Always 50+ tons of precision shafts in stock
Precision 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 precision 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.

Key properties of precision 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
