How to Determine the Quality of a Single Row Ball Slewing Bearing?

Single row ball slewing bearing is an important component of the machinery. Essentially, every machine ends up having this part, and since the components are more fragile, it can be considered as a consumable. We need to purchase it frequently to maintain the normal operation of the machine.

Discrimination method for the quality of single row ball slewing bearing

Determine the quality of single row ball slewing bearing by brand

In this regard, we can start with the brand of single row ball slewing bearing. If the machine itself is a product of a well-known brand, it is best to purchase parts of the same brand. Why? Because each brand uses different alloy formulas, there are subtle differences. When the brand eliminates products, the natural compatibility is the highest.

Determine the quality of single row ball slewing bearing by toughness

Secondly, when we purchase the single row ball slewing bearing. Pay attention to the toughness of the product. Because the parts are thin, many parts look good but receive compensation after being placed on the machine for a long time. In choosing, in fact, you can buy more brands in practice.

Determine the quality of a single row ball slewing bearing during use

We usually use it during this time. What should be noted is that it is the running state that protects the machine. You can add some protective oil from time to time to effectively extend its service life.

The single row ball slewing bearing is mainly composed of upper and lower rings and a ball filling. The overall design of the single row ball slewing bearing is a low-speed, light load rotation solution. There are two designs of single row and double-row, and the convenience of pre-drilled mounting holes.

Single row ball slewing bearings are representatives of rolling bearings. It has a wide range of applications, is suitable for high-speed or even high-speed operation, and is very durable. This type of bearing has low friction, high limit speed, simple structure, low cost, and is easy to achieve high manufacturing accuracy.

Single row ball slewing bearings have a certain degree of aligning ability

Relative to the bearing seat hole tilted 10 degrees, it can still work， but it has a certain impact on the life of the bearing. The cage of the single row ball slewing bearing is a wave-shaped cage stamped from steel plate, while the metal cage is mainly used for large bearings. The seal of the single row ball slewing bearing is on the one hand to prevent grease leakage and filling, and on the other hand, to prevent dust, impurities, and moisture from entering the bearing and affecting normal operation.

Since the single row ball slewing bearing mainly works in heavy-duty and low-speed conditions, the seal ring has two structures: rubber ring and labyrinth ring. The rubber seal itself has a simple structure. The advantages of small space usage and reliable sealing have been widely used, but its disadvantage is that the rubber seal lip is easy to age prematurely under high-temperature conditions and loses sealing performance, so the working conditions under high-temperature conditions are single.
