Girth Gears
Harcliff’s operations span across the globe, making us a leading precision gear manufacturer with extensive knowledge in gear manufacturing techniques.
Girth Gears
Our girth gears are manufactured from alloy steel castings, forged, fabricated and ductile iron options with a capacity of up to 150 ton or Ø14m per gear.
In addition to manufacturing new products, we also modify and improve existing gear designs through the utilisation of advanced design and gear calculation software.
Specifications
Our state-of-the-art gear grinding technology enables us to supply gears of the highest quality.
Accuracy classes achievable:
- AGMA Q12 and higher
- Super-fine surface finish (<0,8Ra)
Manufacturing
- Steel castings with a capacity of up to 150 tons per gear set
