Stepped Bearing Shaft

Bearing-and-locating shaft built from successive cylindrical steps of differing diameters.

Manufacturing Scope

Stepped Bearing Shaft is a Shafts family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀6–18 mm, lengths 44–110 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 ⌀18 mm bar stock; its longest variant is MILB-STP-10 at 110 mm. The family is produced by turning alone. All of it is completed in a single setup, without the part leaving the machine.

The most slender variant is MILB-STP-01: 44 mm long at ⌀6 mm, a length-to-diameter ratio of 7.3. 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 h7 tolerance; the smallest is MILB-STP-01 (⌀6 mm) and the largest MILB-STP-10 (⌀18 mm). The family includes multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
