SKF SI E series radial rod ends are spherical bearings with a threaded shank that allow oscillating movements and angular misalignment. They are used in mechanisms that require smooth rotation and combined load capacity, such as hydraulic cylinders, steering systems and transmission systems. MR Accesorios Industriales sells this line so you can choose the right size for your application.

The SI E series designation reads as follows: SI indicates a radial rod end with a male shank, and E indicates a version with specific sealing features or design. The numbers in the examples, such as SI 6 E, SI 8 E, SI 10 E or SI 12 E, correspond to the nominal bore diameter, expressed in millimeters. The higher that number, the greater the load capacity and the overall dimensions of the rod end. To select the correct size, take into account the diameter of the shaft or pin that will house it.

These rod ends are used in industries in Argentina such as metalworking, automotive, agricultural and construction. They are found in hydraulic and pneumatic cylinders, steering arms, suspension systems, road machinery, lifting equipment and transmission mechanisms that require oscillating movements. They are also used in the food and packaging industry, where reliable, low-friction articulated movement is required.

To choose correctly, consider the radial and axial load it will bear, the required misalignment angle and the environmental conditions. The E-type sealing helps retain lubricant and protect against dust and moisture. During assembly, make sure the threaded shank is properly tightened and aligned with the movement of the mechanism. Periodic lubrication with suitable grease extends service life, especially in applications with alternating loads or moderate speeds.

As for equivalents and interchangeability, SKF SI E series rod ends can be replaced by products from other manufacturers that follow the same dimensional designation, such as similar series from INA, NSK or NTN. Always verify the critical dimensions: bore diameter, shank thread, width and tilt angle.
