GE 15 ES 2RS is a radial spherical plain bearing — meaning the inner ring has a spherical (convex) outer surface and the outer ring a matching concave surface. This lets it self-align, accommodating shaft misalignment, tilting or oscillating motion between the shaft and housing.
-
Its construction uses steel-on-steel sliding surfaces (inner and outer rings from high-carbon chromium bearing steel), giving high load capacity, good wear resistance, and strong performance under heavy, static, shock or alternating loads.
-
The “2RS” designation indicates the bearing has double-lip rubber seals on both sides, helping prevent dust, dirt, and moisture ingress — useful in dirty or humid environments — while protecting internal surfaces.
-
It also includes lubrication provisions (lubrication groove and holes), allowing relubrication to maintain smooth operation and prolong service life under load or oscillating motion.
-
GE 15 ES 2RS is built for heavy-duty applications where self-alignment, durability, and load-bearing capacity matter more than high–speed rotation — for example in hydraulic cylinders, heavy machinery linkages, suspension or pivot joints, and industrial equipment where movement or misalignment occurs.
