Bore 20 / M20 X 1.5 ThreadJFR20M JFL20M 20 M20 X 1.5 Carbon Steel Female Rod End (Metric)
JM M JF M Product Overview
JFR20M / JFL20M is a three-piece precision metric female rod end with a 20 mm bore (B) and 46 mm body housing diameter (D). The 34.93 mm 52100 steel ball is precision ground, heat treated, and hard chrome plated, seated in an alloy steel precision race with PTFE liner option. Female body length (AF) is 77 mm, thread engagement (CF) is 40 mm, body width (W) is 25 mm, body thickness (T) is 18.0 mm. Approximate weight: 350 g.
Rated at 50,955 N static radial load with ±20° misalignment angle, this M20 X 1.5 internally threaded female rod end suits heavy-duty industrial machinery, agricultural implements, and large actuator systems. The female body threads onto a mating stud or tube adapter, functioning as the pivot end of a rod-end linkage assembly. Three-piece precision construction; carbon steel body with yellow zinc plating.
Available in right-hand (JFR20M) and left-hand (JFL20M) metric thread configurations. PTFE-lined version (add ‘T’ suffix, e.g., JFR20MT) for maintenance-free operation. Studded versions (add ‘S’ suffix) also available. Alternate thread pitch variants available on request. Silver zinc plating option available; inch equivalent is the JF series.

JM M JF M Frequently Asked Questions
What is the difference between JM-M and JF-M rod ends?
JM-M parts are male rod ends with an external metric thread, while JF-M parts are female rod ends with an internally threaded body. Both belong to the same 3-piece yellow-zinc-plated carbon steel metric series.
What materials are used in the JM-M-JF-M metric series?
The series uses a heat-treated, hard-chrome-plated 52100 bearing steel ball, an alloy steel race with PTFE lining optional, and a yellow-zinc-plated carbon steel body.
Are different thread pitches available in the JM-M-JF-M series?
Yes. Selected sizes offer alternate pitch options, and special suffixes can also designate studded or PTFE-lined variations depending on the required part configuration.
Can I order studded or PTFE-lined versions in this metric series?
Yes. Studded configurations are available by adding an S suffix, and PTFE-lined versions are available by adding a T suffix, subject to the exact size and part configuration.
What types of machinery use JM-M and JF-M rod ends?
This metric series is commonly used in motorsport suspension systems, steering linkages, agricultural machinery, industrial automation assemblies, and other motion-control linkages built around metric hardware standards.
Is there an inch equivalent for the JM-M-JF-M metric series?
Yes. The inch equivalent is the JM-JF series. If your build uses imperial hardware, the JM and JF family is the closest companion line to review alongside JM-M and JF-M.
