What is BS EN 3385 – External retaining rings about?
BS EN 3385 is a European standard on aerospace series which covers rings retaining, external, axial mounting, steel, vacuum cadmium plated.
BS EN 3385 defines the characteristics of axial mounting external retaining rings, in steel, vacuum cadmium plated, for aerospace applications.
Who is BS EN 3385 – External retaining rings for?
BS EN 3385 on external retaining rings is useful for:
- Manufacturers of aerospace equipment and components
- External retaining rings manufacturers
Why should you use BS EN 3385 – External retaining rings?
External retaining rings (also known as “external snap rings”) sit in the grooves on the exterior of shafts of any size. The areas of the ring that protrude out from the shaft hold it in place.
Internal retaining rings fit into a housing or bore. External retaining rings fit over a shaft or pin. The retaining ring style can include any of the following. Circlip are the most common style for axial installation, usually has ears with holes for assembly tool.
Axial retaining rings are designed for axial installation into machined grooves. These rings are either internal for installation in housings and bores, or external, for assembly on shafts. Once installed, they provide a protrusion or “shoulder” for retaining parts.
When it comes to the manufacturing and use of aerospace components, reliability and consistent performance are crucial. Hence BS EN 3385 walks you through the characteristics of axial mounting external retaining rings, in steel, vacuum cadmium plated. This ensures safety and reliability in your organization and in turn increases the efficiency of work.
