Single Row Cross Roller Slewing Bearing-manufacture,factory,supplier from China

Cross roller bearing is a special kind of rolling bearing, which is widely used in mechanical field. It is designed to meet large size equipment that needs to operate under the requirements of high load capacity, high rigidity and high rotational accuracy. The cross roller bearing is composed of inner and outer rings, rollers, sealing rings and cages, and its structural advantages are that it can withstand both radial and axial loads, with high torque rigidity and running accuracy. The following will introduce the characteristics and applications of cross roller bearings in detail.

Slewing bearing has four series of toothless, external and internal toothed four-point contact ball bearings, double row angular contact ball bearings cross cylindrical roller bearings, cross tapered roller bearings and three row cylindrical roller composite bearings, of which four-point contact ball bearings have higher static load capacity, cross cylindrical roller has higher dynamic load capacity, The pre-interference of cross-tapered roller bearing can make the bearing have greater support rigidity and rotation accuracy.

RU cross roller bearings are also known as bearings. The main body of a rolling body usually uses cylindrical or tapered rollers to intersect a single flow path, separated by retainers or spacers, and arranged in a cross pattern. Therefore, the cross roller ring group can withstand loads in all directions, with a stiffness of 3-4 times higher than traditional models. RU cross roller bearing is lubricated by spray. Drilled shrinkage air mixes spray and lubricating oil to produce oil mist.

The single-row four-point contact ball slewing bearing has the characteristics of compact structure and light weight, which makes it widely used in construction machinery. Because the steel ball and the circular raceway contact at four points, this support can bear axial force, radial force and heeling moment at the same time, with high bearing capacity and stability. Applicable scope includes rotary conveyor, welding operator, small and medium-sized cranes, excavators and other construction machinery, is a multi-functional, efficient slewing support structure.

Structural features: The roller inside the cross roller bearing is combined in a cross arrangement, which makes the bearing able to withstand both radial and axial loads. There is a certain gap between the inner and outer rings, which can make the bearing maintain high rigidity when it is subjected to high torque load, and also has good rotation accuracy and stability. The design of the seal ring and cage of the cross roller bearing is also very important, which can effectively prevent dust and foreign matter from entering the bearing interior and extend its service life.

Tapered roller bearings are separate bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double and four-row tapered roller bearings according to the number of rollers installed. Single-row tapered roller bearings can support radial loads and axial loads in one direction.The type code of tapered roller bearings is 30,000, and tapered roller bearings are separable bearings.

A single-row tapered roller bearing has an outer ring, and its inner ring and a group of tapered rollers are enclosed by a basket cage into an inner ring assembly, and the outer ring and the inner ring assembly can be separated. In addition, single-row tapered roller bearings can adjust the size of the clearance during installation.

Bearing performance: The bearing capacity of cross roller bearings is large, suitable for high-speed and high-load applications. Due to the special arrangement of rollers, the bearing can share part of the load when bearing radial and axial loads, which improves the bearing capacity and stability.

Applications: Cross roller bearings are widely used in many fields, including machine tools, engineering machinery, medical equipment, food packaging machinery, etc. On machine tools, cross roller bearings are often used to support the spindle and the turntable to ensure the high-speed and high-load operation of the equipment.

Single row tapered roller bearing is a common rolling bearing, which is composed of an inner ring, an outer ring, a roller and a cage. Its structure is similar to a conical shape, which is why it gets its name.The contact points on the inner and outer rings are conical and suitable for bearing large loads in both radial and axial directions.

1) Less coefficient of friction, High limiting speed, Large size range, Variations of structure.2) Tapered Roller Bearings are designed such like cup. Cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis.3) Single-row tapered roller bearing is able to carry radial and axial load in one directionssimultaneously because an axial component of produced when this type of bearings loadedradically, two bearings are used together facing one another, or two or more bearings arematched and used.

Four row tapered roller bearings are mainly used for work rolls, support rolls, and billet breakers of various plate and strip rolling mills. The clearance of the bearing is changed by adjusting the thickness of the spacer to make it more suitable for the working condition.1. Strong bearing capacity: four row tapered roller bearings can withstand greater loads under the same size, because it is shared by multiple rollers, so it has higher carrying capacity and better distribution performance.2.

Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings are equipped with tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed. Single-row tapered roller bearings can withstand radial loads and axial loads in a single direction.
