Gear Racks, Pinions & Custom Precision Gears

Use the catalogue in two ways. If a drawing already defines the component, start with the closest product family and send the controlled dimensions. If the drive is still being selected, begin with the machine duty and let module, tooth form, finish and pinion geometry follow from the application.

Product families

Three product groups cover most enquiries.

The catalogue is intentionally organized by buyer task rather than by a long list of proprietary model codes. Gear racks cover linear motion. Pinions and pinion shafts complete the rack drive. Custom gears support gearboxes, indexing mechanisms and special machinery where the drawing owns the geometry.

Gear racks

Choose the tooth form and finishing route around the axis.

Straight and helical racks are available in drawing-based configurations, including milled, induction-hardened and ground-tooth routes where the specification requires them. Length, hole pattern, end machining and mounting datums are treated as part of the component, not as afterthoughts.

For long axes, quote the rack together with the intended pinion or at least provide the pinion tooth data. Joined sections, pitch transition, backlash and the mounting base affect how a rack performs after installation.

Pinions and pinion shafts for rack drives
Mating components

Pinion geometry has to match the rack and the gearbox interface.

A rack is only half of the mesh. Bore, keyway, spline, shaft or flange geometry on the pinion should fit the real drive arrangement while module, pressure angle, helix angle and hand remain compatible with the rack.

Where positioning or high reversal duty matters, include the gearbox output, bearing arrangement and desired backlash in the enquiry. That information helps avoid a mechanically correct pinion that is awkward to integrate.

カスタムギア

Use the drawing as the technical contract.

Custom gears are quoted from tooth data, bores and hubs, material and heat treatment, inspection requirements and quantity. Spur, helical, bevel and internal gears often need different manufacturing routes, so one generic “gear tolerance” statement is not enough.

When a mating gear controls contact or backlash, send both gears together. For replacement work, include the old part drawing, measurements or photos only as identification support; final manufacturing dimensions should be confirmed before production.

What to decide before choosing a product page

These are the variables that usually change the manufacturing route, price and suitability. Unknown values can stay open, but they should be identified as open rather than guessed.

Tooth system Metric module, diametral pitch or circular pitch; pressure angle and helix details where relevant.
Motion or duty Travel, speed, acceleration, load, reversal frequency and required positioning quality for rack-driven axes.
材料 Drawing grade or a performance requirement that allows an equivalent material route to be proposed.
熱処理 Through hardening, induction hardening, carburizing or other drawing-controlled treatment when required.
Finish and accuracy Milled, ground or another specified finishing route; include the applicable gear-quality or dimensional tolerances.
Machining interfaces Holes, countersinks, ends, bores, keyways, splines, shoulders, shafts and the datum scheme used for inspection.
Quantity Prototype quantity, first production batch and expected annual demand when available.

Browse all current product entries

Each product page includes a responsive specification table, configuration guidance, integration notes and the RFQ information needed to quote the part. Values that depend on the drawing are stated as project-specific instead of being filled with assumed data.

Custom machined gear rack mounting holes and tooth section
Custom-to-drawing work

Standard teeth can still sit on a highly customized component.

Many OEM racks use a familiar tooth system but require non-standard cross-sections, mounting-hole locations, end preparation or inspection datums. Those details should remain on the drawing and stay visible during quotation, manufacturing and inspection.

If the design is still open, send the machine envelope and the functional requirement. If the design is frozen, send the latest revision of the drawing and clearly identify which dimensions or notes are critical.

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。
