100% dimensional inspection
After heat treatment, the dedicated visicontrol system checks diameter, length and edge rounding. Sampling accompanies subsequent machining.

Precision that moves.
Piston pins, crank pins and precision turned parts from wire and bar. From one part to production runs in the millions.
Our manufacturing capabilities
What we manufacture for you
Our core product
Piston pins and crank pins
Our core range: Ø 8–20 mm. We also manufacture other designs up to Ø 60 mm to meet your requirements.

15million parts / year
Piston pins and crank pins in our core range of Ø 8–20 mm
Experience in series production
From one part to millions.
Within this range, we manufacture approximately 15 million piston pins and crank pins combined each year. We complement this production experience with new capabilities in wire turning. Single parts and samples can also undergo the complete manufacturing process chain they require.
Your component. The right process.
We match material, machining and inspection to your drawing. Precision round wire can eliminate an additional grinding step for suitable parts.
Explore productsThe manufacturing chain
From material to finished component.
We align material, machining and inspection with your drawing. In-house heat treatment and precision finishing bring the manufacturing stages together through direct coordination.
Wire or bar
The right starting stock for your component’s material, geometry and production volume.
Turning
ESCOmatic, CNC sliding-head turning or multi-spindle machining: the process follows the task.
Heat treatment
When required: quench and temper, carbonitriding or case hardening in our own heat treatment facility.
Finishing
When required: centreless grinding or lap grinding to achieve the specified dimensions and surface.
Inspect and pack
Measuring equipment from Mahr, Mitutoyo and KEYENCE. Piston pins and crank pins are individually inspected and packed, regardless of diameter.
Measurable precision
One micrometre. And below.
- Surface roughness
- Rz < 0.6 µm
- Roundness
- < 1 µm
- Total diameter tolerance width
- 3 µm
Jointly achievable for suitable parts up to Ø 20 mm in validated series production. Subject to material and geometry; agreed using your drawing. Above Ø 20 up to Ø 60 mm: a total outside-diameter tolerance width of 4 µm.
Quality and inspection in detailMeasure. Inspect. Pack.
Precision through the final step.
Measuring technology from Mahr, Mitutoyo and KEYENCE supports our production. We individually inspect and pack every piston pin and crank pin at the end, regardless of diameter.

What would you like us to manufacture?
Your drawing and required quantity are enough to get started. For clearly specified standard piston pins, dimensions, standard design and quantity are sufficient for the initial enquiry.
We clarify outstanding requirements before preparing a quotation.
