Injector Pin
Precision cone-tipped pin guiding needle/valve motion in fuel injectors.
Manufacturing Scope
Injector Pin is a Automotive Precision Parts family precision-turned on a Goodway SW-20, covering 8 variants — diameters ⌀4–10 mm, lengths 21–52 mm, standard material Stainless 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 ⌀10 mm bar stock; its longest variant is OTOA-INJ-10 at 52 mm. Besides turning, the family requires taper turning and axial drilling (⌀2–3 mm). All of it is completed in a single setup, without the part leaving the machine.
The most slender variant is OTOA-INJ-04L: 36 mm long at ⌀4 mm, a length-to-diameter ratio of 9.0. 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 h6 tolerance; the smallest is OTOA-INJ-04 (⌀4 mm) and the largest OTOA-INJ-10 (⌀10 mm). The family includes tapered, bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
This is a dimension schematic, not a manufacturing drawing. Dimensions match the catalog data; request a quote with the part code to confirm before production.
