Suitable for many light and heavy/medium duty industrial/mechanical motion transfer applications, Tuthill's most popular rod end series, the SPM/SPF Series offers an injection-molded, reinforced nylon raceway design. It delivers low maintenance, self-lubricating characteristics, as well as moisture-resistance properties adding to its overall versatility. Ball and body materials are produced from an economical low carbon steel and are zinc plated with yellow dichromate treatment for extended corrosion resistance (ball is case hardened for extended wear). Suited for applications requiring low friction, low moisture absorption, high wear resistance and/or wide operating temperature ranges. Studded and right or left-handed thread versions are available.
