GQZ SL07056 Double Row Full Complement Cylindrical Roller Bearing 280×420×155mm Heavy Shock Load Design

SL07056 is double row full complement cylindrical roller bearing without cage. It adopts maximum quantity rollers arrangement to achieve ultra-high radial load capacity. Semi-locating structure can bear radial load and moderate bidirectional axial loads. Suitable for low-speed, heavy shock working environments. Open design supports regular re-lubrication maintenance. Widely applied on heavy lifting machinery, mining equipment, steel mill transmission assemblies, crane sheaves and low-speed heavy rotary equipment.
