Gear Rack & Pinion Components for Industrial Motion
A rack-driven axis is selected from the machine duty, not from module alone. Travel, moved mass, process force, speed, acceleration, positioning, duty cycle and mounting geometry determine whether the application needs a simple milled rack or a more controlled rack-and-pinion set.
Start from the motion problem, then choose the component.
Long-travel CNC, robot seventh axes, cutting gantries, material-handling systems and heavy positioning equipment can all use rack drives, but they load the teeth and mounting structure in very different ways.
The application pages below describe the variables that matter before module, tooth form and finish are finalized. They are intended to help a buyer prepare an RFQ that contains enough information for a meaningful technical review.
Choose the machine context closest to your project
Each application page links back to the most relevant rack, pinion and custom-machining options and explains what should be checked during integration.
The same rack behaves differently when the duty changes
Use the following data as a common application brief. It is especially useful when the machine is still in the selection stage and no final rack drawing exists yet.
| Travel and axis layout | Total stroke, horizontal/vertical orientation, number of rack sections and available mounting length. |
|---|---|
| Moved load | Carriage, fixture and payload mass plus external process forces. |
| Motion profile | Maximum speed, acceleration/deceleration, reversal frequency and daily duty. |
| Positioning | Required repeatability, accuracy, allowable backlash and motion smoothness. |
| Environment | Dust, chips, coolant, washdown, temperature and access for lubrication. |
| Drive interface | Motor/gearbox type, output shaft/flange, pinion location and space for bearings or supports. |
| Service expectations | Maintenance access, lubrication method, expected operating hours and replacement strategy. |
Rack quality cannot compensate for a poor mounting base.
The mounting surface, rack-to-rack transition, pinion alignment and lubrication path all influence the final motion quality. On long axes, the joint between rack sections deserves the same attention as the tooth form itself.
For retrofit projects, also record the available envelope and the existing pinion/gearbox interface. A part that is dimensionally close but incompatible with the drive arrangement can create more work than a correctly scoped custom component.

A useful quotation starts with the geometry and the operating context. Send the drawing, quantity and controlled requirements; for rack-driven axes, add travel, speed, acceleration, load and the mating pinion or gearbox information when available.
注文方法： 最小注文数量（MOQ）は、製品の種類と注文金額によって柔軟に対応可能です。新規顧客向けのサンプルは1～5個が適切です。複数モデルを組み合わせた注文は、合計金額が1,500米ドル以上であれば対応可能ですが、1～2個の場合は単価が高くなります。
時期と条件： 標準部品の納期は通常10～25営業日、特注部品は20～45営業日、プロジェクト機器は45～120営業日です。EXW、FOB、CIF、DAPは一般的に利用可能ですが、FCA、CFR、CPT、CIP、DDPについては個別にご相談ください。
