After many years of discussing gearboxes with engineers, we have developed a questionnaire we use to ensure that all the necessary details of an application have been found. This is used, even if the engineer specifies our standard part number.
In most applications, conversations are needed to clarify the specifications before a quote is issued. All your specifications, both written and verbal, are included in a formal quote. Ondrives will supply a drawing or CAD.stp file for approval.
