Mating geometry
Matching module alone is not a complete specification; pressure angle and, for helical pairs, the helix relationship also matter.

Rack Mounting Machining
- Base rack specification
- Hole positions and sizes
- End features
- Drawing revision and quantity
Photographs can support identification but do not replace dimensions for machining review.
Bevel Gears
- Gear model or tooth drawing
- Tooth count and mating reference
- Shaft-angle requirement
- Bore and hub dimensions
A tooth-count ratio does not define the complete mating geometry. Use the approved drawing or exact model references.
Worm & Wheel Sets
- Worm and wheel references
- Specified ratio and tooth geometry
- Hand and shaft arrangement
- Material and interface drawings
The same ratio does not establish interchangeable mating parts. Supply the paired model references or complete drawings.
Internal Gears
- Tooth specification and count
- Mating pinion reference
- Outside and mounting dimensions
- Material and treatment requirements
The external ring diameter does not define the internal tooth specification. Provide the full model or dimensioned drawing.

PRODUCT FORMS
A clear view of the available forms.
Rack-and-pinion supply is organised around a mating pair and its installation. Tooth geometry, mounting references and drive interfaces remain connected throughout the quotation.
| Product form | Construction | Selection focus | Connected components |
|---|---|---|---|
| Spur rack and pinion | Straight teeth along the rack and mating gear | Module, pressure angle and mating tooth specification | Pinion shaft, support bearings and mounting parts |
| Helical rack and pinion | Angled teeth with a defined mating helix combination | Helix direction, tooth reference system and axial force | Reducer interface and an appropriate shaft support |
| Joined rack sections | Multiple rack lengths arranged along one travel axis | End preparation, joint alignment and mounting-hole layout | Long-travel guides and locating elements |
| Bore-finished pinion | Gear hub finished for a specified shaft connection | Bore fit, keyway or clamping arrangement | Output shaft, retaining parts and custom machining |
INTERFACE & SELECTION
The details that connect the assembly.
Long-axis installation
Reference surfaces, hole positions and rack joints are considered as one installation to avoid isolated section decisions.
Drive-side connection
Pinion overhang and shaft engagement are reviewed together with the reducer output and its permissible loading.
INTEGRATED SUPPLY
Connected parts in one component list.
Drive output
The output interface connects reducer selection to the pinion bore and mounting position.
ReducersTravel support
Guide rails define the travel direction used by the rack installation and pinion engagement.
Linear GuidesAlignment and fixing
Locating and fastening components support section alignment and repeatable installation.
Precision Locating FastenersRFQ information
A complete model is enough to begin. Partial information is welcome too.
A model, photo, drawing or BOM can start the discussion; brand, quantity and critical interfaces can be clarified by item.
