SKF SIJ ES series rod end bearings are radial spherical plain bearings with an internal thread. They handle radial loads and oscillating motion where the shaft needs to align. Typical uses include hydraulic cylinders, steering linkages and articulation points. MR Industrial Accessories LLC supplies these bearings to customers across the United States, Canada, Mexico and South America and can help you confirm the right part number.
Reading the designation helps with selection. SIJ means a radial spherical plain bearing with internal thread. The ES suffix means the bearing has a PTFE insert and a stainless steel cage, which lowers maintenance needs and improves corrosion resistance. The number in the part number gives the bore diameter in millimeters, so SIJ 25 ES has a 25 mm bore and SIJ 40 ES has a 40 mm bore. The series covers compact sizes through larger sizes for different load capacities.
These bearings appear in metallurgy, automotive, agriculture and construction equipment. They are common in hydraulic cylinders on road machinery, steering systems on heavy vehicles, robot arms and earthmoving equipment. The design absorbs angular misalignment and radial loads, which suits articulation points where the shaft is not perfectly aligned.
When selecting a bearing, check the bore diameter, the load type (radial, axial or combined) and the working environment. Sealing and lubrication matter: the ES version has a self-lubricating insert, but dusty or humid conditions may call for extra seals. During mounting, keep the alignment correct and avoid striking the spherical plain bearing. The internal thread makes fastening with screws or pins straightforward.
Other brands offer rod end bearings with similar designations, but dimensions and capacities can differ. Verify the complete part number and tolerances before replacing a component. Diameter alone does not confirm interchangeability; width, thread type and insert material also affect performance.

Frequently asked questions
- What does the ES suffix mean in SIJ bearings?
- The ES suffix indicates a PTFE insert and a stainless steel cage. This provides self-lubricating properties and better corrosion resistance, which is useful where maintenance access is limited.
- How do I choose the correct size of rod end bearing?
- Consider the bore diameter, the load type and the working conditions. Part numbers such as SIJ 25 ES and SIJ 30 ES indicate the diameter in millimeters. Share your shaft measurements and the team can advise you.
- Are SKF SIJ ES bearings interchangeable with other brands?
- Not always. Even when main dimensions match, width, thread type or insert material may differ. Always check the complete part number and technical specifications before replacing a component.
