PREV：7306AC-Angular contact ball bearings for precision machinery NEXT：7305AC-Angular contact ball bearings for precision machinery
Product description Technical parameter
Precision angular contact ball bearing, belongs to the deep groove ball bearing deformation structure, suitable for all kinds of precision machinery selection, this series of bearings can bear radial load and axial load at the same time, can work at a higher speed. The larger the contact angle, the higher the axial load carrying capacity. According to the axial load size, contact angle is mainly divided into C-15 degrees, AC-25 degrees, A-30 degrees, B-40 degrees type structure, small friction coefficient, high limit speed, high manufacturing accuracy, can provide high-speed ceramic ball series bearings and sealed series bearings, cage mainly organic processing window brass cage, steel plate stamping cage, glass fiber reinforced nylon cage (nylon), and phenolic Laminated cloth tube cage (rubber wood), also can provide universal pair and any pair combination bearings. Mainly used in: machine tool spindles, high frequency motors, gas turbines, centrifugal separators, small car front wheels, differential pinion shafts, booster pumps, drilling platforms, food machinery, indexing heads, welding machines, low-noise cooling towers, electromechanical equipment, coating equipment, machine tool groove plates, arc welding machines, water pumps, modules, and support seats.

The Anatomy of Silent Precision Angular Contact Ball Bearings
1.Inner and Outer Rings: The inner and outer rings of Silent Precision Angular Contact Ball Bearings play a pivotal role in their performance. These rings are meticulously crafted from high-quality materials, often chrome steel or ceramics, to ensure exceptional strength, durability, and resistance to wear. The precision machining of these rings involves grinding and honing processes to achieve the required tolerances, contributing to the overall stability and reliability of the bearing.
2.Balls: The balls within these bearings are designed to facilitate smooth and precise motion. Typically made from chrome steel or ceramics, they undergo stringent manufacturing processes such as heat treatment and polishing to ensure uniform size and surface finish. The symmetrical arrangement of balls in the bearing assembly allows for even load distribution, reducing friction and enhancing the overall efficiency of the bearing.
3.Cages: Silent Precision Angular Contact Ball Bearings employ cages to maintain proper ball spacing and alignment within the bearing assembly. These cages are crafted from materials like engineered polymers or high-quality steel, providing stability while minimizing friction. The cage design is crucial for preventing ball-to-ball contact, thus reducing wear, heat generation, and noise during operation.
4.Seals: Seals are integral components that protect Silent Precision Angular Contact Ball Bearings from contaminants and retain lubrication. The choice of sealing materials, such as rubber or metal, is critical in ensuring a secure barrier against dust, moisture, and other environmental elements. Effective sealing not only enhances the bearing's lifespan but also contributes to its silent operation by preventing the ingress of foreign particles.

Material Selection for Silent Precision Angular Contact Ball Bearings
The selection of materials for Silent Precision Angular Contact Ball Bearings is a paramount consideration in achieving optimal performance. Chrome steel remains a popular choice due to its excellent strength, corrosion resistance, and durability. Ceramic materials, such as silicon nitride, are gaining prominence for their exceptional hardness, reduced friction, and resistance to high temperatures. The precise metallurgical composition of these materials ensures a uniform microstructure, minimizing the risk of defects that could compromise the bearing's performance. Additionally, the heat treatment processes applied to these materials enhance their hardness and fatigue resistance, contributing to prolonged bearing life even under heavy loads and high-speed conditions. The combination of advanced materials and meticulous manufacturing processes distinguishes Silent Precision Angular Contact Ball Bearings, positioning them as reliable components capable of withstanding demanding operational environments.

Lubrication Strategies for Enhanced Performance
Lubrication is a critical factor influencing the efficiency and longevity of Silent Precision Angular Contact Ball Bearings. The choice between grease and oil lubrication depends on the specific application requirements.
1.Grease Lubrication: Grease is commonly used in applications where a semi-solid lubricant is preferred. It provides excellent sealing properties, protecting the bearing from contaminants and reducing maintenance frequency. The carefully formulated greases used in these bearings offer optimal viscosity, ensuring proper lubrication even in high-speed and high-temperature conditions.
2.Oil Lubrication: For applications demanding higher speeds or operating temperatures, oil lubrication is the preferred choice. The precise selection of oils, considering factors such as viscosity, temperature stability, and anti-wear additives, is crucial in maintaining low friction, dissipating heat effectively, and ensuring a smooth, silent operation over extended periods.
