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
Rocker Arm Pin is a Automotive Precision Parts family precision-turned on a Goodway SW-20, covering 9 variants — diameters ⌀5–12 mm, lengths 30–56 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 OTOA-RKR-12 at 56 mm. Besides turning, the family requires thread turning (5 sizes from M5 to M12), hex flat milling (AF 10), knurling and axial drilling (⌀4 mm). All of it is completed in a single setup, without the part leaving the machine.
The most slender variant is OTOA-RKR-05: 30 mm long at ⌀5 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 6g, h8 tolerance classes; the smallest is OTOA-RKR-05 (⌀5 mm) and the largest OTOA-RKR-12S (⌀12 mm). The family includes threaded, hex-drive, knurled, bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
