Bore 0.3750 / 3/8-24 ThreadJFR6(T) / JFL6(T) features a 0.3750″ bore (B) and 1.000″ body diameter (D). Overall body length (AF) is 1.625″, thread engagement (CF) measures 0.937″. Width (W) is 0.500″ and body thickness (T) is 0.406″. Approximate weight: 0.150 lbs.
Rated at 3,915 lb static radial load with ±12° misalignment angle, this female rod end with a 3/8-24 UNF 3A internal thread suits general industrial linkages, suspension components, and control assemblies. The heat-treated carbon steel body with yellow zinc plating provides reliable corrosion resistance for industrial and automotive applications.
Available as a standard version (JFR6 / JFL6) or PTFE-lined (JFR6T / JFL6T) 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.

The JFR6(T) / JFL6(T) is a 0.3750" bore, 3/8-24 UNF 3A internal-thread female rod end in the JM(-T)-JF(-T) series, sized for general industrial linkages, suspension components, and control assemblies.
Bore (B) is 0.3750" and the internal thread is 3/8-24 UNF 3A, with an overall body diameter (D) of 1.000".
The JFR6(T) / JFL6(T) is rated at 3,915 lb static radial load with up to ±12° of angular misalignment.
Overall body length (AF) is 1.625", thread engagement (CF) measures 0.937", width (W) is 0.500", and body thickness (T) is 0.406" — approximate weight is 0.150 lb. Confirm these dimensions against your mounting clearance before ordering.
Ball: 52100 bearing steel, precision ground, heat treated, hard chrome plated. Body: Carbon steel, yellow zinc plated. Race: Alloy steel, PTFE lined optional.
Yes — alongside the standard version (JFR6 / JFL6), SYZ offers a PTFE-lined -T version (JFR6T / JFL6T) for maintenance-free, lubrication-free operation. A stud option (suffix S) and a grease-fitting option (suffix Z) are also available; confirm the exact suffix combination you need when requesting a quote. Technical drawing 72443 is available on request.
