SKF SI ES series rod end bearings are radial spherical plain bearings with a female thread, designed to withstand radial loads and oscillating and misalignment movements. They are used in mechanisms that require angular freedom, such as hydraulic cylinders, steering systems and transmission systems. MR Accesorios Industriales carries this line as an official brand, with technical advice to choose the right size for your application.

The SI … ES designation reads as follows: SI indicates a rod end bearing with a female thread, # is the nominal bore diameter in millimeters, and ES indicates the design with a steel cage and standard lubrication. For example, SI 15 ES has a 15 mm bore diameter; SI 20 ES, 20 mm; and so on. This nomenclature lets you quickly identify the size and mounting type: the female thread makes it easy to fasten with a threaded rod or pin.

These bearings are used in industries such as metalworking, automotive, agricultural and construction. In Argentina they are commonly found in hydraulic cylinders of road machinery, in vehicle steering systems, in suspension arms and in oscillating motion equipment. They are also used in sliding doors, actuators and lifting mechanisms where misalignments and repetitive angular movements need to be compensated for.

To select the right bearing, take into account the bore diameter, the thread type (female or male) and the load conditions. The SI ES series can be lubricated and is designed to work with a steel cage. During mounting, ensure correct alignment and avoid pure axial loads. If the environment has dust or moisture, consider additional seals. Periodic lubrication extends service life, especially in applications with continuous motion.

As for equivalents, rod end bearings are manufactured under international standards that allow dimensions to be interchanged between different brands. Although codes may vary, a bearing with the same dimensions and thread type is usually compatible. Always verify tolerances and radial clearance before replacing. MR Accesorios Industriales can advise you on interchangeability without compromising equipment performance.
