SKF SIR40ES Bearing

SKF SIR 40 ES is a maintenance‑required rod end bearing with a spherical plain bearing insert that accepts a 40 mm bore and a female M35 x 1.5 thread, designed for pivot joints and linkages where misalignment must be accommodated. The housing is steel, with inner and outer rings made from bearing steel and a steel/steel sliding contact surface, and it is specified without an external seal. It carries a dynamic load rating of 100 kN and a static rating of 200 kN, reflecting robust performance for mid‑range pivot joints in machinery. The rod end uses a female thread with clamping screws to secure it to a mating shank, and relubrication is required via a grease fitting in the housing, enabling maintenance over the service life. Sealing variants are not indicated for this model.
