Suitable for many light to heavy duty industrial/mechanical motion transfer applications, the Tuthill 2-piece metal to metal EM-M/EF-M Series offers an economical design in metric sizing. Ball and body materials are produced from low carbon steel and are zinc plated with yellow dichromate treatment for extended corrosion resistance. The ball is also case hardened for extended wear. (Optional PTFE liner minimizes wear, reduces maintenance and increases rod end life — self-lubricating and moisture resistant,as well. Ball on PTFE version is electroless nickel plated.) This all metal rod end can be operated in a wide range of temperatures. Studded, PTFE lined and right or left-handed thread versions are available. Grease fittings are optionally available on metal to metal series.
