Have you ever wasted money on ready-made ring gears that cannot fit your equipment perfectly?
Lots of equipment owners and global purchasing managers run into the same headache: standard off-the-shelf ring gears never match old machine installation holes, wrong tooth modulus leads to abnormal vibration and loud noise after installation. When you search for custom machined ring gear online, you may also worry about inaccurate processing, poor heat treatment and long production cycle delaying your maintenance or new project schedule.
Custom machined ring gear is designed exactly around your equipment parameters to avoid all these unnecessary losses.

Many buyers fail in custom ring gear procurement mainly for four reasons:
Suppliers make gears only by rough data without professional dimension checking, finished products can’t be mounted directly, resulting in high return and ocean freight cost.
Inferior raw material and irregular quenching craft cause rapid tooth pitting, crack and breakage within several months under heavy-load mining and cement working conditions.
Most small workshops cannot provide complete material test report and inspection certificate, goods get stuck at customs when importing to EU, USA or Russia.
Unstable factory schedule leads to delayed delivery, your mine or factory has to stop production waiting for spare girth gear.
These hidden costs are far higher than the gear itself. That’s why reliable custom machined ring gear manufacturers become the top choice for global buyers.


First, we accept customization based on your CAD drawing, physical old sample or equipment model number. Our mechanical engineers verify all parameters including modulus, tooth precision, outer diameter and mounting hole size before formal production to eliminate dimension error.
Second, all customized ring gears adopt qualified forged steel with standardized heat treatment. Every finished piece goes through magnetic particle inspection and ultrasonic test; full set of material certificate, hardness test document will be provided together with shipment for smooth customs clearance.
Third, flexible production arrangement shortens lead time for urgent maintenance orders. For regular custom ring gear, we keep reasonable production cycle while controlling product quality. All our custom machined ring gears come with official written 12-month warranty against non-human damage.
