Afstandsring

Afstandsring is a ring-shaped mechanical component with a central bore that is used to create axial spacing between two parts in an assembly. Its primary purpose is to set distance, locate components along a shaft or bore, compensate for dimensional variations, and sometimes to preload bearings or align pulleys, gears, or housings.

Materials and geometry commonly found for afstandsring include metals such as steel, stainless steel, and aluminum, as well as plastics or composite materials. The key dimensions are the inner diameter (matching the shaft or through-bolt), the outer diameter (determining the space the ring occupies within the assembly), and the thickness (the amount of spacing provided). Tolerances and finishes vary with application and material.

Designs of afstandsring range from simple solid spacers to threaded spacers and shoulder spacers. A basic spacer is a plain cylindrical ring, while a threaded spacer includes holes or through-bores for bolts or screws, and a shoulder spacer features a raised portion that locates against a bearing face or housing. Spacers are often chosen to be compatible with standard fastening geometries and may be selected from standard catalog sizes or produced as custom parts.

Applications span automotive, machinery, and consumer equipment, where spacers position bearings, gears, pulleys, or sprockets on shafts, or space components within housings. Proper selection considers inner diameter fit, axial spacing needs, material compatibility, and mechanical load requirements. Installation typically involves aligning the bore with the shaft or fastener, ensuring adequate seating, and securing with appropriate hardware as required.
