SAE J1120 Male Spherical Rod End Bearings

Male Spherical Rod End Bearings

Aetna Screw is a certified SAE J1120 male rod end bearing manufacturer supplying OEMs, distributors, and industrial engineers worldwide. Our male spherical rod end bearings — also known as heim joints in motorsports and automotive applications — deliver superior self-alignment, low friction, and extended wear life across the most demanding operating environments. Available in multiple series, material compositions, and protective coatings, Aetna's male rod ends are precision-engineered to meet strict dimensional tolerances and interchangeable SAE J1120 specifications. Custom per-print configurations and PPAP support are available upon request.

Male Rod End Bearing Series & Specifications

Available series: ASPM | ACM | ACM-T | AMAX-T | SSM-T — Industrial & Commercial Grade, 2-Piece Construction 

All male spherical rod end bearings are designed and manufactured to SAE J1120 specifications for full interchangeability across industrial and commercial applications. 

• ASPM, ACM, ACM-T & AMAX-T series: Spherical ball manufactured from 52100 bearing steel — precision ground, surface hardened for wear resistance, and hard chrome plated for corrosion protection. 
• Rod end body manufactured from 1045 steel with a minimum 0.0003" RoHS-compliant Trivalent zinc plating. ASPM series includes an additional Yellow Dichromate topcoat for enhanced corrosion resistance. 
• AMAX-T series: Rod end body constructed from high-alloy steel with a Black Oxide finish for heavy-duty and high-load applications 
• SSM-T series: Spherical ball manufactured from 440C Stainless Steel — precision ground and surface hardened. Rod end body constructed from 300-series Stainless Steel, ideal for corrosive or washdown environments. 
• Left-hand threads are available across all sizes and series. Left-hand units are clearly marked for easy identification during installation. 
• To order left-hand thread, add the suffix "L" to your part number (e.g., ASPML8).
• All coating and plating options are available upon request. Please provide your coating specifications when contacting us — our team will confirm compatibility and lead times.

Male Rod End Bearing Applications

Aetna's SAE J1120 male spherical rod end bearings — engineered for precision motion control and misalignment compensation — serve critical roles across a wide range of industries:

• Heavy Machinery & Construction: Withstands high radial and axial loads in excavators, cranes, and loaders where structural durability is non-negotiable.
• Motorsports & Automotive: Used as heim joint rod ends in suspension, steering, and throttle linkages where precise control and reliability are essential.
• Industrial Automation & Robotics: Enables smooth, repeatable motion in robotic arms, actuators, and automated assembly systems.
• Aerospace & Defense: Meets tight dimensional tolerances required for control linkages in demanding, mission-critical environments.
• Material Handling: Supports reliable load transfer and angular misalignment compensation in conveyors, hoists, and lifting equipment.
• Agriculture & Forestry: Performs under heavy cyclic loading in tractors, harvesters, and implement linkages operating across variable terrain.
