Mil. Spec. Ball Joint Rod Ends
 |
 |
Made of cadmium-plated steel, these rod ends generally handle higher loads than stainless steel, aluminum, and nylon rod ends. They provide moderate corrosion resistance. All have a PTFE liner that allows smooth ball rotation and eliminates the need for lubrication. Liner meets SAE AS81820.
Oversized Shank—Rod ends with an oversized shank have a shank that is one size larger than the ID to handle greater stress.

High-Speed Ball Bearing Rod Ends
 |
|
A double row of precision ball bearings allows high speeds and smooth operation. Rod ends are made of cadmium- or zinc-plated steel, which both offer moderate corrosion resistance. Seals keep lubricant in and dirt out.
Oversized Shank—Rod ends with an oversized shank have a shank that is one size larger than the ID to handle greater stress.
Cadmium-Plated Alloy Steel—Cadmium-plated steel rod ends have lubricant that meets MIL-PRF-81322. They won’t require ongoing lubrication.

Internally Threaded Ultra-Precision Ball Joint Rod Ends
 |
|
Made to extremely tight tolerances, these rod ends are for applications that require positioning accuracy, such as accelerators and other types of control linkages. Rod ends are steel and generally handle higher loads than stainless steel, aluminum, and nylon rod ends. They have a heat-treated steel ball for added strength and a brass insert for smooth operation. They come lubricated, so you won't need to lubricate them at installation. They will require ongoing lubrication.
Cadmium-Plated Carbon Steel—Zinc- and cadmium-plated rod ends provide moderate corrosion resistance.
