SKF rod ends of the SIA ES-2RS series are radial spherical plain bearings with double sealing. They are used to transmit radial loads and allow angular misalignment in mechanisms that oscillate or rotate slowly. Their design with a spherical plain bearing and split housing facilitates mounting and absorbs alignment errors between shafts. MR Accesorios Industriales sells this line as an official brand for the Argentine industrial market.

The designation SIA identifies a radial rod end with a split housing and spherical plain bearing. The number that follows indicates the bore diameter in millimeters: for example, SIA 40 ES-2RS corresponds to a 40 mm bore. The suffix ES indicates that the rod end has a groove and lubrication holes, which allows relubrication. The suffix 2RS indicates double elastomer sealing, one on each side, to retain lubricant and block contaminants. Thus, the series covers sizes from 40 to 70 mm in the available examples.

These rod ends are used in agricultural machinery, earthmoving equipment, presses, conveyors, cranes and hydraulic systems. In Argentine industry they appear in seeders, harvesters, trailers and road equipment, where vibrations and variable loads demand robust articulations. They are also used in industrial doors and gates, robot arms and steering mechanisms. Their ability to oscillate without failure makes them suitable for pivot points that are not perfectly aligned.

To select a rod end, verify the bore diameter, the type of load (radial, axial or combined) and the required misalignment angle. The 2RS sealing is convenient in dusty or humid environments; if the equipment operates clean and at high frequency, an unsealed version can be evaluated. During mounting, ensure the housing is clean and free of burrs, and that the rod end seats correctly. Periodic lubrication with lithium grease is important when the ES groove is present. Initial alignment prevents lateral stresses.

SKF rod ends of this series are interchangeable with equivalent products from other brands that follow the same dimensional and functional designation. When replacing, compare the bore diameter, the inner ring width, the thread (if any) and the type of sealing. Not all brands maintain the same tolerances or the same radial clearance. If in doubt, consult the supplier and verify that the new rod end meets the load and misalignment requirements of the equipment.

To request a quote, send the complete part number of the rod end you need via WhatsApp to MR Accesorios Industriales. If you don't have it at hand, indicate the bore dimensions and the type of sealing. The technical team helps you identify the correct reference and verify interchangeability with the original part. MR sells SKF as an official brand, backed by more than 80 years in the industrial field.
