Splined Shaft Profiles
Splined sections in quenched and carbon steels for agricultural power transmissions
What Splined Shaft Profiles Is and Who It Is For
Special profiles for splined shafts are used in universal joints and agricultural power transmissions, made in quenched steels and carbon steels. The spline form is produced in the profile itself, so the shaft arrives with the drive geometry already on it instead of being hobbed or broached from round bar.
Key Benefits
- Drive geometry formed in the profile rather than cut afterwards
- Quenched grades available where the joint sees shock loading
- Long lengths cut down to several shafts from one bar
- Consistent spline form along the whole length of the drawn bar
| Typical materials | quenched steels and carbon steels |
|---|---|
| Cross section | to customer drawing |
| Cold drawn size tolerance | < 0.05 mm |
| Cold drawn straightness | < 0.1 mm/m |
| Length | up to 6 m or cut to fixed length |
Who It Is For
- Agricultural driveline manufacturers
- Universal joint and PTO shaft makers
- Repair and spare part suppliers for implement drives
Problems It Solves
- Broaching or hobbing splines from round bar is slow and expensive
- Cut splines vary between batches and bind in the mating tube
- Welded drive adapters fail under shock loads in field service
Technical Features
- Spline form drawn into the section
- Quenched steels and carbon steels
- Male and female sections to the same drawing set
- Cut to driveline length

How It Compares
A drawn splined profile removes the spline cutting operation completely, while a machined spline stays the better route for one-off shafts or for splines that must be cut onto an existing forging.
Use Guide
- Supply both mating sections on one drawing so the fit is defined
- State the torque and whether the joint sees shock loads
- Confirm the cut length and any end preparation
