Tailored component shape and properties

Objective: remove unnecessary material without loss of damper performance or fatigue life.

BWI Group offers these products in the area of tailored component shape and properties:

• Hollow piston rod
• One piece knuckle bracket
• Reservoir tube with variable wall thickness

Hollow piston rod

Piston rod size is primarily determined based upon the expected level of lateral force (bending moments). The majority of the stresses are supported by extreme fibers of the rod, leading to the potential to replace the solid piston rod structure by a tube without significant loss of strength or stiffness. Production technology is available in a variety of diameters from 18mm to 25mm, along with various tube thicknesses.
