ø 1000 - 8000 mm
The structure is triple row cylindrical roller type with external gear.
In order to have the best and stable mechanical property, the 3 rings are forged and each ring is unitary.
In order to guarantee the hardened depth on the raceway, a test was made before the induction hardening.
