  • Heavy Duty Slewing Bearing For Port Crane Equipment

    Port hoisting machinery generally includes portal cranes, ship unloaders, floating cranes, etc., commonly used single-row four-point ball type, three-row roller type and double-row ball type slewing ring bearings. Port cranes usually use three-row roller slewing bearings with internal or external teeth with a diameter of 4 meters to withstand high overturning moments. Our company often provides slewing bearings in this field, such as single-row ball type, 011/012.60.2000, 011/012.60.2240, 011/012.60.2500, 011/012.60.2800, 011/012.60.3150, etc., three-row roller type, etc. Slewing bearings include 131/132.45.2500, 131/132.45.2800, 131/132.50.3150, 131/132.50.3550, 131/132.50.4000, 131/132.50.4500, etc., as well as double-row ball slewing bearings 021/022.50 .2500, 021/022.50.2800, etc., are our main advantage products. If non-standard customization is required, our company can provide technical support such as selection, design, calculation, etc., you can call for details.

  • RB Series Crossed Roller Bearing

    Crossed roller bearings are lightweight, compact bearings with thinnest possible inner and outer rings with high rigidity, because of its vertical arrangement of cylindrical rollers with a 90°V groove through the separate spacers in the deep groove rolling surface. This special design allows just one bearing to carry loads in all directions including radial, axial and moment loads. RB standard type is a bearing with thinnest possible inner and outer rings because the outer ring is split while the inner ring is integrated into the main body. The miniaturized design of thin-walled size is helpful for the light and thin design of related structures. The overall structure of the inner ring is more suitable for occasions with high rotation accuracy of the inner ring, and the stable rotation accuracy reaches microns; it is suitable for precision testing instruments, robot joints, and direct drive torque. Motors, high-precision turntables and other applications requiring high precision and high rigidity.
