Zerol Bevel Gear Machining Service
milling
Milling delivers flexible, CNC-controlled cutting for prototypes and small batches.Ideal for thin-plate parts and non-standard bevel gears where tooling needs to stay agile.
forging
Forging forms dense blanks with improved grain flow for high-load bevel gear applications.
Best for robust gear blanks that require strength before precision machining.
Powder metallurgy
Powder Metallurgy makes near-net-shape gears with consistent repeatability at scale.
Great for small-module or complex geometries, cutting material waste and machining time.
Quality Control
Prior to every shipment, we conduct the following tests and provide complete quality reports for these gears.:
1. Bubble drawing
2. Dimension measurement report
3. Material certification report
4. Heat treatment testing report
5. Accuracy measurement report

Packaging
Step 1 – Anti-rust: We wrap each gear with VCI anti-corrosion paper / bag to protect it from rust during shipping.
Step 2 – Inner protection: The wrapped parts are placed properly to avoid scratches and impact.
Step 3 – Carton packing: Then we pack them into strong export cartons (logo printing is available).
Step 4 – Crate & pallet: Cartons are loaded into a reinforced plywood crate with partitions, and fixed on a pallet.
Step 5 – Secure & label: The crate is sealed, strapped, and labeled, ready for sea/air shipment.
We can also provide custom printed color boxes and logo customization (carton, color box, crate marking, labels).
Note: Please ensure the logo/design is authorized by you; if it involves any third-party brand, we will need written authorization to avoid IP risks.
FAQ
Where are zerol bevel gears typically used in agricultural conveyors?
Zerol bevel gears are used in agricultural conveyor and grain-handling drives where a compact right-angle transfer is needed and stable meshing is important.
Can you make a replacement gear based on a worn part?
Yes. For replacement work, a sample gear plus photos of the housing and shaft interface helps. If possible, include the mating gear to confirm the mesh relationship.
What material and heat treatment are common for farm-duty bevel gears?
Most agricultural duty gears use alloy steel with heat treatment selected around torque, shock loads, and expected life. If you have hardness targets, share them; otherwise we can suggest practical options.
How do you handle dusty or abrasive operating conditions?
The gear itself is only part of it. We usually ask about sealing, lubrication method, and contamination level. With that information, we can recommend surface protection and a realistic inspection focus.
What are the key parameters to include in an RFQ?
Ratio, shaft angle, module/DP, tooth count, face width, bore details, mounting distance/center distance, backlash target, and quantity. If space is tight, include envelope limits.
Can you provide inspection evidence for incoming QC at our warehouse?
Yes. We can provide a gear inspection report aligned to what your QC checks (dimensions, runout, tooth measurement). Tell us your critical characteristics and sampling plan.
