Spherical Linkage Products - Motion Transfer Product Supplier

Your Single Source for Motion Transfer Linkage Products

Aetna has supplied spherical linkage products for demanding applications since 1963. As a motion transfer linkage product supplier, we stock and manufacture parts in standard and per-print configurations, so engineers and purchasing teams can source a complete motion transfer system from one place. Consolidating these parts with one supplier reduces purchase orders and keeps your motion transfer hardware consistent across every order.

Our spherical linkage product range includes:

Standard Rod End Construction

Aetna parts are made from a range of materials matched to the application. Our standard spherical rod ends use 1045 steel bodies, surface-hardened and trivalent zinc-plated, with hard-chrome plated 52100 bearing steel balls for wear resistance and corrosion protection.

Custom Linkage Assemblies

Many applications call for parts built to a unique print. Aetna works from your drawing or sample to produce custom linkage assemblies and control rods sized for the load and travel your design requires. Tell us the application, and our team will recommend a configuration and material set. For unique requirements, we manufacture to print and support PPAP Requirement Levels 1 through 3.
