slew bearing

  • Customizable rotary bearings for construction machinery

    In the production process of slewing ring bearing, whole process inspection is implemented strictly to ensure that each set of products are qualified. For high-precision products, precise grinding is used to effectively control the parameters of ring ellipse, wall thickness and flatness, so as to ensure that the precision of finished products meets the requirements of standards or customer drawings.

  • Single Row Cross Roller Slewing Bearing (11 Series)

    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.

  • Single Row Four Point Contact Ball Slewing Bearing( 01 Series)

    Single row four point contact ball slewing bearing 01 series is a standard model series in China. It is made of two seat rings. The balls and the raceway are with four points contact, via which the axial force, radial force and resultant moment is born simultaneously. Outer Diameter is from 280mm to 4726mm. Most models slewing ring are with ready stock or semi-finished material stock, which can deliver out within 15 days. 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. In the production process of slewing ring bearing, whole process inspection is implemented strictly to ensure that each set of products are qualified. For high-precision products, precise grinding is used to effectively control the parameters of ring ellipse, wall thickness and flatness, so as to ensure that the precision of finished products meets the requirements of standards or customer drawings. This series models are with advantage of compact design, flexible rotating and light weight. It is widely used on rotary conveyor, welding arm and positioner, light/medium duty cranes, excavators and other engineering machines. Please feel free to tell us the application you use and we can help you choose the proper model and offer you a professional solution as soon as possible.

  • Swing Bearing For Hyundai

    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 inseparable from the credit 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.

  • High Performance Slewing Bearing For Crane

    Slewing bearing is an important "joint" of the crane. Various loads and moments on the working device need to be transmitted to the chassis through the slewing bearing. Because the slewing bearing is overloaded, it is also the part where the crane is prone to failure, so it is necessary to install a new slewing bearing after long-term use. Truck cranes, crawler cranes and other heavy construction cranes are usually using large single row four-point contact ball slewing ring bearing. This type of slewing bearing can bear larger axial load, radial load and tilting moment, enabling crane to lift heavy loads stably and reliably. To improve the manufacturing accuracy and working life of the slewing bearing, we focus on the heat treatment process, raceway quenching to prevent quenching cracks on the surface of the raceway. For high precision products, precise grinding is used to effectively control the parameters of ring ellipse, wall thickness and flatness, so as to ensure that the precision of finished products meets the requirements of standards or customer drawings. So our slewing bearings are with features of high precision, long working life and durable to use.

  • High Efficient Slewing Bearing For Stacker Reclaimer

    Bucket wheel machine, also known as bucket wheel stacker and reclaimer, is an efficient equipment for continuous loading and unloading of bulk bulk materials in modern industries. It has been widely used in ports, wharfs, metallurgy, cement, steel plants, coking plants, coal storage plants, power plants, etc. The stacking operation of bulk material (ore, coal, coke, sand and gravel) storage yard. The function of the slewing bearing of the bucket wheel stacker and reclaimer is to support the slewing structure, bear the vertical direction force, horizontal force and tilting moment generated by the slewing structure during operation and non-operation, so that the machine is in a stable state. In view of its working conditions, there are two commonly used slewing bearing structures, one is a heavy-duty external tooth single-row cross-roller slewing bearing, such as 1797/2100, 1797/2460, 1797/2500, 1797/2600, 1797/2635 , 1797/3230, etc.; the other is a three-row roller slewing bearing with external teeth, such as 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. These are the models that our company often makes. For detailed information, please call for consultation. If non-standard customization is required, our company can provide technical support such as selection, design, calculation, etc., you can call for details.
