SB75A Radial Spherical Plain Bearing 75x120x64mm Grease Nipple Type Heavy Load For Hydraulic Cylinders

• SB75A is a heavy-duty radial spherical plain bearing with built-in grease nipple, standard overall dimension 75×120×64 mm, compliant with IKO international specifications. It is precision manufactured from high-strength GCr15 chrome bearing steel, composed of inner spherical ring and outer concave ring paired together.The spherical contact surface enables the bearing to accommodate angular misalignment between shaft and housing automatically. Equipped with lubrication hole for regular grease refilling, it greatly extends service life under heavy alternating loads. Open structure is designed for oil/grease circulation, widely used for swing, oscillating and low-speed rotary joints across all heavy industrial fields.
