Minimum information for a useful quotation
- Drawing, CAD data or both mating samples
- Module or diametral pitch, tooth counts and ratio
- Pressure angle, shaft angle, spiral angle and hand where applicable
- Mounting distance, backlash, bore, keyway or spline and datum details
- Material, heat treatment, hardness and case depth
- Speed, torque, power, duty cycle, rotation and lubrication
- Quantity, annual demand and delivery location
- Inspection reports, certificates and third-party requirements
For replacement and failure enquiries
Include photographs of both members, housing and bearings; machine make and model; failure history; lubricant; operating hours; previous repairs; and the shutdown date.
Why complete information matters
It reduces assumptions, avoids quoting the wrong geometry, improves delivery planning and makes the inspection and acceptance scope clear.
Frequently asked questions
Can rfq information checklist be developed from an existing sample?
A sample can support dimensional study, but the most reliable route also includes the mating member, shaft angle, mounting information, speed, torque, material or hardness information and failure history.
What information is required for quotation?
Provide a dimensioned drawing or sample, quantity, module or diametral pitch, tooth counts, pressure angle, spiral hand where applicable, ratio, material, heat treatment, accuracy requirement and expected duty.
Can one member be replaced without the mating gear or pinion?
It may be possible after inspection, but a matched-pair approach is normally preferred because tooth contact, backlash and mounting are interdependent.
How is delivery time determined?
Delivery depends on geometry, quantity, material availability, tooling, heat treatment, finishing, inspection scope and technical approval.
