Ask for Custom SupportSA SI Self-Lubricating Carbon Steel Rod Ends are carbon steel rod-end joints used to connect adjustable rods, control arms, brackets, and actuator members while allowing angular movement at the connection. The design combines a threaded housing around a spherical plain bearing or race so the joint can transmit movement through a compact male- or female-thread interface. Select the bore, thread, race, misalignment, load direction, and operating environment for the complete assembly rather than choosing by nominal size alone.
carbon-steel rod ends provide an adjustable articulated connection for control arms, tie rods, sway-bar links, and other force-transmitting members. Check radial load, angular travel, thread engagement, and race design before use.
The threaded male or female format can connect rods, brackets, hydraulic or pneumatic cylinders, and compact actuator mechanisms. Match thread direction, bore size, and mounting geometry to the complete linkage.
These rod ends are used in serviceable vehicle and machine linkages where alignment changes during travel. Aluminum favors low weight, while steel variants suit higher-duty assemblies; final selection should follow the actual load, motion, and environment.
Useful in vehicle and chassis linkage systems where a compact self-lubricating rod end is preferred over heavier industrial spherical joints.
A strong fit for packaging and automation equipment where repeatable articulation and reduced lubrication intervals matter.
Suitable for OEM replacement and custom metric linkage builds that need corrosion-resistant plating, studded options, and inch-series cross reference support.
SA-TK parts are male-thread rod ends and SI-TK parts are female-thread rod ends. Both belong to the same 3-piece self-lubricating metric series and share the same core material direction.
This series uses a hard-chrome-plated 52100 bearing steel ball, a copper alloy race with PTFE lining, and a carbon steel body with silver zinc plating.
Yes. The PTFE-lined copper alloy race provides self-lubricating articulation for metric linkage systems that need smoother movement and reduced maintenance.
Yes. Studded configurations are available by adding S to the suffix, for example SA12TK-S, depending on the exact size and build requirement.
Yes. The inch-size equivalent referenced in the source specification is the VM VF series, which can be reviewed when inch-thread compatibility is required.
SA-TK SI-TK rod ends are well suited to agricultural machinery, industrial motion systems, mechanical control assemblies, packaging equipment, and other metric linkages that benefit from a self-lubricating 3-piece design.
