Suitable for many light and heavy/medium industrial/mechanical motion transfer applications requiring metric thread sizing, the Tuthill MJ-M/FJ-M 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 the ball is nickel plated for improved corrosion resistance (ball is also case hardened for extended wear). The body is yellow dichromate treated for extended corrosion resistance. 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.
