SKF SA ES rod end bearings are radial spherical plain bearings with a male thread, designed to withstand radial loads and transmit oscillating or aligning motion. They are used in mechanisms that require angular freedom, such as hydraulic cylinders, steering systems and suspension systems. MR Accesorios Industriales carries this SKF line, an official brand that MR sells, with technical advice to choose the right size for your application.

The SA ES designation reads as follows: SA indicates a radial rod end bearing with a male threaded shank; ES indicates that it incorporates a hardened steel insert and a cage made of anti-friction material, with pre-applied lubrication. Examples SA 15 ES, SA 17 ES, SA 20 ES, SA 25 ES and SA 30 ES show the nominal bore diameter in millimeters (15, 17, 20, 25 and 30). The ES suffix does not vary; it always indicates the same type of internal construction.

In Argentine industry, these rod end bearings appear in hydraulic and pneumatic cylinders, steering arms, agricultural machinery suspension, earthmoving equipment and transmission systems with oscillating shafts. They are also found in automatic doors, cranes and lifting equipment. Their ability to self-align prevents bending stresses on the shanks and simplifies assembly when misalignments are unavoidable.

To select an SA ES, take into account the bore diameter, the thread type (male or female) and the radial load it will withstand. The rod end bearing's sealing protects against dust and moisture; if the environment is aggressive, consider adding seals or boots. Lubrication is permanent in most cases, but demanding applications may require re-greasing. Alignment between the shank and the support must respect the permissible oscillation angle to avoid damaging the insert.

SKF SA ES rod end bearings are interchangeable with those of other brands that follow the same dimensional designation, such as equivalent series from European or Asian manufacturers. Always verify the bore diameter, thread pitch and inner ring width before replacing. At MR Accesorios Industriales we can guide you on compatibility and alternatives for your equipment.
