Washers Bushings Rings Shims Spacers

Washers, Bushings, Rings, Shims and Spacers are listed in this category. They are used extensively in aerospace but also in other industrial applications. They are offered as OEM products or as part of our own labelled (AVIATIONEU NEW ERA) product lines in different materials, sizes and standards/specifications.

Aircraft washers are used in airframe structures. They come in different international Standards including US Army-Navy (AN), NAS or MS, German (DIN) and DIN - Aerospace Standards (LN), European (EN), French NFL, NSA, PAN, TAN and others.  They usually include plain (such as AN960 and AN970)and lock (such as AN935 and AN936) washers. The first (plain washers) are used for nuts to protect the metal from being scratched when the nut is turned down. They also may be used as a shim under a nut to compensate for a bolt that is slightly long. The second (lock washers) come in various designs and used to hold the nut under tension on a bolt to prevent its turning. The most common type is split lock washers made of heavy spring steel, split, and twisted with teeth cut into the inner circumference or in the outer circumference. Other types of washers are also used such as NAS143 and MS20002 washers for internal wrenching bolts of the NAS144 through NAS158 series.

Aircraft bushings are isolator bearings that are designed for use with rotating parts. In airplanes, they allow parts to rotate without the need for lubricants.

Aircraft retaining rings help holding mating components or assemblies together. They sit in a groove (housing or shaft) and can be internal (housing) or external (shaft) retaining ring types.

Aircraft shims are thin pieces of material used to fill gaps in bolted joints.

Aircraft spacers are used to secure wiring, tubing, and ducting away from the aircraft structure.
