swing bearing

Slewing ring bearing is widely used in excavator equipment. It belongs to wear parts. We are specialized in the production of engineering machinery slewing bearings, drive shafts and other gear parts. If you only need the bearing parts like steel balls, rollers, cages, it is also available. For some common model excavators’slewing bearing, we have ready stock and can deliver within one week. PC200, PC220, PC300 is our hot selling models and also the drive gear shaft. If you have old slewing bearing in hand, we can instruct you to measure the detailed size to make a professional drawing and then manufacture it for you.

Port hoisting machinery generally includes portal cranes, ship unloaders, floating cranes, etc., commonly used single-row four-point ball type, three-row roller type and double-row ball type slewing ring bearings. Port cranes usually use three-row roller slewing bearings with internal or external teeth with a diameter of 4 meters to withstand high overturning moments. Our company often provides slewing bearings in this field, such as single-row ball type, 011/012.60.2000, 011/012.60.2240, 011/012.60.2500, 011/012.60.2800, 011/012.60.3150, etc., three-row roller type, etc. Slewing bearings include 131/132.45.2500, 131/132.45.2800, 131/132.50.3150, 131/132.50.3550, 131/132.50.4000, 131/132.50.4500, etc., as well as double-row ball slewing bearings 021/022.50 .2500, 021/022.50.2800, etc., are our main advantage products. If non-standard customization is required, our company can provide technical support such as selection, design, calculation, etc., you can call for details.

Ladle turret is commonly known as continuous casting machine. Slewing bearing for ladle turret generally uses three row roller structure slewing bearing, such as 132.45.2500/2800/3150/3550, etc. This structural product is a slewing bearing with high bearing capacity. , mainly used in heavy duty work situations. It consists of three ferrules, the upper and lower rows of rollers are distributed horizontally, and the radial force is borne by the three rows of rollers arranged vertically, so it can withstand the axial force and tilting moment from two directions. The ladle turntable is the key equipment of the continuous casting machine. It is used to carry and support the ladle for pouring. It is usually set between the molten steel receiving span and the column row of the pouring span. The designed ladle rotation radius makes the ladle nozzle at the specified position above the tundish when pouring steel. The ladle is placed on the turntable by the crane on the side of the molten steel receiving span, and is rotated by the turntable to make the ladle stop above the tundish to supply its molten steel. The poured empty package is rotated through the turntable, and then transported back to the molten steel receiving span. The load-bearing capacity and safety performance of the product are required to be high, so the three-row roller structure slewing bearing is often used. If non-standard customization is required, our company can provide technical support such as selection, design, calculation, etc., you can call for details.

In amusement equipment, slewing bearings are used in Ferris wheels, large pendulums, and flying chairs. Broadly speaking, a slewing bearing is a large bearing that can withstand comprehensive loads, and can bear large axial, radial loads and overturning moments at the same time. Slewing bearings generally have mounting holes, internal gears or external gears, lubricating oil holes and sealing devices, so that the design of the main engine can be compact, easy to guide, and easy to maintain. Ferris wheel usually adopts double row ball slewing bearing. There are two rows of rolling elements, which can bear large axial load, radial load and tilting moment. It rotates flexibly and stably with higher safety factor. For some large ferris wheel, four contact ball slewing bearing is selected too, outer dia is about 4100mm, depth 85mm. Slewing ring bearings used on Ferris/Sky wheels are used with inner rings. In most cases, the bearing should be light enough and safe enough to rotate. The slewing ring bearings used on the Ferris wheel/sky wheel generally require a long service time, so it is also very important for anti-corrosion. If non-standard customization is required, our company can provide technical support such as selection, design, calculation, etc.

Slewing bearing is a new type of slewing product, which can bear large axial load, radial load and overturning moment and other comprehensive loads at the same time. Construction machinery is the initial application of slewing bearings, and it is also most widely used. We are specialized in the production of engineering machinery slewing bearings, drive shafts and matched pinions. For some common model excavators slewing bearing, we have ready stock and can deliver within one week. Our company has a special quality testing laboratory, devoted to product design and development, product application and testing methods. At the same time, the company also has advanced production equipment and testing equipment to ensure that products have high performance, long life, low friction, high precision.

Excavator is one of the important equipment in modern engineering construction. The reason why the excavator can turn left and right in the work is because of the slewing mechanism, which is one of the important components of the hydraulic excavator. The slewing mechanism is connected with the traveling device through a slewing bearing, and the slewing drive device makes the platform rotate relative to the traveling device, and drives the working device to rotate around its central axis of rotation. We are specialized in the production of engineering machinery slewing bearings, drive shafts and matched pinions. For some common model excavators slewing bearing, we have ready stock and can deliver within one week. Our company has a special quality testing laboratory, devoted to product design and development, product application and testing methods. At the same time, the company also has advanced production equipment and testing equipment to ensure that products have high performance, long life, low friction, high precision.

Swing bearing is widely used in excavator equipment like excavators. It is wear parts. We are specialized in the production of engineering machinery slewing bearings, drive shafts and matched pinions. If you need replacements of the steel balls, rollers or spacers, it is also available. For some common model excavators slewing bearing, we have ready stock and can deliver within one week. SK200, SK450 is the hot selling models. If you have old slewing bearing in hand, we can instruct you to measure the detailed size to make a professional drawing and then manufacture it for you.
