SKF SA E series rod ends are radial spherical plain bearings with a male threaded shank. They handle radial loads while allowing oscillating and misalignment movement, which makes them useful in hydraulic cylinders, steering linkages and suspension systems. The treated steel sliding surface suits demanding industrial service. MR Industrial Accessories LLC supplies this series as part of its bearing range for customers in the United States and Latin America.
Reading the code is straightforward. The letters SA identify a rod end with a male threaded shank. The number that follows is the nominal bore diameter in millimeters, as seen in SA 6 E, SA 8 E, SA 10 E and SA 12 E. The suffix E denotes a treated steel sliding surface, a version built for higher loads than the standard design. With this structure, a maintenance or purchasing team can confirm size and version from the part number alone.
These rod ends appear in hydraulic and pneumatic cylinders, steering joints, suspension systems, agricultural machinery, material handling equipment and automation systems. They are chosen where force has to be transmitted at varying angles, including robotic arms, presses and lifting mechanisms. Because they oscillate without constant attention, they fit continuous production environments.
Selection depends on shaft diameter, thread type (male or female), expected radial and axial load, and the surrounding conditions. Sealing matters: sealed versions keep out dust and moisture and help extend service life. During assembly, align the components correctly and avoid striking the spherical plain bearing. Initial lubrication is generally sufficient, though severe applications may call for periodic greasing.
SKF SA E rod ends can be interchanged with products from other manufacturers that use the same dimensional designation, such as SA...E series from other brands. Tolerances and load capacities can differ, so interchangeability is not automatic; check the technical specifications of each alternative. MR Industrial Accessories LLC can advise on compatibilities and suggest equivalents.

Frequently asked questions
- What does the E suffix mean in SA E bearings?
- The E suffix indicates a treated steel sliding surface, which allows the rod end to withstand higher loads than the standard version. It matters in applications with greater mechanical demands.
- How do I choose between a male and a female rod end?
- The choice depends on the mounting. A male rod end has a threaded shank that inserts into a threaded hole, while a female rod end has an internal thread that receives a bolt. Consider the available space and the fastening method.
- How often are these bearings lubricated?
- Lubrication frequency depends on working conditions. In normal applications, the initial lubrication can last a long time; in dirty or high-load environments, periodic greasing is recommended according to the manufacturer's instructions.
