Spherical plain bearings and rod ends

A spherical plain bearing or rod end is a plain bearing: the inner ring is spherical and slides against the outer ring, without rolling elements. It is designed for oscillating movements and to absorb angular misalignment, not for continuous rotation at high speed. It is selected based on the type of load (radial, axial, or combined), the type of movement, the working environment, and the mounting method.

The series are identified by letters and the number is the bore diameter in millimeters. In GAC 25 F, GAC 100 F, or GAC 120 F, GAC is the series of angular contact spherical plain bearings, which take radial and axial load in one direction, and the 25, 100, or 120 is the bore in mm. The variant GAC 25 SA is another execution of the same size. There are also radial and axial spherical plain bearings, with different mounting and sealing methods.

Depending on the material pair, the need for relubrication changes: steel-on-steel bearings are lubricated periodically and others work with a self-lubricating material. Typical applications are hydraulic and pneumatic cylinders, steering and suspensions, reciprocating machines, construction equipment, agricultural and lifting equipment, where the spherical plain bearing accommodates misalignment without generating stress on the shaft.

In this subcategory we work with SKF. To request a quote, send us the complete code, or the bore diameter, outside diameter, width, and type of load via WhatsApp or email. If you have the equivalent from another brand or a drawing, include that too: we will indicate the corresponding spherical plain bearing and respond promptly.
