Rod ends in the SKF SIA ES-2RS line are radial spherical plain bearings that feature double sealing. They handle radial loads while permitting angular misalignment in linkages that pivot or turn slowly. A spherical plain bearing inside a split housing simplifies installation and compensates for shaft misalignment. MR Industrial Accessories supplies this line to industrial buyers in the United States and several Latin American countries.

In the part number, SIA denotes a radial rod end with a split housing and a spherical plain bearing. The digits that come next give the bore size in millimeters; for instance, SIA 40 ES-2RS has a 40 mm bore. The letters ES show that a groove and lubrication holes are present, so the joint can be relubricated. The 2RS suffix means there are two elastomer seals, one per side, to keep lubricant in and contaminants out. Available examples in this series range from 40 to 70 mm.

Typical applications include agricultural equipment, earthmoving machines, presses, conveyors, cranes and hydraulic circuits. In industrial plants, these rod ends appear on seeders, harvesters, trailers and road maintenance equipment, where vibration and changing loads call for sturdy pivot joints. They also serve in industrial doors and gates, robotic arms and steering linkages. Because they can oscillate without binding, they suit pivot points that are not perfectly aligned.

When choosing a rod end, check the bore diameter, the load type (radial, axial or combined) and the misalignment angle required. The 2RS seals are a good fit for dusty or damp conditions; in clean, high-frequency operation, an open version might be considered. During installation, keep the housing clean and free of burrs, and make sure the rod end seats properly. If the ES groove is present, schedule regular lubrication with lithium grease. Aligning the parts at the start avoids side loads.

These SKF rod ends can be replaced by equivalent products from other manufacturers that use the same dimensional and functional designation. For a replacement, compare the bore diameter, inner ring width, thread (if applicable) and sealing type. Tolerances and radial clearance can differ between brands. If anything is unclear, ask the supplier to confirm that the new rod end matches the load and misalignment needs of the equipment.
