Industrial Drive Shafts and Flanged Shafts
We manufacture drive shafts, line shafts and flanged shafts that carry power from motors and gearboxes to the working machine – forged or from bar, CNC turned, splined and hardened to drawing.

From Gearbox to Machine
Drive shafts transmit torque from the motor or gearbox to the driven machine – a conveyor pulley, a mill, a pump, a roller or a winch drum. They often carry flanges or couplings at the ends, run in heavy bearings and must withstand shock loads and fatigue.
Nika Gears produces industrial drive shafts from forgings or bar stock, with flanges, splines, keyways and shrink-fit seats as drawn. Where the drawing calls for it, seats and splines are induction hardened and ground.

Drive Shaft Types
Forged Drive Shafts
Heavily loaded shafts start from forgings for better grain flow and fatigue strength, then are turned to size.
- Forged blanks
- UT testing on request
- Quench and temper
Flanged Shafts and Hubs
Shafts and hubs with integral or shrink-fitted flanges for bolted coupling to gearboxes and machines.
- Bolt circles drilled to drawing
- Faces machined square
- Shrink-fit or integral
Drive Hubs and Couplings
Turned drive hubs, coupling halves and adaptors that connect shafts to gears and machines.
- Bores with keyways or splines
- Flanged designs
- Series production

Questions About Drive Shafts
Do you make drive shafts from forgings?
Yes. For heavily loaded or shock-loaded shafts we recommend forged blanks, which can be ultrasonically tested on request.
Can you add flanges?
Yes, integral flanges turned from the forging or shrink-fitted flanges, with bolt circles drilled to drawing.
What length can you manufacture?
Up to 3,000 mm overall length and Ø800 mm diameter.
Do you make cardan or universal-joint shafts?
We manufacture the shafts, flanges and splined parts to drawing; complete cardan assemblies are not our product.
Industrial Drive Shafts: Material, Design and Manufacture
An industrial drive shaft connects the gearbox to the machine it drives. Unlike shafts inside a gearbox, drive shafts are often long, carry heavy overhung loads and see shock from the process – a crusher jaw closing, a conveyor starting under load, a winch catching a load. Fatigue strength and toughness matter as much as dimensional accuracy.
Forging or bar?
For moderate loads, rolled bar of 42CrMo4 or C45 is economical. For heavy, shock-loaded drive shafts, forged blanks are better: the forging process aligns the grain flow with the shaft contour and closes internal voids. Forged shafts can be ultrasonically tested before machining.
Connections at the ends
Drive shafts end in flanges, splines, keyways, tapers or shrink-fit seats. Each connection is machined to drawing: bolt circles positioned to the shaft axis, flange faces square, splines checked with gauges – see splined shafts.
Heat treatment
Most drive shafts are quenched and tempered for a strong, tough core. Bearing seats and splines are often induction hardened for wear resistance, then ground. Hardness is reported and material traced to EN 10204 3.1 certificates.
