Bore 20 / M20 X 1.5 ThreadJFXR20M JFXL20M 20 M20 X 1.5 Chromoly Steel Female Rod End (Metric)
JMX M JFX M Product Overview
JFXR20M / JFXL20M 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 a heat-treated alloy steel 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 120,210 N static radial load with ±20° misalignment angle, the JFX-M series provides significantly higher load capacity than standard carbon steel metric female rod ends through heat-treated alloy steel construction. This internally threaded M20 X 1.5 female rod end suits heavy-duty industrial machinery, large agricultural equipment, and structural pivots. The female body threads onto a mating stud or tube adapter; alloy steel body with silver zinc plating.
Available in right-hand (JFXR20M) and left-hand (JFXL20M) metric thread configurations. PTFE-lined version (add ‘T’ suffix, e.g., JFXR20MT) for maintenance-free operation. Studded versions (add ‘S’ suffix) also available. Polished hard chrome finish and alternate thread pitch variants available on request. Inch-thread equivalent is the JFX series.

JMX M JFX M Frequently Asked Questions
What is the difference between JMX-M and JFX-M rod ends?
JMX-M parts are male rod ends with an external metric thread, while JFX-M parts are female rod ends with an internally threaded body. Both belong to the same 3-piece heat-treated chromoly metric series.
What materials are used in the JMX-M-JFX-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 silver-zinc-plated heat-treated alloy steel body.
Are different thread pitches available in the JMX-M-JFX-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 JMX-M and JFX-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 JMX-M-JFX-M metric series?
Yes. The inch equivalent is the JMX-JFX series. If your build uses imperial hardware, the inch JMX and JFX family is the closest companion line to review alongside JMX-M and JFX-M.
