Opis
Round Gear Rack
Round rack components for compact linear motion mechanisms, produced to drawing with the tooth system and end machining required by the assembly.
Where this component fits
Round rack components for compact linear mechanisms where the rack is carried on a cylindrical body rather than a rectangular section.
Compact actuators, adjustment mechanisms, special machinery and custom motion devices can use round rack forms.
Technical specifications
The values below are the current catalogue and drawing-based scope already associated with this product family. Where a value is described as project-specific or “confirm drawing,” the released drawing remains the final technical reference.
| Section | Round / cylindrical rack body |
|---|---|
| Tooth system | Straight or drawing-specific |
| Ends | Thread, step, flat or other secondary machining by drawing |
| Material | Steel/stainless or specified alternative |
| Quantity | Prototype and production batches reviewed case by case |
Selection should follow the mating component and the real duty
A round rack is normally drawing-driven because end features, support/bearing surfaces and the relation between the tooth line and shaft diameter affect the assembly.
If a requested parameter is not yet fixed, provide the functional target and allow it to remain an open selection item. That is safer than locking the project to an assumed value that has not been checked against the mating component or machine.
Details that change the quotation
These fields help separate a standardizable configuration from a part that needs drawing-specific machining or inspection.
| Tooth system | Confirm module/DP/CP, pressure angle, tooth form and helix details where relevant. |
|---|---|
| Machine duty | For driven axes provide travel, load, speed, acceleration, duty and positioning target. |
| Material/treatment | Use the drawing requirement or state the performance need if a material route is still open. |
| Mounting geometry | Length, cross-section, hole pattern, end conditions and datum surfaces. |
| Finish/accuracy | State the drawing tolerance or functional accuracy need; do not default to the highest grade. |
| Quantity | Prototype, first production batch and repeat demand if known. |
Process route follows the ordered specification
Rack manufacturing can combine blank preparation, datum machining, tooth generation, heat treatment where specified, tooth finishing where required, secondary hole/end machining and final inspection. The sequence depends on material, hardness, accuracy and distortion risk.
Material substitutions, heat-treatment changes and tolerance relaxations should be approved before production. For repeat orders, the approved drawing revision and any agreed inspection scope should remain attached to the order.
Fit, mounting and mating-part considerations
Support and anti-rotation features should be considered together with the rack teeth. A cylindrical body alone does not define how the part will be constrained in the mechanism.
For replacement work, send the existing part or assembly information as identification support, but confirm the production dimensions before release. Visual similarity is not a substitute for the tooth and interface data.
Inspection should follow the functional datums
Inspection should include diameter, straightness, end features, tooth geometry and the relationship between teeth and the cylindrical datum.
If dimensional reports, material certificates or heat-treatment records are required with the order, identify them in the RFQ so they are included in the quality plan rather than requested after production is complete.
Products commonly reviewed together
Related components are shown as practical design companions, not as claims that every item is automatically compatible. Match the actual drawing and mating tooth data before ordering.
What to send for a useful quotation
Attach the latest drawing and state quantity, material, treatment, tooth data and critical inspection requirements. For rack-driven motion, add the axis duty and the mating pinion/gearbox details where available. STEP or DWG files help when secondary machining and interfaces are complex.
