Correct selection of FAG bearings are bearings function into full play in protection. If poorly conceived in the mechanical design, load overload can occur, leading to fragmentation, rolling road rolling flake or crack. Meet the problem of carrying capacity is a primary consideration, internal design are the key factors, proper material selection and heat treatment of materials is also important. According to the actual conditions of the host, should generally be given to spatial location, rotation, rotation speed, load size and nature areas such as precision, friction torque, and how it was installed. In addition, the bearing clearance are also factors that cannot be ignored.
In General, engineering machinery, mining machinery and crane applications, typically should choose a large clearance of FAG bearings. If the clearance is too small, bearing fixed because of poor support flatness would lead to reduced bearing clearance. The bearing in operation there was a blockage or rolling crush appears sound and raceways caused partial failure resulting from excessive stress.
The other hand, due to the flatness of seating makes the fixed bearing appears after "waves", keeping the rolling elements are not on the same plane, the resulting friction torque is too great.
Based on experience, General slewing bearing clearance shall be not less than 1.2 times of mounting surface flatness.
