Hardened ground shafts
Always 50+ tons of hardened shafts in stock
Hardened ground shafts are steel shafts the outer layer of which has been induction hardened. They are primarily known for their linear application, and are also called linear shafts or precision shafts. The hardened exterior and the “soft” core mean the shafts are highly durable and brittleness is prevented.

Operations of hardened ground shafts
For cutting the shaft to length and adding all required features we have our own linear machining center. Common operations include axial and radial holes, these are usually provided with thread. In addition most other operations are also possible, such as holes, flat sides and keyways. We are happy to advise you on the required operations.
Properties of hardened ground shafts
Key properties of hardened ground shafts are:
- High-precision tolerances on diameter
- High-precision tolerance on roundness
- High-precision tolerance on straightness
- High-precision tolerance on parallelism
- Low surface roughness
- High wear resistance due to hard exterior
Applications of hardened ground shafts
Common application of hardened ground shafts are:
- Linear applications
- General mechanical engineering
- Hinge pins for heavy loads
- Piston rods for heavy-duty applications
- Corner profiles for bending machines
- Basic material for ball screws
- Drive shafts for heavy-duty applications
Product finder shafts
Find the right shaft for your applications with the online product finder. Enter the values you need, choose a type of shaft and the product finder will calculate the maximum deflection of the shaft. This way you immediately know which axles are most suitable for your application.
