Stepped Spacer Ring
Stepped spacer with two diameters seating inner and outer bearing races separately.
Manufacturing Scope
Stepped Spacer Ring is a Bearing & Seal Adapters family precision-turned on a Goodway SW-20, covering 9 variants — diameters ⌀12–20 mm, lengths 11–30 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 RULA-KDM-12L at 30 mm. The family is produced by turning alone. Bores in this family run ⌀6–15 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 RULA-KDM-12L: 30 mm long at ⌀18 mm, L/D 1.7. A short, rigid body: what governs the result here is not deflection but diameter tolerance and surface finish.
Variants are machined to h8 tolerance; the smallest is RULA-KDM-06 (⌀12 mm) and the largest RULA-KDM-15 (⌀20 mm). The family includes 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.
