Gears for Chemical and Process Plants
Agitators, reactors, dryers, kilns and pumps run continuously in demanding atmospheres. We manufacture gears, bevel and planetary sets and shafts for chemical and process plant drives.

Continuous Process, No Unplanned Stops
Chemical and process plants run continuous or long batch processes where an unplanned stop can spoil a batch or shut down a unit. Agitator and reactor drives, rotary dryers and kilns, pumps and compressors all depend on gearboxes that run reliably between planned shutdowns.
Nika Gears manufactures the gears and shafts for these drives – bevel and planetary stages for agitators, large girth-drive pinions for dryers and kilns, and precision gears for pumps and compressors – with full traceability.

Chemical Industry Gear Questions
Can you supply agitator gearbox gears?
Yes – bevel, helical and planetary gears and splined output shafts, as OEM parts or spares.
Do you make pinions for rotary dryers and kilns?
Yes, forged pinion shafts and spur gears up to Ø1,800 mm and module 30.
Can you supply stainless steel gears?
On request, for parts exposed to process media. We advise on the reduced load capacity.
Gears for Agitators, Dryers and Process Drives
Gear drives in chemical and process plants are planned for reliability. Maintenance is scheduled around shutdowns, so every gear must last until the next one. That calls for proven materials, careful heat treatment and complete documentation.
Agitator drives
Reactors and tanks are stirred by agitators driven through bevel-helical or planetary gearboxes. The bevel stage turns the drive vertically, and the output shaft – often splined – carries the agitator. These drives run slowly with high torque and must handle the bending loads from the agitator.
Rotary equipment
Rotary dryers, kilns and granulation drums are driven through a pinion meshing with a large girth gear on the drum. The pinion wears first and is the usual spare part; we manufacture forged, induction-hardened pinion shafts to drawing.
Pumps and compressors
Pumps, compressors and blowers often use speed-increasing gearboxes with precision helical gears, case hardened and ground for quiet running at high speed.
