Warranty Support Starts With the Correct Part Record.
Returns and warranty questions are reviewed by part number, confirmed condition, shipment record and technical evidence.
Warranty & Returns
Do not send parts back before our team reviews the case.
Automation parts need traceable handling. Before any return or warranty action, our team checks the original inquiry, quoted condition, shipment details, visible markings and your application information.
