Why do we need turntable bearing?

The turntable bearing is widely used in the real industry and is called "the joint of the machine". Necessary important transmission parts. With the rapid development of the machinery industry, turntable bearings have been widely used in marine equipment, construction machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.

What does the light series turntable bearing include?

The light turntable bearing has the same structural form as the ordinary turntable bearing, with light weight and flexible rotation. Widely used in food machinery, filling machinery, environmental protection machinery and other fields.

1. HS series

Single row four-point contact ball turntable bearing

The single-row four-point contact ball turntable bearing is composed of two races, with a compact structure, and the steel ball contacts the arc raceway at four points. Mainly used in truck cranes, tower cranes, excavators, pile drivers, engineering vehicles, radar scanning equipment and other machines that are subjected to overturning moment, vertical axial force, and horizontal inclination force.

2. HJ series

Single row cross roller turntable bearing

The single-row cross-roller turntable bearing consists of two races, with compact structure, high manufacturing accuracy, small assembly clearance, and high requirements for installation accuracy. Overturning moment and large radial force are widely used in transportation, construction machinery and military products.

What is the purpose of the turntable bearing?

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

The friction of the turntable bearing is not enough, and lubrication is also required. Otherwise, it will be used for a long time and the friction force will be too large, which will affect the normal operation of the parts. Therefore, after using the turntable bearing for a period of time, it is very important to carry out proper maintenance. You can brush some lubricating oil, which can ensure that it can still work normally in a suitable environment.

How to install the turntable bearing correctly?

After cleaning the outer surface of the bearing before the turntable bearing is installed, please pay attention to cleaning the sand of the casting and the bearing parts with burrs and acute angles, so as to avoid residual sand and metal debris during installation inside the bearing, which will affect the assembly quality. Disassembly of tapered bore bearings is always fitted with excess fit. The excess depends on the length of the thrust distance between the bearing and the tapered journal or sleeve. Under the action of thrust, the radial clearance of the bearing decreases, and the size of the thrust determines the fit. During the installation process, the radial clearance of the bearing can be continuously measured until the required radial clearance and ideal pressure matching are achieved.

The choice for turntable bearing is currently the choice of more and more people. LYXQL Slewing Bearing Co., Ltd. strives to offer high quality products at reasonable prices, efficient production times and the most professional customer service.
