanical equipment and automated production lines.

It should be noted that the manufacturing process and cost of support-type and double-end supported roller screws are relatively high, so their applicability and economic benefits should be considered when selecting them for use.
