Key statement: The shock absorber includes a flee floating pressure tube that is able to expand or contract axially without breaking a seal, a hybrid piston rod with a shaft of one material that compensates for differing thermal expansions and a cap of another material that absorbs axial forces, a unique rod guide assembly with a biasing member that compensates for differing thermal expansion, and a unique cylinder end assembly with a biasing member made from springs, a rubber block or pressurized gas.
We're working right now with our high pressure forming operation to provide formed high pressure tube, in the neighborhood of 3500 psi.
The thru-bore pressure tube design provides for the best possible alignment, beating life, and operation at speeds of up to 5,000 RPM.
