Splined Shafts to DIN 5480, DIN 5482 and ANSI
We manufacture splined shafts, splined pinion shafts and matching splined hubs – hobbed or shaped, hardened and checked with spline gauges – for gearboxes, PTO drives, couplings and machine drives.

Torque Transmission Without Keys
A spline connects a shaft and a hub through many teeth instead of a single key. Load is spread over the whole circumference, so splined connections carry more torque, centre the hub better and allow axial sliding where needed. Involute splines are the standard in gearboxes, power take-offs, couplings and vehicle drivelines.
Nika Gears cuts external splines by hobbing – including long shafts on a horizontal hobbing machine – and internal splines by shaping. Every spline is checked against the standard and fit class on your drawing.

Questions About Splined Shafts
Which spline standards do you work to?
DIN 5480, DIN 5482, ANSI B92.1 and ISO 4156 involute splines, as well as straight-sided splines to drawing.
How do you check spline fit?
With go/no-go spline gauges and over-pin measurement against the fit class on the drawing.
Can you make the matching hub?
Yes. Internal splines are shaped on our gear shapers – see internal gears.
How long can a splined shaft be?
Up to 3,000 mm overall, with splines hobbed up to 2,000 mm length.
Splined Shafts: Standards, Fits and Manufacturing
Splines are the backbone of torque transmission in modern machinery. Compared with a keyed connection, an involute spline spreads the load over many teeth, centres the hub accurately and can allow axial movement – which is why gearboxes, PTO drives, couplings and hydraulic units rely on them.
Spline standards
In Europe, DIN 5480 is the most common involute spline standard; DIN 5482 is still found on older and agricultural equipment; ANSI B92.1 and ISO 4156 appear on American and international drawings. Each defines module, pressure angle, number of teeth and fit classes. We manufacture to the standard and fit class stated on your drawing.
Manufacturing
External splines are hobbed. Long shafts are hobbed on a horizontal WMW Heckert machine. Internal splines in hubs and gears are shaped. Bearing seats are ground after hardening so the spline runs true to the bearings.
Heat treatment
Induction hardening is the most common treatment for splined shafts: it hardens the spline teeth and seats while keeping a tough core. Case hardening and nitriding are used where the drawing requires them. Hardness and case depth are reported with the parts.
Inspection
Spline fit is checked with go/no-go gauges and over-pin measurement, and runout is measured relative to the bearing seats. Material is traced to EN 10204 3.1 certificates.
