Suitable for many light to heavy duty industrial/mechanical motion transfer applications, the Tuthill 2-piece metal to metal EM/EF Series offers our most economical design. Ball and body materials are produced from a low carbon steel and are zinc plated with yellow dichromate treatment for extended corrosion resistance. The ball is case hardened for extended wear. This all metal rod end can be operated in a wide range of temperatures. Studded and right or left-handed thread versions are available. Grease fittings are optionally available.
