SKF SI ES rod end bearings are radial spherical plain bearings that use a female thread. They handle radial loads while allowing oscillating and misalignment movement, which makes them suitable for hydraulic cylinders, steering linkages and transmission mechanisms. MR Industrial Accessories supplies this line and can help you match the correct size to your equipment.
The code breaks down simply: SI means a rod end bearing with a female thread, the number is the bore diameter in millimeters, and ES identifies the steel-cage design with standard lubrication. So SI 15 ES has a 15 mm bore, SI 20 ES has a 20 mm bore, and so on. Reading the code this way tells you both size and mounting style at a glance; the female thread accepts a threaded rod or pin.
You will find these bearings in metalworking, automotive, agricultural and construction equipment. Typical locations include hydraulic cylinders on road machinery, vehicle steering, suspension arms and other oscillating assemblies. They also appear in sliding doors, actuators and lifting mechanisms where repetitive angular movement and misalignment must be absorbed.
When choosing a bearing, check bore diameter, thread type (female or male) and the load conditions of the application. The SI ES series is lubricable and built with a steel cage. During installation, keep alignment correct and avoid pure axial loads. In dusty or wet environments, add seals. Regular lubrication helps extend service life, particularly where motion is continuous.
Interchangeability is common because rod end bearings follow international standards for dimensions. Codes differ between makers, but a bearing with matching dimensions and thread type is normally compatible. Confirm tolerances and radial clearance before substituting. Our team can review interchange options so your equipment keeps performing as intended.
To replace a rod end bearing, send the complete code by WhatsApp or email. We quote the SI ES series and help you confirm the exact size and thread type for your machine. We also suggest equivalents when needed.

Frequently asked questions
- What does the SI ES designation mean?
- SI stands for a rod end bearing with a female thread. ES indicates the steel-cage design with standard lubrication. The number in the middle is the bore diameter in millimeters, so SI 20 ES has a 20 mm bore.
- Where are SI ES rod end bearings used?
- They are common in hydraulic cylinders, steering systems, suspensions and oscillating mechanisms. Agricultural and road machinery, lifting equipment and similar applications rely on them to compensate for misalignment and angular movement.
- How do I request a quote for an SI ES bearing?
- Send the full code via WhatsApp or email to MR Industrial Accessories. We will quote the SI ES series and help you confirm the size and thread type your equipment requires.
