Encoder Shaft
Tight-tolerance stepped precision shaft for encoder disc and bearing seating.
Manufacturing Scope
Encoder Shaft is a Shafts family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀4–14 mm, lengths 42–95 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 ⌀14 mm bar stock; its longest variant is MILB-ENC-10 at 95 mm. Besides turning, the family requires axial drilling (⌀3.3 mm). All of it is completed in a single setup, without the part leaving the machine.
The most slender variant is MILB-ENC-01: 42 mm long at ⌀4 mm, a length-to-diameter ratio of 10.5. This ratio is the very reason sliding-head lathes exist. The guide bushing supports the bar immediately beside the cutting point, so there is no deflection; the same part chatters and drifts in diameter on a conventional lathe.
Variants are machined to h6 tolerance; the smallest is MILB-ENC-01 (⌀4 mm) and the largest MILB-ENC-10 (⌀14 mm). The family includes bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
