Eccentric Pin

Manufacturing Scope

Eccentric Pin is a Automotive Precision Parts family precision-turned on a Goodway SW-20, covering 8 variants — diameters ⌀6–16 mm, lengths 22–44 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-ECC-16C at 44 mm. Besides turning, the family requires thread turning (M5) and hex flat milling (AF 13). 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-ECC-08T: 32 mm long at ⌀8 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 h7, 6g tolerance classes; the smallest is OTOA-ECC-06 (⌀6 mm) and the largest OTOA-ECC-16C (⌀16 mm). The family includes threaded, hex-drive, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
