Bore 12 / M12 X 1.75 ThreadMPMR12 MPML12 12 M12 X 1.75 Carbon Steel Male Rod End (Metric)
MPM MPF Product Overview
MPMR12 / MPML12 is a metric self-lubricating male rod end with a 12 mm bore (B) and 32 mm body housing diameter (D). The 22.20 mm 52100 steel ball is precision ground, heat treated, and hard chrome plated, running in an injection-molded reinforced nylon race with PTFE for maintenance-free operation. Body length (AM) is 54 mm, thread shank engagement (CM) is 33 mm, body width (W) is 16 mm, body thickness (T) is 12.0 mm. Approximate weight: 110 g.
Rated at 19,000 N static radial load with ±13° misalignment angle, this M12 X 1.75 threaded male rod end suits mid-duty industrial machinery, agricultural equipment, and self-lubricating pivot systems. The reinforced nylon+PTFE race eliminates the need for lubrication, making MPM rod ends a practical choice wherever maintenance access is limited. Carbon steel body with yellow zinc plating.
Available in right-hand (MPMR12) and left-hand (MPML12) metric thread configurations. Studded version (add ‘S’ suffix) also available. Alternate thread pitch variants available on request. Silver zinc plating option available; inch-thread equivalent is the PM series.

MPM MPF Frequently Asked Questions
What is the difference between MPM and MPF rod ends?
MPM parts are male-thread rod ends and MPF parts are female-thread rod ends. Both belong to the same precision molded-race self-lubricating metric series and share the same core material direction.
What materials are used in the MPM-MPF series?
This series uses a hard-chrome-plated 52100 bearing steel ball, an injection molded reinforced nylon race with PTFE, and a carbon steel body with yellow zinc plating.
Is the MPM-MPF series self-lubricating?
Yes. The molded nylon race provides self-lubricating operation, which is one of the defining characteristics of the MPM-MPF series.
Are studded versions available in the MPM-MPF series?
Yes. Studded configurations are available by adding S to the suffix, such as MPMR12S, depending on the exact size and build requirement.
Are silver zinc plated versions available?
Yes. In addition to the standard yellow zinc plated body, this series is also available in silver zinc plating as noted in the product notes.
What applications are best suited to MPM-MPF rod ends?
MPM-MPF rod ends are well suited to control linkages, packaging machinery, agricultural equipment, general mechanical assemblies, and other lighter-duty systems that benefit from a self-lubricating molded-race design.
