Product Description
SB75A Radial Spherical Plain Bearing 75x120x64mm Grease Nipple Type Heavy Load For Hydraulic Cylinders
Product Overview
- 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 specifiions. 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 lubriion 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.

FAQ
Q1: What are the exact dimensions of SB75A bearing?
A: Inner bore 75mm, outer diameter 120mm, outer ring width 64mm, inner ring width 55mm.
Q2: What is the difference between SB75A and ordinary SB75?
A: SB75A has grease fitting for refilling lubricant; basic SB75 is non-relubriable maintenance-free type without oil hole.
Q3: Can this bearing run at high continuous rotating speed?
A: Mainly designed for swing/oscillating motion, not suitable for long-time high-speed rotation.
Q4: Can it bear radial and axial loads simultaneously?
A: Primarily bears radial loads, can withstand moderate bidirectional axial loads.
Q5: Is this bearing interchangeable with GE75ES?
A: Same installation dimensions, can be mutually replaced for general industrial use.
Q6: Why no sealing gaskets on both sides?
A: Reserved gap for lubricant circulation, convenient grease replenishment, suited for indoor dusty-free heavy load working environments.
