Linear Guide Rail Profiles
Rail and carriage sections in induction hardening and case hardening steels
What Linear Guide Rail Profiles Is and Who It Is For
Profiles for linear guides are used to produce both the rails and the carriages of the guide. They are generally produced in carbon steels, in induction hardening alloy steels and in case hardening steels, because the running surfaces have to take a hardened track while the body of the section stays tough.
Key Benefits
- Section geometry drawn to the raceway you grind, so less stock is removed at the grinder
- Grade choice matched to whether the track is induction or case hardened
- Straightness held tight enough that long rails do not need pre-straightening
- Prismatic, trapezoidal and complex geometry guides all made from the same programme
| Typical grades | carbon steels, induction hardening alloy steels, case hardening steels, 100Cr6, Cf53 |
|---|---|
| Cold drawn size tolerance | < 0.05 mm |
| Cold drawn straightness | < 0.1 mm/m |
| Cross section | to customer drawing |
Who It Is For
- Linear motion component makers
- Machine builders producing their own guideways
- Sliding system suppliers in steel for bearings
Problems It Solves
- Grinding a raceway out of plain bar removes far more material than it should
- Mixed grades across a rail batch give inconsistent hardening depth
- Long rails supplied bent add a straightening operation before grinding
Technical Features
- Induction hardening alloy steels and case hardening steels
- Bearing steel grades such as 100Cr6 and case hardening grades such as Cf53
- Prismatic, trapezoidal and complex geometry sections
- Cold drawn tolerances where the raceway geometry demands it

How It Compares
Compared with buying a standard guide rail, a drawn profile lets you own the raceway geometry and the hardening route, which matters when the carriage is your own design.
Use Guide
- Give the raceway geometry and the grinding allowance separately
- State the hardening method planned so the grade suits it
- Confirm the maximum rail length your grinder can take
