The basic structure of wheel bearings

Wheel bearings can withstand a large axial load, radial load and overturning moment, such as integrated load, set bearing, large bearing rotation, transmission, fixed and other functions in a special structure. A series of four point contact ball bearing turntable bearing turntable belonging, which consists of two races composition, compact, ball and arc raceway four-point contact. Mainly used truck cranes, tower cranes, excavators, piling machines, construction vehicles, radar scanning equipment to withstand the overturning moment and vertical axial force, the level of tendency force of machinery.

Rolling tower crane repair Points to note

Most tower crane used in the rolling bearing should be renewed in the repair and overhaul period. Rolling bearing secondary site without carefully checked found to be defective may continue to be used. Where the ball and spacer ring rust, raceway surface wear and fatigue erosion, balls and steel columns for wear scratches, damage and isolation ring inside, coat cracked bearings, it must be replaced. The inspection can continue to use the rolling bearing must be clean, in order to continue to use.

Cranes bearing applications

Lifting or horizontal applications, bearing play a significant role in regulating the different lifting equipment, bearing requirements are not the same. Here a crane bearing, pulley in the crane hook with that there is a bearing, full complement cylindrical roller bearings, with seals on both sides, using rope or crane hook bearing movement of goods known as mobile cranes bearing.
