Welding positioner (Cantilever-mounted 2-axis type)
SPT series
SPT
Superior movement achieved with zero-backlash technologySPT series models come with Sankyo’s RollerDrive zero-backlash reducer mechanism, enabling faithful operation with no disruptions in behavior in response to outside forces. RollerDrive’s good settling performance enables takt time reduction. Torque is transmitted through rolling contact while maintaining the proper precompression state, preventing drops in accuracy even during extended use.Commercially available servo motors can be mounted.

*1 The allowable moment load varies depending on the load weight. Please refer to the allowable moment diagrams for more information.*2 Internal moment of inertia at the input shaft depends on the SP attachment code. For details, see the attachment code selection table on page 7 of the SP catalog.*3 Recommended motor power value is reference only. It depends on the operating conditions.
▼ The thin welding positioner body enables a compact overall system
configuration.
▼ The large-diameter hollow bore makes wiring and line installation easy.
▼ The cam mechanism creates outstanding settling performance, and
provides the rigidity needed to withstand emergency stops.
