OEM 50mm to 9000mm Slewing Ring Bearing OEM

Slewing bearings are widely used in various types of machinery and equipment. At present, there are many brands of slewing bearings on the market, and the quality is also different. So, how to choose a slewing bearing? What should I pay attention to when buying a slewing bearing? In order to select the slewing bearing products of qualified quality.

When purchasing slewing ring bearings, there are many issues that need to be paid attention to, such as load, strength of bolts, and whether there are uniform bolt holes.

Is the distribution of slewing ring bearing load reasonable?

Bearings are mounted on a lack of a uniform support surface, and a common mistake during the design phase of the support structure is that the slewing ring assumes that the support structure is sufficiently rigid. However, local deformation can change the load, causing the bearing to have different load magnitudes. Failure to take proper steps can easily lead to slewing ring bearing failure.

Is the slewing ring bearing bolt strong enough?

Be sure to choose the right slewing ring bearing product for your installation. This stage is often overlooked, leading to the possibility of system failure. Typically, equipment designers are responsible for determining the correct type of fasteners required for the project.

However, fastener suppliers and manufacturers should really get a measure of what a given fastener can withstand. They will be able to assist in the calculation of the bolt loads to confirm the integrity of the fasteners.

Is there a unified slewing ring bearing bolt hole design?

Fasteners need to be placed in more places in larger load areas. Bolt holes can be used as hazardous support structures only in areas where large loads occur and should therefore not be ignored in the overall design of the product.

It is important to remember that there is a lot of exercise load, not just the mounting part. Uniform bolt circles can help reduce bending and load distribution in bearings, fasteners, and support structures.

In addition, when we buy a slewing ring bearing, we should also pay attention to the toughness of this product, because this part is very thin, so many parts look good, but it will be reimbursed after using it in the machine for a long time. When choosing, you can actually buy a few more brands and practice them in practice.

When purchasing slewing bearing products, be sure to look at the brand words and labels printed on the slewing bearing. Most of the products produced by the factory use steel stamping technology, the fonts are very small, and they are embossed before heat treatment, so although the fonts are small, they are deeply concave and very clear.

The fonts of counterfeit products are relatively vague. Due to the rough printing technology, the fonts float on the surface, and some can even be easily erased by hand.

2.The slewing ring bearing application

1. Lifting machinery

Lifting machinery includes truck cranes, tower cranes and trailers, etc. Due to the harsh environment of these machines, the rotating parts are often subject to great impact, so these parts will use customized slewing bearings.

For example, to provide the LYMC bearing manufacturer with the size and operating environment required by the machine, the manufacturer will arrange the engineer to design the suitable bearing according to the actual situation, and then put it into use, which can not only meet the needs of the lifting machinery, but also prolong the service life. Huge improvements.

2.Construction machinery

The simple division of construction machinery is like excavators, loaders, etc. The slewing bearing can bear axial force, radial force and overturning force at the same time, and the structure is very compact. It needs to be rotated continuously during the operation of the excavator. The slewing bearing is the core component of the rotation. The application of construction machinery belongs to the basic application of slewing bearing, and it is also widely used.

3. Processing machinery

Processing machinery like material processing, food processing, metallurgy and so on. With the continuous development of science and technology, people are no longer satisfied with the application of slewing bearings only in construction machinery, and turn their attention to equipment platform processing machinery. Because the slewing bearing is more compact than the original bearing, the external force can also be larger, and the performance and structure are better, so it is also widely used in processing machinery.

4. Military equipment

The current military competition is about the hard power of military equipment. As we saw on TV, the tank turns the cannon head, and a shell hits the target accurately. In this link, the slewing bearing plays a very good supporting role;

There are also anti-aircraft guns, radars, rocket launch pads, etc., a very important structure in the timely rotation, jump and stable launch of military equipment is the turntable bearing, which has better performance than traditional bearings.

5. Medical machinery

In many large-scale medical equipment, in order to take care of the patient’s physical condition, it is necessary to rotate the equipment in time to adapt to the patient’s body. At this time, the equipment is required not only to have high accuracy, but also to have low noise.

These rotations require slewing bearings. help. The high-accuracy, low-noise, long-life, and high-reliability series of medical equipment spindle rotary bearings developed now have been widely used in large medical equipment such as gamma knives, CT machines, and nuclear magnetic resonance machines.

6. Others

In addition to its applications in industry and medical care, slewing bearings have its shadow in the field of power generation and life. The yaw bearing of wind turbines is installed at the connection between the tower and the cockpit, and the pitch bearing is installed at the root of each blade. connection with the wheel hub.

Each wind turbine uses one set of yaw bearing and three sets of pitch bearing. Through the application of slewing bearing on wind power generation equipment, the process of generating electricity can be effectively changed by the difference of wind power.

In the whole process, the part where the root of the blade is connected with it is the concrete embodiment of the slewing bearing. The main applications of slewing bearings in life are concentrated in playgrounds, such as Ferris wheels, roller coasters, pendulum clocks and merry-go-rounds, etc. The effective application of slewing ring bearings has ensured the safety of life.
