Material & Tolerance
The standard material is listed below; also available in steel, stainless, brass and aluminium. Dimensions in mm; tolerances machined to ISO. Deviations (mm) are given for the nominal diameter according to the ISO 286-2 tables; thread tolerances (6g/6H) are to ISO 965. For custom sizes/tolerances, contact us with the part code.
Manufacturing Scope
Bearing Spacer Ring is a Bearing & Seal Adapters family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀8–20 mm, lengths 4–12 mm, standard material Steel (also stainless steel, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request a quote with the code you need.
The family is machined from ⌀20 mm bar stock; its longest variant is RULA-ABL-12L at 12 mm. The family is produced by turning alone. 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 RULA-ABL-12L: 12 mm long at ⌀14 mm, L/D 0.9. 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 RULA-ABL-06 (⌀8 mm) and the largest RULA-ABL-17 (⌀20 mm). The family includes bored variants. Custom sizes, tolerances or materials are produced to the part code on request.
