Reducing Sleeve
Stepped reducing sleeve adapting a shaft to a larger bore.
Manufacturing Scope
Reducing Sleeve is a Bearing & Seal Adapters family precision-turned on a Goodway SW-20, covering 8 variants — diameters ⌀14–20 mm, lengths 16–30 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 ⌀20 mm bar stock; its longest variant is RULR-RED-17 at 30 mm. Besides turning, the family requires taper turning. Bores in this family run ⌀6–17 mm. All of it is completed in a single setup, without the part leaving the machine.
The variant with the highest length-to-diameter ratio is RULR-RED-17: 30 mm long at ⌀20 mm, L/D 1.5. A short, rigid body: what governs the result here is not deflection but diameter tolerance and surface finish.
Variants are machined to h7 tolerance; the smallest is RULR-RED-06 (⌀14 mm) and the largest RULR-RED-17 (⌀20 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.
