PREV：7002A DB-Angular contact ball bearings for precision machinery NEXT：7002A-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.

Are there considerations for dustproof angular contact Ball Bearing angle and precision when choosing dustproof bearings?
there are considerations for angular contact angle and precision when choosing dustproof angular contact ball bearings. Both the angular contact angle and precision class are important factors that influence the performance of bearings, including their ability to handle dust and contaminants. Here are some considerations:
Angular Contact Angle:The angular contact angle is the angle formed between the line of contact of the ball and raceway and a line perpendicular to the bearing axis.
A higher contact angle provides increased axial load-carrying capacity and better resistance to axial forces. This is particularly important in applications where dustproofing is crucial because the bearing is less likely to be affected by axial loads.
In applications with heavy axial loads, a larger angular contact angle may be preferred for enhanced load-carrying capacity.
Higher precision classes are generally associated with tighter tolerances, resulting in bearings with improved accuracy, reduced runout, and better overall performance.
In dustproof applications, precision is essential to maintain consistent sealing effectiveness. A well-manufactured, precise bearing helps prevent gaps in the sealing mechanism that could allow contaminants to enter.
Combined Loads:Consider the nature of the loads in the application. Dustproof angular contact ball bearings are often used in environments where both radial and axial loads are present.
The choice of angular contact angle and precision should be suitable for handling the combination of loads that the bearing will experience.
Sealing Mechanism:Dustproof bearings usually incorporate seals or shields to prevent the ingress of contaminants. The design and effectiveness of these seals should be considered alongside the angular contact angle and precision to ensure comprehensive protection.
Application Requirements:Consider the specific requirements of the application. Some applications may prioritize higher precision for tasks such as high-speed machining, while others may prioritize load-carrying capacity and resistance to contamination.
Environment:
Evaluate the operating environment, including the level of dust and contaminants present. If the environment is particularly harsh, a combination of an effective sealing mechanism and appropriate angular contact angle can enhance the bearing's performance.
when choosing dustproof angular contact ball bearings, it's crucial to consider the angular contact angle, precision class, and other factors in the context of the application's requirements and operating conditions. The goal is to select a bearing that provides both effective dustproofing and optimal performance for the specific mechanical system.
