Parts for
six industries.
Mining
Continuous heavy duty
Ball mill girth gears · drive gears · large shafts
Ball mills run non-stop; tooth hardness and journal wear set the maintenance interval.
Metallurgy & steel
Impact loads
Mill gear shafts · couplings · castings and forgings
Impact loads: forging inspection first, tooth hardening after — both in-house.
Petroleum
Demanding conditions
Drilling and production shafts · hydraulic cylinders · non-standard parts
Material, sealing surfaces and thread accuracy follow the customer standard, not ours.
Chemicals
Corrosive, pressurized
Agitator shafts · pump castings · flanges and seal seats
Process medium and pressure class decide the material first; sealing faces and bolt holes are machined from one datum.
Shipbuilding
Large weldments
Propulsion gears · steering gear shafts · deck machinery parts
Large set-ups and weld distortion are the hard part: critical bores are checked from the machined datum.
Wind power
Cyclic loads
Yaw ring gears · main shafts · bearing housings
Cyclic loads: forging inspection and tooth hardness set the acceptance standard together.
For unusual parts we can measure your sample or reproduce it: material and working conditions first, then the process. Kiln and mill drives for cement plants, and bull gears for sugar mills, take the same route.
