C3 Double Row Angular Contact Ball Bearing 3212A-manufacture,factory,supplier from China

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

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.

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

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

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

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.

Double row angular contact ball bearings, from automotive hub bearings series a high load capacity, high roll stiffness, double sealCorrosion protection machined bearing housing2. Threaded pin with positioning surface3. Lock washer4. There are high-performance three-lip box seals on both sides of the bearing to prevent pollution.

NTN angular contact bearing is a commonly used bearing type with excellent load bearing performance and stable rotation accuracy. This kind of bearing is usually composed of inner and outer rails and steel balls and other components, and is suitable for various mechanical equipment and transmission systems. The structural design of NTN angular contact bearings is called the contact Angle, which has the ability of the inner and outer rings to withstand radial and axial loads.

Angular contact thrust ball bearings consist of an inner, outer ring, cage, steel ball and groove, and an inner/outer ring with a spherical surface, which can withstand unidirectional and bidirectional axial loads and slight radial loads.

Aligning roller bearings have two rows of rollers, mainly bearing radial loads, but also can withstand axial loads in either direction. It has high radial load capacity, especially suitable for heavy loads or dynamic loads, but cannot withstand pure axial loads. This kind of bearing outer ring raceway is spherical shape, so its aligning performance is good, can compensate for the coaxial error.Self-aligning roller bearings are divided into two different structures according to the roller cross section shape: symmetrical spherical roller bearings and asymmetric spherical roller bearings.

(1),High-speed bearing: has the advantages of cold resistance, low mechanical elasticity, high pressure resistance, poor thermal conductivity, light weight, small friction coefficient, etc., can be used in 12000 RPM - 75,000 RPM high-speed spindle and other high-precision equipment;(2), High temperature bearing: the material itself has a high temperature resistance of 1200 ° C, and self-lubrication, the use of temperature between 100 ° C -800 ° C does not produce expansion caused by temperature difference.

Mainly bear a large unidirectional axial load, the greater the contact Angle, the greater the load bearing capacity. The cage material is steel plate, brass or engineering plastic, and the forming method is stamping or turning, depending on the bearing form or use conditions.

The hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It combines two sets of bearings into one, with good assembly performance, clearance adjustment can be omitted, light weight, compact structure, and high load capacity. Large, unsealed bearings can be loaded with grease in advance, omit the external hub seal and avoid maintenance, etc., have been widely used in cars, and there is a tendency to gradually expand their application in trucks.

Since a bearing can choose different bearing seats, and a bearing seat can choose different types of bearings at the same time, there are many varieties of bearing seats. Bearing seat is included, many large foreign bearing companies also have their own bearing seat type record. However, the same bearing housing model is not marked exactly the same in different company samples.

The inner and outer rings are made of high-quality bearing steel material, with good hardness and wear resistance, and can withstand high-speed rotation and heavy load conditions.The roller adopts cylindrical or conical design, which can effectively share the radial and axial load, reduce rolling friction, and improve the rotation efficiency of the bearing.The cage is made of steel or copper material, with good strength and toughness, which can support the roller stably and extend the service life of the bearing during high-speed operation.The aligning design can automatically adjust the relat
