Product overview
Custom Spur Gear manufacturing starts with confirmed technical requirements.
Review the gear pair, assembly conditions, drawing requirements, specification checks, and inspection points before requesting a quotation.
A custom spur gear must match both the mating gear and the surrounding shaft and housing. ZhongYi reviews buyer drawings, samples, or confirmed technical specifications for straight-tooth external gears used on parallel shafts. The quotation review can cover module or diametral pitch, pressure angle, tooth count, face width, bore, hub, keyway, material, heat treatment, tooth finishing, backlash, and inspection requirements. For replacement gears, a worn sample is useful but may not preserve the original tooth thickness or profile. Mating-gear data, center distance, shaft details, and assembly photographs help engineers distinguish the intended geometry from wear. Exact tolerances, accuracy grades, hardness, and process routes are confirmed against the approved drawing rather than treated as universal product claims.
Tooth Accuracy DIN 5-7 / AGMA 11-13
Tooth Finishing CNC Ground (Ra โค0.4ยตm)
Hardness Grade Carburized 58-62 HRC

Selection guidance
How to specify a custom spur gear for quotation.
Use application and mating-component data to confirm geometry, materials, mounting details, and the acceptance plan.
Begin with the gear pair, not the outside diameter. Confirm module or DP, pressure angle, tooth count, center distance, mating-gear data, and required backlash. Then define how the gear locates on the shaft: bore fit, keyway, spline, interference fit, locking element, or integral pinion shaft. Load, speed, duty cycle, lubrication, temperature, contamination, noise expectations, and service life influence the material, heat treatment, and tooth-finishing route. Include the drawing revision, quantity, acceptance criteria, and any required inspection report in the RFQ.

All products can be custom manufactured from 2D/3D CAD drawings or physical samples.
Quality Control & Inspection Matrix
Engineering Evidence & 100% Inspection for Custom Spur Gear.
Overseas procurement teams require verifiable technical data, not unsupported claims. Every production batch at ZhongYi is inspected against approved CAD blueprints and international standards (DIN, AGMA, ISO).
Component-Specific Quality Focus:
Inspection should follow the buyer-approved technical file. Depending on the drawing and purchase requirement, checkpoints may include blank dimensions, bore and face runout, tooth thickness, pitch-related characteristics, hardness, surface condition, and fit with the mating gear. ZhongYi does not assign an unsupported accuracy grade or performance rating. Buyers should identify critical characteristics and required records before production so quotation, manufacturing, and acceptance use the same criteria.

Technical FAQ
Common questions before ordering custom spur gear products.
Critical specifications are confirmed against final drawings before production.
What information is needed for a custom spur gear quote? โผ
Provide a 2D or 3D drawing when available, or a sample with module or DP, pressure angle, tooth count, face width, bore, hub, keyway, material, heat treatment, quantity, and operating conditions. Mating-gear and center-distance data reduce replacement risk.
Can a spur gear be manufactured from a worn sample? โผ
A sample can support feasibility review, but wear may hide the original profile and tooth thickness. Supplying the mating gear, shaft dimensions, housing center distance, and any historical drawing helps reconstruct the intended component.
Should the teeth be cut, hardened, or ground? โผ
The appropriate route depends on load, speed, duty cycle, wear target, noise expectation, and drawing tolerance. Heat treatment can change dimensions, so surfaces requiring finishing after treatment should be identified on the drawing.
