slewing ring bearing for sale
1.What is the difference between a slewing ring bearing and a slewing bearing?
1. Different concepts
1. Slewing ring bearing
The slewing ring bearing is a new type of mechanical parts, which consists of inner and outer rings, rolling elements, etc. The slewing ring bearing is a large bearing that can withstand comprehensive loads, and can bear large axial and radial loads and overturning moments at the same time.
2. Slewing bearing
Slewing bearing is a kind of large bearing with special structure that can bear large axial load, radial load and overturning moment and other comprehensive loads at the same time.
Second, the structure is different
1. Slewing ring bearing
Slewing drive is usually composed of worm, slewing bearing, housing, motor and other components. Since the core component adopts slewing bearing, it can bear axial force, radial force and tipping moment at the same time. There are many forms, but the structure and composition are basically the same.
2. Slewing bearing
A slewing bearing is usually composed of four major components: inner ring, outer ring, rolling elements, and spacer blocks. Because the core component adopts slewing bearing, it can bear axial force and radial force at the same time. There are many forms, but the structure and composition are basically the same.
Three, different applications
1. Slewing bearing
Slewing ring bearings are widely used, and construction machinery is the first and most widely used place for slewing bearings, such as earth-moving machinery, excavators, disintegrators, stackers and reclaimers, graders, road rollers, dynamic compactors, rock drilling machinery, roadheaders, etc.
Others include concrete machinery: concrete pump truck, concrete mixing and placing boom integrated machine, belt placing machine Feeding machinery: disc feeder, sand mixer; lifting machinery: wheel crane, crawler crane, door Pedestal cranes, tower cranes, fork cranes, hoists, gantry cranes.
Ground treatment machinery: impact reverse circulation drilling rig, rotary drilling rig, impact rotary drilling rig, rotary drilling rig, reverse circulation rotary drilling rig, positive circulation rotary drilling rig, long spiral engineering drilling rig, diving engineering drilling rig, static pile driver, pile driver .
Engineering ships: dredgers; special vehicles: bridge inspection vehicles, fire trucks, window cleaning machines, flat beam transport vehicles, aerial work vehicles, self-propelled aerial work platforms; light industrial machinery: beverage machinery, bottle blowing machines, packaging machinery, Filling machine, rotary unscrambler, injection molding machine; marine crane: floating crane.

Slewing bearings are widely used, and construction machinery is the first and most widely used place for slewing bearings, such as earth-moving machinery, excavators, disintegrators, stackers and reclaimers, graders, road rollers, dynamic compactors, rock drilling machinery, roadheaders, etc.
Slewing ring bearings are also called slewing bearings, and some people also call them: slewing bearings and slewing bearings.
The English names are: slewing bearing, slewing ring bearing, turntable bearing and slewing ring.
Slewing bearing, also known as slewing bearing, is a large bearing that can bear large axial load, radial load and overturning moment at the same time.
The slewing bearing generally has mounting holes, internal gears or external gears, lubricating oil holes and sealing devices, so that the main engine has a compact design, reliable guidance and convenient maintenance.
Slewing bearings include gearless, external gear and internal gear four-point contact ball bearings, double-row angular contact ball bearings, crossed cylindrical roller bearings, crossed tapered roller bearings and three-row cylindrical roller combined slewing bearings, etc.
Various structural types. Among them, the four-point contact ball bearing has a higher static load capacity; the crossed cylindrical roller bearing has a higher dynamic load capacity; the crossed tapered roller bearing can make the bearing have greater support rigidity and higher rotation through pre-interference precision.
Slewing bearings are widely used in large-scale slewing devices such as lifting machinery, mining machinery, construction machinery, port machinery, marine machinery, and high-precision radar machinery and missile launchers.

Slewing ring bearings generally have mounting holes, internal 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.
The slewing ring bearings include four-point contact ball bearings with no gears, external gears and internal gears, double-row angular contact ball bearings, crossed cylindrical roller bearings, crossed tapered roller bearings and three-row cylindrical roller composite bearings.
series, in which the four-point contact ball bearing has a high static load capacity, the crossed cylindrical roller has a high dynamic load capacity, and the pre-interference of the crossed tapered roller bearing can make the bearing have greater support rigidity and rotation accuracy,
The three-row cylindrical roller combination bearing leads to the height of the bearing due to the improvement of the bearing capacity, and various forces are borne by different raceways, so under the same force, the bearing diameter can be greatly reduced, so the main engine is more compact.
A high load capacity slewing ring bearing. Slewing ring bearings are widely used in large-scale slewing devices such as hoisting machinery, mining machinery, construction machinery, port machinery, marine machinery and equipment, as well as high-precision radar machinery and missile launchers.
At the same time, it can also design, develop and produce various special structure slewing ring bearings according to the specific requirements of users. The basic structure of the slewing ring bearing.
