SB‑110A Radial Spherical Plain Bearing 110*170*93mm Excavator Hydraulic Cylinder Construction Machinery Pivot Joint

• SB‑110A is an open‑style oil‑suppliable radial spherical plain bearing with one‑split outer‑ring structure. Its steel‑on‑steel sliding surface bears heavy radial load and shock load. It permits 5‑degree shaft angular deviation to compensate installation misalignment. The lubrication holes support periodic grease replenishment, well‑suited for excavator hinge points, hydraulic cylinders and heavy‑duty construction‑machinery pivoting assemblies.
