SKF SIQG ES series radial spherical plain bearings are spherical joints that allow oscillating movements and angular misalignment in industrial machinery. They are used in hydraulic cylinders, steering systems, suspension and mechanisms where smooth rotation with radial load is required. MR Accesorios Industriales carries this line as a brand, with technical advice to choose the right size according to the housing and the type of load.

The SIQG … ES designation reads as follows: SIQG identifies the series of radial spherical plain bearings with inner thread and steel cage, while ES indicates that they have elastomer seals on both sides. The central number, which in the examples ranges from 16 to 80, corresponds to the bore diameter of the inner ring. Thus, a SIQG 25 ES has a 25 mm bore and double sealing. The larger that number, the greater the load capacity of the rod end bearing.

These rod end bearings are used in hydraulic and pneumatic cylinders, steering arms, industrial vehicle suspension, road machinery, agricultural equipment and oscillating motion transmission systems. In Argentina you will find them in combine harvesters, cranes, presses, conveyors and earthmoving equipment. Their sealed design makes them suitable for environments with dust, mud or water, where an unsealed joint would wear quickly.

To select an SIQG ES, take into account the bore diameter, the inner ring width, the radial load and the permissible misalignment angle. The ES seal comes from the factory and requires no additional maintenance, but it is advisable to check that the housing has the proper chamfer so as not to damage the seal. During assembly, align the shafts and avoid striking the rod end bearing; use suitable assembly tools. The initial lubrication comes from the factory and in service it can be relubricated if the design allows it.

As for equivalences, SKF SIQG ES rod end bearings are interchangeable with other brands that follow the same dimensional designation, such as the GE..ES series or similar. Always verify tolerances and the type of sealing before replacing. If you have doubts, send us the full part number of the rod end bearing you need and we will confirm the equivalence with our experience.
