Traceability is documented and maintained at every step in the manufacturing and service process in our specialized inventory-tracking software program, from the material certifications of the raw materials used, through machining, assembly and delivery, hours in operation, refurbishment records and even its anticipated length of service. Before we deliver a motor, every part is thoroughly inspected to ensure that it meets our precise specifications. The complete record of the part is available for customer review.
