Angular Contact Double Row Ball Bearing-manufacture,factory,supplier from China

Double row angular contact ball bearings correspond, in their design and operation, to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space.

Angular contact ball bearing has high limit rotational speed, they can carry radial load and axial load simultaneously, they can also withstand purely radial load. The axial load carrying capacity depends on the magnitude of contact angle and increases with increasing contact angle. Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools, for which high running accuracy is required.Single row angular contact ball bearings can carry axial load acting in one direction only.

High Rigidity and Stability: miniature angular contact bearings maintain their shape and rigidity when subjected to heavy loads, contributing to enhanced system stability and reduced risk of deformation.Optimized Lubrication Performance: They possess exceptional lubrication characteristics, reducing friction and wear between components, thus extending the bearing's lifespan and ensuring smooth operation.Versatility in Applications: axial angular contact ball bearing are adaptable to various environmental conditions, temperatures, and work environments, making them suitable for a wide range

Advantage of 7020C BearingWhen using the bearing, pay attention to make the raceway on one side without ball loading notch bear the main load.The locking port of this kind of bearing is on the outer ring.Generally, the inner and outer rings cannot be separated, and can bear the combined radial and axial load and the axial load in one direction.The ability to bear axial load is determined by the contact angle.The larger the contact angle, the higher the ability to bear axial load.Angular contact ball bearings are mainly divided into single row angular contact ball bearings and double row angula

Double row angular contact ball bearings can bear large radial loads, mainly radial and axial combined loads and torque loads, limiting the axial displacement of both sides of the shaft.

Single Row Angular Contact BearingsThese single row angular contact bearings are suitable for general use where axial loads are applied in only one direction. They are stand-alone bearings and are not designed to be combined or mated with another bearing.Double Angular Contact BearingsDuplex bearings are two matched bearings that provide precise alignment both radially and axially. By using duplex bearings, vibrations can be eliminated and higher load capacities can be achieved.

Angular contact ball bearing 70000 type, composed of outer ring, inner ring, steel ball, cage.

Single row angular contact ball bearings mainly used forundertaking combined load both from radius and axle andalso for pure axle load,rotator speed is high.Material of bearings is choosed on refining bearing steelGCr15 (100Cr6，SUJ2,S2100) and other type of bearingsteel,balls are adopting GCr15 (100Cr6，SUJ2,S2100) orceramic. The bearings are classified as 7000C (15°)70000AC(25°)、7000B (40) in accordance with theircontact angle,other bearings with different contact angular areavailable on request.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)G

A single row angular contact bearing is a common type of bearing, usually consisting of an inner ring, an outer ring, a retainer and a rolling element. It is designed so that the bearing can withstand radial, axial or combined loads when rolling.

BE=Single Row Angular Contact Ball Bearing With A 40° Contact Angle And Optimized Internal Design. CB=Bearing For Universal Matching. Two Bearings Arranged Back-To-Back Or Face-To-Face Will Have A Normal Axial Internal Clearance Before Mounting. M=Machined Window-Type Brass Cage, Ball Centered, Different Designs Are Identified By A Figure, e.g.

Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis, which means that they are designed to accommodate combined loads, i.e. simultaneously supporting radial and axial loads.The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle.

It uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each.

Angular contact ball bearings are of a non-separation design, and the shoulders on both sides of the inner and outer rings are not high or low. In order to increase the load capacity of the bearing, the shoulder on one side is machined lower, so that the bearing can fit more steel balls.Single row angular contact ball bearings can only withstand one direction of the axial load, in the radial load, will cause additional axial force, must apply the corresponding reverse load, therefore, this kind of bearings are generally used in pairs.

Retentors, usually made of steel or synthetic materials, are used to hold rolling elements in position, ensuring that they maintain the correct clearance and position relationship with each other during use.Single-row angular contact bearings are suitable for all kinds of rotating machinery, such as automobile wheels, motors, fans, etc., which can withstand high-speed operation and large loads.When installing, it is necessary to pay attention to the cleaning and lubrication of the bearing to ensure its performance and life.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter

As a kind of high-precision, high-strength, high-speed parts, automobile bearings have an absolute linking role, especially in the automobile chassis, engine, gearbox, brake disc, suspension, etc. There are a lot of bearings, so the life expectancy And quality is also a topic of concern to most people.After all, driving safety is more than everything. As a mainstream trend now, new energy vehicles are naturally very concerned about lightweight bearings.Bearings of new technology have also put forward new standards for high temperature resistance, high speed and light weight.

The sealing structure of the flange bearing is indeed crucial, because it can effectively protect the inside of the bearing from the intrusion of external impurities, thereby reducing the wear and failure of the bearing. Choosing the appropriate sealing structure can improve the reliability and stability of the equipment and extend the service life of the bearing. If you have any questions about the sealing structure or bearing performance, please continue to communicate with me.

NTN tapered roller bearings are mainly used to bear radial and axial combined loads mainly based on radial loads, with high stiffness and rotation accuracy, and have large bearing capacity and low limit speed compared with angular contact ball bearings. Its carrying capacity depends on the Angle of the raceway of the outer ring, and the greater the Angle, the greater the carrying capacity.
