Bore 0.1250 / 6-32 UNC ThreadJMR2(T) JML2(T) 0.1250 6-32 UNC Carbon Steel Male Rod End
JM(-T) JF(-T) Product Overview
JMR2(T) / JML2(T) features a 0.1250″ bore (B) and 0.500″ body diameter (D). Overall body length (AM) is 0.937″, thread engagement (CM) measures 0.562″. Width (W) is 0.250″ and body thickness (T) is 0.187″. Approximate weight: 0.013 lbs.
Rated at 500 lb static radial load with ±16° misalignment angle, this male rod end with a 6-32 UNC external thread suits light instrumentation, miniature linkages, and precision control mechanisms. The heat-treated carbon steel body with yellow zinc plating provides reliable corrosion resistance for industrial and automotive applications.
Available as a standard version (JMR2 / JML2) or PTFE-lined (JMR2T / JML2T) for maintenance-free, lubrication-free operation. Stud option (suffix S) and grease fitting option (suffix Z) available. Body is carbon steel, heat treated and yellow zinc plated; race is alloy steel for high load capacity.

JM(-T) JF(-T) Frequently Asked Questions
What is the difference between JM and JF rod ends?
JM parts are male-thread carbon steel rod ends and JF parts are female-thread carbon steel rod ends. Both belong to the same 3-piece precision series and share the same general material and performance direction.
What materials are used in the JM(-T)-JF(-T) series?
This series uses a 52100 bearing steel ball with hard chrome plating, an alloy steel race with optional PTFE liner, and a carbon steel body with yellow zinc plating. Silver zinc plated versions are also available.
What does the T suffix mean on JMR and JFR part numbers?
The T suffix identifies the PTFE-lined version. For example, JMR12T refers to the PTFE-lined version of that carbon steel rod end size.
Are studded versions available in the JM(-T)-JF(-T) series?
Yes. Studded configurations are available by adding S to the suffix, such as JMR12S, depending on the exact size and build requirement.
Are silver zinc plated versions available for this series?
Yes. In addition to the standard yellow zinc plated body, this series is also available in silver zinc plating as noted in the specification notes.
What applications are best suited to the JM(-T)-JF(-T) series?
This series is well suited to suspension systems, steering linkages, industrial motion links, agricultural equipment, and other applications that need a durable 3-piece carbon steel rod end with optional PTFE liner.
