Expanded Bushing in metallic parts
Expanded bushing (EB) simultaneously coldworks the material around the hole, and provides a high interference fit
Expanded bushing offers several advantages :
- Improved Fatigue Life
- Fatigue life superior to press or shrink fit installations
- One-Sided Operation
- Process accomplished within seconds
- Corrosion Resistance
- Protective coatings are not damaged during installation
- High Torque and Pushout Resistance
- Greater resistance to rotation and pushout compared to conventional installation methods
- Installation is Safer and Quicker
- Cryogenic fluid not required
Expanded bushings can be used for most bushing installations. Bushings are available in a number of materials and configurations:
Configurations
- Large range of Bushing inside diameter : from 10mm to more than 100 mm
- Bushing geometry : Straight and flanged – Lube grooves and holes
- Bushing material: Bronze, Titanium, Steels, Beryllium-copper, Aluminium, Nickel…
- Parent material: Aluminum, Steel, Titanium…

Anti-fretting coating
Capaero is able to design bushings with an anti-fretting coating (Browncoat). This is widely used on helicopter applications and offer a reliable protective solution.
Expanded Bonded Bushing in composite panels
Expanded Bonded Bushing produces fretting and adhesive load tranfer. It improve the assembly performance and the installation process.
EB² bushings are coated during manufacturing with a micro-encapsuled adhesive. During the installation, the process is very simple: bushing is sliped on a mandrel and coldexpanded into the hole. Both fretting and adhesive provide a high performance load transfer between the bushing and the composite panel.
We propose a full package from design and stress calculation to bushing installation. The EB² (Expanded Bonded Bushing) with the encapsuled adhesive:
- doesn’t required adhesive stock in assembly
- has a high resistance to torque and push-out
- Increase in load transfer allowable for composite material
- can be with straight or flanged bushing
- can use any material
- Ease installation (No manual adhesive coating)
- is an optimized and repetitive process
- reduces operator skilled level required
