What do you know about the slewing bearing?

The slewing bearing is a new type of mechanical parts consisting of inner and outer rings, rolling elements, etc. is. The slewing bearing is a large bearing that can bear comprehensive loads and can accommodate large axial and radial loads and tilting moments equal time.

Which product series has slewing bearings?

1. Single row four-point contact ball slewing bearing

Single row four-point contact slewing bearing consists of two racerings with compact structure, light weight, four-point contact between the steel ball and the arc raceway, and can absorb axial forces, radial forces and tilting moments equal time. Construction machinery such as rotary conveyor, welding manipulator, small and medium crane and excavator can be selected.

2. Double row reducer slewing bearing

The double row slewing bearing has three raceways, and the steel balls and spacers can be discharged directly into the upper and lower raceways. Depending on the load, two rows of steel balls with different diameters are arranged. This type of open mounting is very practical, and the bearing angle of the upper and lower arch raceways is 90°, which allows a large axial force and a large tilting moment to be absorbed. If the radial force is greater than 0.1x the axial force, the raceway must be specially designed. The axial and radial dimensions of the double row reducer ball slewing ring are relatively large and the structure is narrow, it is particularly suitable for loading and unloading machinery such as tower cranes and truck cranes that require medium or larger diameters.

What is the purpose of the slewing bearing?

Its purpose is to carry heavier and larger objects, and its own centripetal force is high, which is determined by its working principle. Therefore, he needs a steel material that can guarantee the quality of the material.

The friction of the slewing bearing is not sufficient and lubrication is also required. Otherwise, it will be used for a long time and the frictional force is too large, which will affect the normal operation of the parts. Therefore, it is very important to carry out proper maintenance after prolonged use of the slewing bearing. You can apply some lubricating oil to ensure that it continues to function normally in a suitable environment.

What are the precautions for the detection of slewing bearings?

Due to the different position of the meter, which is fixed by different people, the measured value changes. Therefore, the accuracy of the data is ensured by repeatedly measuring and recording!

I also remind the owners that the slewing bearing clearance also has a default value. If the game is held at 0.5-3mm, it is normal. If it is exceeded, it means that everyone must check whether it needs to be repaired or replaced!
