Manufacturing of:

– piston rods
– cylinder tubes
– complete cylinders
– bushings and rams
– and many more.

On our precision lathes we manufacture turning workpieces of any type. You will always get a top product as result, whether we manufacture according to special customer wishes – for example while repairing or overhauling hydraulic cylinders – or produce a complete new cylinder.

We carry a very large piston bar deposit in different qualities: 20 MNV6 for normal duty and 42 CroMo 4 V for heavy duty. Hence we are able to manufacture from 12-70 mm to 6000 mm of length and 75-140 mm to 4000 mm of length in shortest time.

CNC-Saw
For single copies and large-scale production up to (d) 260 mm; length measurement and quantity is unlimited.

Phases of manufacturing


First step:
Raw material sawed to measure


Second step:
Filing of the shaft


Third step:
Pre-turned shaft


Forth step:
Completed shaft                

Piston bars

We have piston bars in the qualities 20 MnV6 and 42 CrMo4V in stock. This makes manufacturing of piston bars on a short notice possible, for use in e.g. building machines, fork lifts, industrial cylinder, mining/tunnel construction, municipal cylinder etc.
The application of the 1.4057 ranges for example from shipmotors, dairy to papermills.
