How to choose slewing bearings

As a kind of more precise mechanical parts, slewing bearings are widely used in many large-scale equipment. In order to ensure the good performance of slewing bearings, we need to pay special attention when selecting materials. Let's take a look at what details should be paid attention to when choosing slewing bearings?
First of all, it depends on whether the outer packaging is clear. Generally, regular manufacturers have extremely strict requirements for outer packaging and will not be confused. Therefore, regular brands have specialized designers to design the outer packaging specifically, and will also choose better production conditions. The factory produces production, so both the quality and appearance are very clear.
At the same time, look at whether the steel stamp is clear, because there will be brand words, labels, etc. on the surface of the turntable bearing. Although the font is small, the regular manufacturers use steel stamp skills, and the concave deepness is naturally very clear.
To check if there is a noise, first grasp the inner sleeve of the turntable bearing with your left hand, and turn the cover with your right hand to make it rotate, and listen to whether there is a noise. Under normal circumstances, due to the backward production conditions of counterfeit products, in the actual production process, it is likely that impurities such as sand will be mixed in the turntable bearing body, and noise will inevitably be produced when rotating.
Then whether the chamfer of the slewing bearing is uniform, the chamfering of the slewing bearing is also the junction of the horizontal plane and the vertical plane. Need to check whether the texture here is smooth, because the counterfeit slewing bearing will be produced in a relatively poor environment, so the processing of many corner details is unsatisfactory.
The above are some details that need to be paid attention to when choosing slewing bearings. Consumers should pay more attention when choosing slewing bearings to ensure the quality of slewing bearings.
