Slewing defects

 In fact, construction machinery parts in the process must be very careful and attentive, if a little defect can cause health

Produced parts can not be used. lysn-bearing fact, there is little problem will cause the entire part of the damage, so the rotary support

Order there will be a lot of defects, and these defects can affect the use of parts in the construction.
Slewing defects are:
1, there was a clear crystal surface, the reason is because the processing as long as a result of overheating, will reduce the toughness of parts

And impact resistance.
2, the shaft has significant deformation, deformation and mechanical parts even buy back the tab on the mouth was not gentle, will also affect the machine

Mechanical safety at work.
3, the surface has obvious cracks, due to the impact of slewing ring bearing capacity.
4, the surface cause surface decarburization problems of wear resistance and fatigue strength in serious decline.
So when you buy slewing ring must be carefully checked to see if there is no such product defects, if there is

Suggest that you do not buy. Even if there are defects in very cheap to buy back, the mechanical work and life will be greatly reduced fold

Buckle.
