Material & Tolerance
The standard material is listed below; also available in steel, stainless, brass and aluminium. Dimensions in mm; tolerances machined to ISO. Deviations (mm) are given for the nominal diameter according to the ISO 286-2 tables; thread tolerances (6g/6H) are to ISO 965. For custom sizes/tolerances, contact us with the part code.
Manufacturing Scope
Knurled Press-Fit Pivot Pin is a Joint & Pivot Elements family precision-turned on a Goodway SW-20, covering 9 variants — diameters ⌀3–12 mm, lengths 18–55 mm, standard material Steel (also stainless steel, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request a quote with the code you need.
The family is machined from ⌀12 mm bar stock; its longest variant is MAFA-KPV-12 at 55 mm. Besides turning, the family requires knurling. All of it is completed in a single setup, without the part leaving the machine.
The most slender variant is MAFA-KPV-03: 18 mm long at ⌀3 mm, a length-to-diameter ratio of 6.0. A part this slender needs tailstock support on a conventional lathe. On a sliding-head lathe the guide bushing holds the bar right next to the cutting edge, so the part is machined without a centre.
Variants are machined to h9 tolerance; the smallest is MAFA-KPV-03 (⌀3 mm) and the largest MAFA-KPV-12 (⌀12 mm). The family includes knurled, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
