Double Row Angular Contact Ball Bearing 3307-2RS-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.

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.

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

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.

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.

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.

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.

High load capacity: Thanks to the angular contact design, NTN angular contact ball bearings perform well in terms of load capacity and are suitable for high-speed operation and high-power transmission.High precision: NTN angular contact ball bearings are manufactured with high precision, which can ensure their stability, low noise and high performance during operation.High temperature resistance: NTN angular contact ball bearings are usually made of high temperature wear-resistant materials, which can maintain good operating performance in high temperature environments.High speed: NTN angular

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

Bearing capacity: NTN angular contact bearings have high bearing capacity and can withstand large radial and axial loads. In the process of use, the axial load of the bearing will cause the contact pressure between the inner and outer rings to increase, so it is necessary to choose the appropriate contact Angle to improve the bearing capacity.Rotation accuracy: NTN angular contact bearings have high rotation accuracy, which can ensure that the mechanical equipment has stable rotation performance during operation.
