Choose the quotation route that matches the evidence you have
A controlled drawing is the fastest basis for a firm custom gear quote. A sample can support reverse engineering but requires wear and mating-condition review. A performance target needs engineering definition before price and lead time can be fixed. Each route still needs quantity, material, heat treatment, inspection and delivery scope.
Use the PairGears custom gear RFQ information guide to prepare the available evidence.
Drawing-based quote
Send controlled 2D/3D files, tooth data, datums, tolerances and specifications. Missing items should be listed as written assumptions.
Sample-based quote
Provide the sample, photos, key dimensions, OEM number and mating information. Worn parts may not represent the original geometry.
Performance-based quote
Define torque, speed, duty cycle, life, noise, space, environment and interfaces. Engineering work precedes a production quote.
What changes quotation confidence?
- Drawing revision and completeness
- Sample condition and access to mating parts
- Known material, hardness and heat treatment
- Prototype, batch and annual quantities
- Required reports, packaging and Incoterms
