SKF SI..ES-2RS rod ends and spherical bearings are radial rod ends with a male threaded shank and two-sided sealing. They are used to transmit oscillating movements and radial loads in mechanisms that require angular alignment. Their spherical rod end design compensates for misalignment and works with shafts that are not perfectly aligned. They are suitable for industrial applications where articulation and resistance to contamination are required.

The designation SI … ES-2RS is interpreted as follows: SI indicates a radial rod end with male shank; the number that follows is the nominal diameter of the rod end bore in millimeters (for example, SI 30 ES-2RS has a 30 mm bore diameter). The suffix ES identifies the design with a steel spherical rod end and two-piece cage; 2RS indicates double-lip sealing on both sides, which retains the lubricant and blocks the entry of dust and moisture. This combination is common in the SKF SI..ES-2RS series.

These rod ends are used in sectors such as agriculture, the metallurgical industry, material handling and automotive. In Argentina, they appear in steering arms, hydraulic cylinders, chain tensioners, suspension systems, road machinery and earthmoving equipment. Their ability to withstand radial loads and oscillations makes them useful in agricultural machinery linkages, such as seeders and harvesters, and in industrial equipment where freedom of movement with variable alignment is required.

To select an SI..ES-2RS rod end, take into account the bore diameter, the thread type (male or female) and the load direction. The 2RS sealing is suitable for environments with moderate dust or moisture; if there is exposure to liquids or abrasive dirt, consider additional protection. Installation must ensure that the shank is perpendicular to the oscillation axis and that the rod end has angular freedom. Lubrication is permanent in the sealed versions, but relubrication may be required in severe applications. Check the alignment to avoid lateral stresses.

SKF SI..ES-2RS series rod ends are interchangeable with equivalent products from other brands that follow the same dimensional designation. When requesting a quote, it is important to provide the complete part number and the working conditions to ensure compatibility. At MR Accesorios Industriales we sell SKF as an official brand and can advise you on equivalence with other series. Not all rod ends with the same diameter have the same load capacity; therefore, always confirm the exact part number before replacing.
