Aerospace Rod End Bearings
Roughly 2,400 rod end bearings (heim joints) in our catalog of 266,000+ aerospace parts. Male and female threaded rod ends with self-lubricating liner options for flight control, actuation, and linkage applications, ready to order with full AS9120 traceability.
Aerospace Rod End Types
From military standard heim joints to OEM proprietary designs, we cover the male, female, and self-lubricating rod ends that keep control linkages moving.
Male Threaded Rod Ends
An externally threaded shank behind the bearing head, screwed into a control tube, clevis, or actuator. Styles such as MS21151-series rod ends, typically offered in right-hand and left-hand UNF threads so linkage length can be fine-tuned during rigging.
Female Threaded Rod Ends
An internally threaded body that accepts a threaded rod or stud end. Styles such as MS21152-series rod ends, commonly paired with a male rod end at the opposite end of a push-pull tube to form an adjustable linkage assembly.
Self-Lubricating Rod Ends
Rod ends with a bonded PTFE-type liner between ball and race, typically requiring no relubrication in service. Widely specified for flight control and actuation joints where maintenance access is limited and grease is undesirable.
OEM & Special Rod Ends
Boeing BAC style and other OEM proprietary rod ends, plus studded, sealed, and high-misalignment variants. Quote by the exact part number, including dash number, thread direction, and liner option called out on your drawing.
Rod End Materials & Design Features
Bodies, Balls & Races
Bodies are typically CRES or plated alloy steel, with balls in hardened corrosion-resistant grades. Material, finish, and load rating are set by the governing standard and dash number, so always order to the drawing callout.
Self-Lubricating Liners
PTFE-based liner systems carry oscillating loads at low friction without grease, a major advantage in control runs. Metal-to-metal variants remain in use where the drawing requires them.
Thread Direction & Adjustment
Using a right-hand rod end on one end of a tube and a left-hand rod end on the other lets riggers adjust linkage length precisely without disconnecting either joint.
Locking & Safetying
Installed rod ends are typically secured with check nuts, and many designs use witness holes to confirm minimum thread engagement. The drawing and process specification govern the details.

Rod Ends for Flight Control & Actuation Linkages
Rod end bearings sit at the joints of the systems that move an aircraft: aileron, elevator, and rudder control runs, trim systems, engine controls, door mechanisms, and actuator attachments. The spherical ball lets the joint accommodate misalignment and structural deflection while transmitting push and pull loads, which is why rod ends appear wherever a linkage must articulate through its full travel without binding.
The specification landscape combines military standards and OEM designs. Military standard families, such as MS21151-series style male rod ends and MS21152-series style female rod ends, typically cover a range of thread sizes in right-hand and left-hand versions, with self-lubricating liner variants alongside metal-to-metal designs. Boeing and other OEM drawings add proprietary rod end part numbers on top of these. Because thread direction, liner system, and dash number all change the part, Instaparts catalogs rod ends by exact part number so you can quote precisely what the drawing calls for.
Every rod end we supply moves through our AS9120 Rev B certified quality management system. Instaparts, a division of RFQ2Go, Inc. based in Toronto, Canada, sources exclusively from approved suppliers, applies counterfeit prevention controls aligned with AS6081, and ships with certificates of conformance and full lot traceability.
Linkage hardware travels in groups. The same drawings often call for aerospace pins at clevis joints, aerospace bushings in the mating fittings, and aerospace studs on adjacent attachments. For a multi-line requirement, send your bill of materials through our quote page and our team will price the complete package.
Aerospace Rod End FAQs
Is a rod end bearing the same thing as a heim joint?
Yes. Rod end bearing is the formal name for a spherical bearing housed in a threaded body; heim joint and rose joint are common shop names for the same part. Aerospace drawings call them out by standard part number, so always search and order by the exact callout rather than the generic name.
What is the difference between male and female rod ends?
A male rod end has an externally threaded shank that screws into a tube end or clevis; a female rod end has an internally threaded body that accepts a threaded rod or stud. Control tubes often pair one right-hand and one left-hand rod end so the linkage length can be adjusted like a turnbuckle.
What are self-lubricating rod ends?
Self-lubricating rod ends carry a bonded low-friction liner, typically a PTFE fabric system, between the ball and race. They are widely specified for flight control and actuation joints because they generally require no relubrication in service. The applicable standard and dash number define the liner system required.
Do you supply MS-series and OEM rod ends?
Yes. The catalog includes military standard rod ends, such as MS21151-series style parts, along with Boeing BAC style and other OEM proprietary rod ends. Search by the exact part number, including dash number and thread direction, and request a fast online quote.
What documentation comes with rod end orders?
Instaparts operates an AS9120 Rev B certified quality management system. Shipments include certificates of conformance, and lot traceability is maintained from our approved suppliers through delivery, with counterfeit prevention controls aligned with AS6081.
