描述
Direct answer
Pinion tooth geometry must match the rack; bore/shaft interface is project-specific. Final dimensions, material, treatment, finish and inspection scope are confirmed for the ordered configuration.
Selection variables
音调系统
Module, DP or CP must match the mating pinion.
压力角
Confirm from the machine drawing or existing tooth system.
Rack geometry
Body section, length, mounting holes and end features.
Accuracy
State drawing tolerance or target gear quality class.
Material & treatment
Define grade, treatment and hardness when they are design requirements.
Duty
Travel, speed, acceleration, load/force, cycle and environment.
Technical specification table
| 规格 | 项目/订购要求 |
|---|---|
| Product family | Matching pinion |
| Tooth pitch | Project-specific module / DP / CP; verify from drawing/RFQ. |
| 压力角 | Confirm for ordered configuration. |
| Helix data | Confirm where applicable. |
| Rack length / section | Drawing- and project-specific. |
| Rack body / holes | Drawing-defined dimensions and mounting pattern. |
| 材料 | Specified by drawing and duty; final grade confirmed with quotation. |
| Heat treatment / hardness | Specified by required wear/load behavior and drawing. |
| Tooth finish | Cut / hardened / ground as ordered and technically applicable. |
| Quality / tolerance | Target DIN/ISO/AGMA or drawing tolerance to be stated by buyer. |
| Pinion interface | Matching tooth system; pinion bore/shaft/hub is project-specific. |
| Quantity | Required for quotation and process planning. |
Rack and pinion must be treated as one tooth system
A rack cannot be selected independently from the mating pinion. Confirm the same pitch system and pressure angle, then check helix geometry where applicable. Replacement work should also verify wear and any machine-side geometry that could change the installed mesh.
Long travel needs section alignment
When the axis uses several rack sections, specify the segment length, joint relationship and mounting datum. Installation error can overwhelm the nominal rack accuracy if the machine surface and joints are not controlled.
Material, heat treatment and finish
The process route is selected from the drawing and the performance target. Do not assume a material or hardness from another supplier’s catalogue is automatically the right specification for your machine.
Material grade
State the required alloy/steel grade or allow project-specific selection review.
热处理
Define the target hardening/treatment condition if required.
Tooth finish
Cut, hardened or ground tooth finish according to the requested configuration.
Protection
Specify corrosion protection only when the environment requires it.

RFQ checklist
Attach the rack drawing and send the mating pinion information, quantity and machine duty. For a replacement, include photographs and any markings as secondary identification aids.
常见问题解答
Can this product be made to a drawing?
Yes, drawing-based projects can be reviewed. Final feasibility depends on dimensions, tooth geometry, process, quantity and inspection requirements.
Can you guarantee a quality class from this page?
No. The exact class/tolerance is confirmed for the ordered configuration and should appear on the drawing or quotation.
Can the mating pinion be quoted together?
Yes. Quoting both parts helps keep the tooth system and interface controlled.
Send the rack and pinion data as one RFQ.
请提供齿条类型、节距系统、压力角、所需长度、配套小齿轮数据、目标精度或公差、工作工况和数量。图纸是消除歧义最快捷的方式。
