Detailed description of rolling bearing precision grade and selection

Bearing is one of the commonly used parts in mechanical equipment, due to the different precision requirements of the equipment, plus the bearing precision provided by different manufacturers are also different.But no matter how the requirements of the bearing precision, for the bearing precision or there is a level of standard, in addition, the choice […]

Maintenance work of the rotary mechanism of the drilling rig

During the use of the drilling rig, the problems that are prone to occur in the slewing system are the wear of the slewing bearing steel ball, the pitting of the output gear of the slewing reducer, and the wear of the slewing brake friction plate. How to reduce the occurrence of the above-mentioned problems […]

Pretightening requirements for turntable bearing bolts

The connection of the turntable bearing depends on fasteners such as bolts, so the quality choice of bolts and the way of loading and unloading will affect the performance of the turntable bearing.Today, let us introduce you about the pre-tightening requirements of the turntable bearing bolts. The purpose of preloading is to increase the reliability […]

Influence of bearing steel material on turntable bearing

The wide application of slewing bearings requires the production industry to continuously innovate product forms and improve product performance in product design. Because it’s main performance is closely related to product material selection, there are multiple considerations in manufacturing and material selection. Today, the editor will analyze and explain the influence of bearing steel materials […]

What are the commonly used materials of slewing bearing

Slewing bearings, also called slewing bearings, are often used in engineering and manufacturing machinery, such as excavators, roadheaders, wind power equipment, industrial robots, port machinery and other equipment. Slewing bearings are usually composed of ferrules, rolling elements, cages, and sealing rings. Because different parts have special functions in practical applications, there are different considerations in […]

Research and analysis on the usability of slewing bearings

The slewing bearing is a large bearing that can bear large axial load, radial load and overturning moment at the same time. Turntable bearings are generally equipped with mounting holes, internal or external gears, lubricating oil holes and sealing devices, which can make the mainframe structure compact, reliable guidance, and convenient maintenance. It is widely […]
