Bore 0.1900 / 10-32 ThreadPFR3 PFL3 0.1900 10-32 Carbon Steel Female Rod End
PM PF Product Overview
PFR3 / PFL3 features a 0.1900″ bore (B) and 0.625″ body diameter (D), with a 0.437″ precision-ground 52100 steel ball running in an injection-molded nylon race. Overall body length (AF) is 1.062″, thread engagement (CF) measures 0.562″. Width (W) is 0.312″ and body thickness (T) is 0.250″. Approximate weight: 0.040 lbs.
Rated at 1,220 lb static radial load with ±13° misalignment angle, this female rod end with a 10-32 UNF 3A internal thread suits light-duty linkages, control systems, and precision instrumentation. The injection-molded nylon race is self-lubricating by design — no grease fittings or maintenance schedule required, making this rod end ideal for sealed or hard-to-service installations.
Available in right-hand (PFR3) and left-hand (PFL3) thread configurations. Stud configuration available (add suffix S, e.g. PFR3-S). Silver zinc plating available on request for enhanced corrosion protection. Body is carbon steel, heat treated and yellow zinc plated; ball is 52100 bearing steel, hard chrome plated.

PM PF Frequently Asked Questions
What is the difference between PM and PF rod ends?
PM parts are male-thread rod ends and PF parts are female-thread rod ends. Both belong to the same precision molded-race self-lubricating series and share the same core material direction.
What materials are used in the PM-PF series?
This series uses a hard-chrome-plated 52100 bearing steel ball, an injection molded nylon race, and a carbon steel body with yellow zinc plating.
Is the PM-PF series self-lubricating?
Yes. The molded nylon race provides self-lubricating operation, which is one of the defining characteristics of the PM-PF series.
Are studded versions available in the PM-PF series?
Yes. Studded configurations are available by adding S to the suffix, such as PMR12-S, 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 PM-PF rod ends?
PM-PF 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.
