The application of slewing bearings(slew ring)

Apr 26, 2020

The main application of slewing bearings(slew ring)

Slewing bearing (slewing ring) is a kind of large rolling bearing that can carry axial loads, radial loads and overturning moments, and with high load capacity. The biggest feature of the slewing bearing is that it has large overturning moments (eccentric load), which makes the slewing bearing have a very wide range of applications.

CHG company can design and manufacture slewing bearings with different operating conditions, different specifications and different precision grades. The models cover 100mm-5000mm various standard or non-standard slewing bearings, which are widely used in lifting machinery, metallurgical mining machinery, ship port machinery, Construction machinery, medical machinery, high-precision machine tool turntable, military equipment, wind power, engineering vehicle machinery, petrochemical machinery, engineering machinery and other industries. We can design and produce a variety of non-standard slewing bearings to meet your needs according to your specific needs.

The application field and application equipment of slewing bearings as follows:

Slewing bearings have widely applications. Engineering machinery is the most widely used place for slewing bearings, such as Earth moving machinery, Excavators, Disintegration machines, Stacker reclaimers, graders, road rollers, powerful boring machines, rock drilling machines, etc.

1. Trailer: This type of slewing bearing is used in a variety of occasions, the most important of which is used in the transport industry, agricultural trailers, irrigation systems and airport luggage racks. In the application of vehicles, the axial load, radial load and torque of bearings are transferred. In other applications, they mostly transmit axial loads. CHG specializes in manufacturing slewing bearings for trailers.

2. Wind power: Wind turbine bearings usually include yaw bearings, propeller bearings, drive system bearings (spindle and gearbox bearings). CHG provides yaw bearing and variable propeller bearing for customers. Yaw bearing is installed in the connection part between tower and cockpit, and pitch bearing is installed in the connection part between the root of each blade and hub. Each wind turbine has one set of yaw bearing and three sets of pitch bearing.

3. Solar energy: Rotating solar panels are a good way to increase energy. Because CHG bearings have a very compact design, they supply slewing bearing for solar farm in Europe .

4. Medical Devices: CHG slewing bearing has been widely used in gamma knife, CT machine, nuclear magnetic resonance machine and other large medical devices.

5. Robots: Industrial robots and other equipment.CHG turntable bearings are mounted on the joints of robots, and this structure can achieve incredible high-compact rotational motion.

CHG Bearing:The lifespan of bearings
Mar 28, 2024
The bearing life refers to the number of revolutions or hours experienced by the bearing before the occurrence of pitting under a certain load. The life of rolling bearings is usually defined by the number of revolutions or the number of hours worked at a certain speed. During this lifespan, no initial fatigue damage (such as spalling or defects) should occur on any bearing ring or rolling element.
Assembly and disassembly of tapered roller bearings
Mar 21, 2024
Tapered roller bearings can be mounted directly on a tapered shaft or on a cylindrical shaft through an adapter sleeve or withdrawal sleeve. A tight fit is obtained by axially moving the inner ring. The tight fit of the inner ring can be effectively controlled by measuring the reduction in radial clearance caused by the expansion of the inner ring.
Four row tapered roller bearings
Mar 14, 2024
It usually consists of two double-row inner rings, a double-row outer ring and two single outer rings. There is an inner spacer ring between the two inner rings, and there are two middle spacer rings between the three outer rings. Such a design The bearing can adjust the clearance to adapt to different working conditions.
Application of rolling mill bearings
Feb 28, 2024
Rolling mill bearings should be selected according to the type and working characteristics of the rolling mill. 1. Billet opening machine and billet mill: This type of rolling mill generally has a large rolling force and strong impact load, but the speed is not high;
