Fine Pitch Micro Gears
Fine Pitch Micro Gears From Customer Drawings
Fine Pitch Micro Gears Manufacturer for M0.2-M1.0 Precision Transmission Parts
MH manufactures fine pitch micro gears according to customer drawings, 3D models, samples and technical specifications. For compact gearboxes, robot actuators, miniature motors and aerospace instruments, we review tooth geometry, burr risk, heat treatment deformation, runout, inspection method and batch consistency before confirming production feasibility.

Drawing-Based Evaluation for Very Small Tooth GeometryFine pitch gears are small, but the purchasing risk is not small. A gear with M0.2, M0.3 or M0.5 teeth may be sensitive to burrs, tool wear, heat treatment movement, tooth profile stability, bore concentricity and measurement access. MH reviews the whole drawing instead of quoting only by module and tooth count. M0.2-M1.0 / Fine pitch gears / Gear shafts / Small module spur gears / Drawing-based OEM |
What Are Fine Pitch Micro Gears?
Fine pitch micro gears are miniature gears with very small tooth spacing. In metric gear design, buyers often describe them by small module values. For MH projects, typical fine pitch examples include M0.2, M0.3, M0.5 and other small module gears within the M0.2-M1.0 range.
Compared with larger gears, fine pitch gears leave less room for machining variation. Tooth burrs, pitch error, runout, surface finish, heat treatment change and inspection method can directly affect noise, backlash, meshing smoothness and service life in compact transmission systems.

Before the Product List: Which Fine Pitch Gear Type Fits Your Project?
Use the product list below as examples of what MH has already produced or can evaluate. Your final part may need a different material, tooth count, hub, shaft, bore or surface treatment according to the assembly.
M0.2-M0.3 Ultra-Small GearsSuitable for compact mechanisms where space is limited. Process review focuses on burrs, tooth profile stability and measurement method. |
M0.4-M0.6 Fine Pitch GearsOften used when the design needs a balance between compact size and stronger tooth geometry for repeated motion. |
M0.7-M1.0 Precision GearsStill compact, but with more design flexibility for gear shafts, compact gear sets and higher-load small transmissions. |
Fine Pitch Micro Gear Drawing Case
A useful fine pitch case should show more than the gear shape. It should help buyers understand what MH reviews before production: gear parameters, datum, bore or shaft fit, surface finish, heat treatment and inspection items.

Example Review: Fine Pitch Gear With Small Tooth Features and Shaft/Bore RequirementsIn this type of project, the gear teeth cannot be evaluated separately from the complete part. MH reviews tooth parameters, runout, coaxiality, shaft or bore tolerance, burr removal, heat treatment requirement and inspection feasibility before confirming quotation and production route.

Manufacturing Challenges of Fine Pitch Micro Gears
Fine pitch gears are difficult because small process changes can affect actual gear performance. For purchasing engineers, the important question is not only whether the supplier can cut the teeth, but whether the supplier can control the part repeatedly.
| Ultra-Small Tooth Geometry | M0.2 and M0.3 teeth are sensitive to burrs, cutting edge condition, tool wear and tooth profile variation. |
|---|---|
| Heat Treatment Movement | Hardened fine pitch gears require early review of material, hardness target and deformation risk, especially for thin walls or integrated shafts. |
| Runout and Assembly Fit | For gear shafts and compact gearboxes, bore accuracy, coaxiality, runout and datum selection affect meshing, noise and service life. |
| Inspection Access | Small teeth and miniature parts may require a practical inspection plan before production, not only final visual checking. |
Manufacturing Route and Inspection Support
For fine pitch gear projects, MH selects a route according to gear size, material, heat treatment, shaft or hub structure and inspection basis. Specific equipment is used as engineering support, not as decoration on the page.
Gear Cutting and Micro MachiningRepresentative resources include Tokyo Wako H102C / 120A, Mikron 102-0.5, Ningjiang YG3612 / YKJ3610 and Baocheng T-YG3603 hobbing equipment, supported by small precision turning and machining resources such as Schaublin SBL series, Hardinge T42 / ST-216B and MAZAK INTEGREX i-250 when shaft features are integrated. |
Heat Treatment and InspectionVacuum quenching, vacuum tempering, vacuum annealing, plating, passivation and blasting can be evaluated according to the drawing. ZEISS CMM, ZEISS CONTURA, Mitutoyo height gauges and surface roughness testing support dimensional and surface review. |
Fine Pitch Micro Gear Applications
Application text should help a buyer judge whether MH understands the working environment of the gear, not just list industries.
Robot Actuators and Compact GearboxesFocus points include low backlash, smooth meshing, compact multi-stage layouts, batch consistency and stable fit with mating gears. |
Aerospace InstrumentsFine pitch gears for precision instruments may require traceable manufacturing, stable materials, controlled heat treatment and inspection documentation. |
Miniature Motors and Precision MechanismsNoise, vibration, tooth surface condition, bore fit and repeatable transmission behavior are usually more important than visual appearance alone. |
Information Required for Quotation
The more complete the quotation information is, the faster MH can evaluate feasibility, cost, inspection method and delivery risk.
| 2D drawing, 3D model or sample photos | Module, tooth count, pressure angle and mating gear information |
| Material, heat treatment, hardness and surface treatment | Bore, shaft, datum, runout, coaxiality and key tolerances |
| Prototype quantity, batch quantity and target delivery | Application background, inspection standard and documentation requirements |

Fine Pitch Micro Gear FAQ
This second-level FAQ is written for buyers who are checking whether a fine pitch gear drawing is suitable for manufacturing review.
What module range does MH review for fine pitch micro gears?
MH typically reviews fine pitch micro gear drawings from M0.2 to M1.0, including representative M0.2, M0.3 and M0.5 gear projects. Final manufacturability depends on gear structure, material, heat treatment and inspection requirements.
Is a fine pitch gear the same as a small module gear?
In many buying discussions, yes. Fine pitch gear is often used in English to describe gears with very small tooth spacing, while small module gear is a metric engineering expression based on module size.
Can MH manufacture M0.2 fine pitch gears?
MH can review M0.2 fine pitch gear drawings, but the quotation needs to check tooth geometry, burr tolerance, material, part size, quantity and inspection basis. Very small teeth require more careful process planning than ordinary gears.
Can MH make hardened fine pitch gears?
Yes, hardened gears can be evaluated when the material and hardness requirement are clear. For fine pitch gears, heat treatment deformation and post-treatment inspection should be considered before batch production.
What accuracy wording should be used for fine pitch gear drawings?
When a drawing requires gear accuracy, it is better to specify the standard clearly, such as ISO Grade 5 to 8 or the applicable JIS, DIN or AGMA reference. MH reviews the inspection basis together with the drawing.
Can MH quote if the buyer only has a sample?
A sample or photo can start a technical discussion, but a formal production quotation usually needs confirmed dimensions, material, tolerance, gear parameters and acceptance criteria.
Which applications commonly use fine pitch micro gears?
Fine pitch gears are used in robot actuators, humanoid robot hands, miniature gearboxes, aerospace instruments, medical device mechanisms, precision motors and compact automation systems.
What should I send for a fast fine pitch gear review?
Please send a 2D drawing or 3D model, module, tooth count, material, heat treatment, surface treatment, tolerance, quantity, application background and any mating gear or assembly information.
Need Fine Pitch Micro Gears Made From Your Drawing?
Send your drawing, 3D model, sample photo or technical requirement. MH will review the gear geometry, material, heat treatment, inspection basis and manufacturability before quotation.
