Description
SKF SIJ 40 ES is a spherical plain bearing reference, within Bearings. Request a quote for SIJ 40 ES via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The SKF rod end bearings of the SIJ ES series are radial spherical plain bearings with internal thread, designed to withstand radial loads and oscillating movements on shafts that require alignment. They are used in hydraulic cylinders, steering systems and articulation mechanisms. At MR Accesorios Industriales we carry them as an official brand and advise you so that you choose the correct part number for your application.
The SIJ designation corresponds to a radial spherical plain bearing with internal thread, while the ES suffix indicates that it incorporates a PTFE insert and a stainless steel cage, which reduces maintenance and improves corrosion resistance. The numbers that appear in the examples, such as SIJ 25 ES or SIJ 40 ES, indicate the bore diameter in millimeters. Thus, the series ranges from compact sizes to larger sizes for different load capacities.
These bearings are used in industries such as metallurgy, automotive, agriculture and construction. In Argentina it is common to find them in hydraulic cylinders of road machinery, in steering systems of heavy vehicles, in robot arms and in earthmoving equipment. Their design allows them to absorb angular misalignments and radial loads, which makes them ideal for articulation points where the shaft is not perfectly aligned.
To select the right bearing, take into account the bore diameter, the type of load (radial, axial or combined) and the environmental conditions. Sealing and lubrication are key: the ES version already includes a self-lubricating insert, but in dusty or humid environments it may require additional seals. During mounting, ensure correct alignment and avoid striking the spherical plain bearing. The internal thread facilitates fastening with screws or pins.
As for equivalents, other brands offer rod end bearings with similar designations, but the dimensions and capacities may vary. Always verify the complete part number and the tolerances before replacing a component. Interchangeability between brands is not guaranteed by diameter alone; factors such as width, thread type and insert material influence performance.

Frequently Asked Questions
- What does the ES suffix mean in SIJ bearings?
- The ES suffix indicates that the bearing incorporates a PTFE insert and a stainless steel cage. This gives it self-lubricating properties and greater corrosion resistance, ideal for applications where maintenance is limited.
- How do I choose the correct size of rod end bearing?
- You must consider the bore diameter, the type of load and the working conditions. Part numbers such as SIJ 25 ES, SIJ 30 ES, etc., indicate the diameter in millimeters. Consult us with your shaft measurements and we will advise you.
- Are SKF SIJ ES bearings interchangeable with other brands?
- Not always. Although they may share main dimensions, the width, thread type or insert material may vary. Always verify the complete part number and the technical specifications before replacing.
