Piston Gudgeon Pin

Manufacturing Scope

Piston Gudgeon Pin is a Automotive Precision Parts family precision-turned on a Goodway SW-20, covering 8 variants — diameters ⌀4–16 mm, lengths 16–52 mm, standard material Steel (also steel, stainless, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request an instant quote with the code you need.

The family is machined from ⌀16 mm bar stock; its longest variant is OTOA-GPN-16 at 52 mm. Besides turning, the family requires axial drilling (⌀2–9 mm). All of it is completed in a single setup, without the part leaving the machine.

The variant with the highest length-to-diameter ratio is OTOA-GPN-04: 16 mm long at ⌀4 mm, L/D 4.0. This ratio is achievable on a conventional lathe as well; the sliding-head advantage in series work is that the part never leaves the machine, so the size does not drift from variant to variant.

Variants are machined to h6 tolerance; the smallest is OTOA-GPN-04 (⌀4 mm) and the largest OTOA-GPN-16 (⌀16 mm). The family includes bored variants. Custom sizes, tolerances or materials are produced to the part code on request.
