With more than 1000 girth gears sold over the world CITICIC Gear is a leading supplier in the cement and mineral industry. And as member of AGMA (American Gear Manufacturers Association), we do actively take part in defining the standard for gear rating calculations and service factors.
We provide girth gears in three different designs
- Fabricated steel
- forged ring
- rolled plate
- Cast steel
- Ductile (Nodular) cast iron
Fabricated gears became more common in the past and are constructed with forged steel gear rim materials and electro welded body structure. The rings are manufactured from a whole block of high resistance alloy steel. After the rough machining of the ring, we carry out hardening and tempering heat treatment in order to improve the mechanical characteristic and therefore its relevant performance.
Avantages of fabricated girth gears
- The forged material structure excludes the risk of inclusions
- Structure defects like gas holes, micro shrinkage, pin holes, hot tears, sand and slag inclusions are avoided
- Hence, repair welding of the body structure and e.g. grinding of toothed areas is not required.
- The fabricated manufacturing procedure excludes the need for patterns and risers
- Rim material has higher hardness and higher strength than the material used for the underlying structure (i.e. web, gussets)
These features will reduce the lead time and costs. Fabricated manufacturing ensures a fast delivery.
This is especially beneficial in an emergency situation, where the existing gear rim is suffering from damage

Pinions
CITICIC Gear invested in significant resources and achieved many innovations with pinions. The right combination of material, hardness and finishing between pinion and gear is crucial for a long lifetime of the installed equipment. We design and manufacture pinions to match every customers need, no matter how unique the situation might be.
Pinion design
- bored
- solid on shaft / integral
- self aligned
- spur, helical or double helical
Materialization
- forged alloyed steel
- through hardened, case hardened or quenched and tempered
- Spur, helical or double helical
- carburized
- induction
- nitrided
Characteristics
- gear cutting with hobs
- the gear quality is checked by profile tester
- tooth flank modification
- profile correction
- lead correction (straight/barrel)
- designs /ratios according to ISO-DIN-A.G.M.A.
- FEM/FEA simulation software
Applications
Our pinions are applied in the cement and minerals industries:
- Ball - mills
- ROD - mills
- Semi Autogeneous Grind (SAG)
- Rotary kilns/coolers/dryers
Advantages
- One Source
- Original Equipment Manufacture (OEM) Technical Drawings
- Gearing technical expertise for kilns and grinding mills
- State of the art manufacturing facilities and quality
- Global sales and service support
