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.

The single row cross roller slewing bearing is made of two seat rings. It is featured with compact structure, light weight, high manufacturing accuracy, small assembly gap and high requirement for installation accuracy. Rollers are 1:1 cross- arranged through spacers. It can bear axial force, overturning moment and large radial force at the same time. Compared with ball slewing ring, the axial and radial clearance of the cross roller slewing ring is smaller than single row ball slewing bearing. While the rotating is not so flexible as the single row ball slewing bearings, usually it is used for some higher precision applications. It is widely used in lifting transportation, construction machinery, military product, robots, medical equipment, grinding and drilling machine etc. Standard material we adopt is 50Mn and 42CrMo. Other customized material is also acceptable. We support models selection based on your application; teeth quenching and grinding; customized surface treatment like Blackening, phosphating, galvanizing, sandblasting and etc.

Light series slewing bearings are usually used on filling machine, which has the same structure as ordinary slewing bearing, but it has the characteristics of lightweight, flexible rotation, compact structure and low friction. This kind of slewing ring bearing is widely used in food machinery, filling machinery, beverage machinery, blow molding machine, packaging machinery, injection molding machine, environmental protection machinery, and other fields. It is with features of low noise, high precision and high performance. Adhering to the international advanced management concept, we are committed to providing a complete set of bearing solutions, from raw material control, rolling element, cage and anti-rust oil, grease, bearing lathe processing, heat treatment to rough grinding and fine grinding, bearing packaging and delivery, after-sales service , installation guidance, all-round service in accordance with international standards

Slewing ring is widely used in construction 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. 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. 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.

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.

Three-row roller slewing bearing has three seat rings, the upper and lower raceways and the radial raceways are separated. The upper and lower rows of rollers are arranged horizontally, and the middle row of rollers is arranged vertically. It can be made into an inner gear ring or an outer gear ring according to the equipment structure and work needs. The axial force and tilting moment in the two directions are borne by the upper and lower horizontal rollers, and the radial force is borne by the vertically arranged third row of rollers. According to the different characteristics of the load, the upper and lower rows of rollers can be of the same diameter or of different diameters. So that the load of each row of roller can be determined accurately. Being able to bear all kinds of loads at the same time, it is the largest one of the four structural products with large axial and radial dimensions and firm structure. It is especially suitable for heavy machinery requiring larger diameter, such as bucket wheel stacker and declaimer, wheel crane, marine crane, port crane, ladle turret and large tonnage truck crane, heavy machinery and so on.

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.
