Rod ends in the SKF SAL ES line are spherical units with a male threaded shank. They carry load while permitting rotation and angular misalignment between linked components, which makes them useful wherever a mechanism has to tilt or pivot rather than run in a straight line. MR Industrial Accessories LLC supplies this series to maintenance and purchasing teams, and quotes are handled by part number through WhatsApp or email.
Reading the code is straightforward. SAL tells you it is a spherical rod end with a male shank. The figure in the middle is the nominal bore in millimeters, so SAL 15 ES and SAL 30 ES sit at opposite ends of the range shown here. ES closes the code and identifies a standard version whose sliding surfaces are treated steel. Every item in the series follows that same pattern.
Typical installations include hydraulic and pneumatic cylinders, valve linkages, steering rods, suspension on mobile machinery, material handling systems, presses, cranes and conveyors. The job they do is to take up misalignment so the surrounding supports are not loaded with forces they were not designed for.
Selection comes down to a few checks: bore diameter, thread type, and whether the movement is back-and-forth or continuous. Environment matters too. Dust or moisture calls for protection such as bellows or seals, and the lubricant has to suit the surface material and be renewed at the interval the service demands. When fitting, line the shank up with the load and keep impacts away from the cage and seat.
Interchange with other brands is possible when the dimensional designation matches, though load capacity and surface treatment are not necessarily the same from one design to another. Compare the full code and the operating conditions before swapping a part out. If the marking is worn, a photo or the original sample is enough for us to work from.
Send the code you need, for example SAL 20 ES or SAL 25 ES, by WhatsApp or email. Our team comes back with a quote and can point you to equivalent options or help confirm dimensions when you are unsure.

Frequently asked questions
- What does the ES suffix tell me about a SAL rod end?
- It marks a standard version with treated steel sliding surfaces and built-in lubrication. The main dimensions stay the same as other designs in the series, but the contact type and the maintenance routine differ. Confirm the complete code before ordering a replacement.
- Male thread or female thread — which one do I need?
- It depends on the connection point and the space around it. A male thread such as SAL screws into a threaded hole or nut, while a female version accepts a shank. Look at how the part sits in the existing assembly and which way the load runs.
- Can a rod end from another brand be used instead?
- Often yes, provided the main dimensions and thread type line up. Standardized designations support interchange, but load capacity, sealing and surface treatment can differ between designs. Compare the full code, and ask us if anything is unclear.
