Bore 8 / M8 X 1.25 ThreadJMR8M / JML8M is a three-piece precision metric male rod end with a 8 mm bore (B) and 22.25 mm body housing diameter (D). The 15.88 mm 52100 steel ball is precision ground, heat treated, and hard chrome plated, seated in an alloy steel precision race with PTFE liner option. Body length (AM) is 42 mm, thread shank engagement (CM) is 25 mm, body width (W) is 12 mm, body thickness (T) is 8.75 mm. Approximate weight: 31 g.
Rated at 13,595 N static radial load with ±18° misalignment angle, this M8 X 1.25 threaded male rod end suits general industrial machinery, packaging equipment, and agricultural equipment linkages. The three-piece precision construction provides tighter dimensional control compared to two-piece designs, making the JM-M series a practical step up for applications that demand consistent articulation under varying load cycles. Carbon steel body with yellow zinc plating.
Available in right-hand (JMR8M) and left-hand (JML8M) metric thread configurations. PTFE-lined version (add ‘T’ suffix, e.g., JMR8MT) for self-lubricating, maintenance-free operation. Studded versions (add ‘S’ suffix) also available. Alternate thread pitch variants available on request. Silver zinc plating option available; inch-thread equivalent is the JM series.

The JMR8M / JML8M is a three-piece precision metric male rod end with 8 mm bore and M8 X 1.25 thread, built for very heavy-duty structural linkages, large industrial machinery, and high-load pivot assemblies.
Bore (B) is 8 mm, body housing diameter (D) is 22.25 mm, body length (AM) is 42 mm, thread shank engagement (CM) is 25 mm, body width (W) is 12 mm, and body thickness (T) is 8.75 mm. Approximate weight is 31 g.
The JMR8M is rated at 13,595 N static radial load with ±18° misalignment angle.
The 15.88 mm ball is 52100 bearing steel, precision ground, heat treated, hard chrome plated, seated in an alloy steel precision race with a PTFE liner option. The body is carbon steel, yellow zinc plated.
JMR8M is the right-hand thread version and JML8M is the left-hand thread version of the same 8 mm male rod end — order the pair to match your linkage's thread-hand requirements.
Yes — add a 'T' suffix (e.g., JMR8MT) for a PTFE-lined, maintenance-free version; a studded version is available by adding an 'S' suffix; alternate thread pitch variants and silver zinc plating are available on request; the inch-thread equivalent is the JM series.
