  • 7001A-DF-Angular contact ball bearings for precision machinery
PREV：7002C SU-Angular contact ball bearings for precision machinery NEXT：7001A DB-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.

key characteristics and considerations regarding miniature single-row angular contact ball bearings
A miniature single-row angular contact ball bearing is a type of rolling element bearing that is designed to accommodate both axial (thrust) and radial (perpendicular to the axis) loads. The term "miniature" refers to the compact size of the bearing, which is commonly used in applications where space is limited. Here are key characteristics and considerations regarding miniature single-row angular contact ball bearings:
Design:Single-row angular contact ball bearings have a single row of balls sandwiched between inner and outer raceways.
Angular Contact:The contact angle between the raceways and the balls is designed to be non-parallel. This configuration enables the bearing to handle both axial and radial loads simultaneously.
Miniature Size:Miniature bearings are typically smaller in size compared to standard bearings. They are commonly used in applications with tight space constraints, such as small machinery, instruments, or precision devices.
High-Speed Capability:Miniature angular contact ball bearings are often capable of high-speed rotation due to their design and precision manufacturing.
Material Selection:These bearings are often made from high-quality materials such as chrome steel or stainless steel, depending on factors like load capacity, corrosion resistance, and operating environment.
Seals or Shields:Miniature angular contact ball bearings may come with seals or shields to protect against contamination and retain lubrication.
Cage Material:The cage, which separates the balls and maintains their relative positions, is typically made of materials like steel, brass, or engineered polymers.
Applications:Common applications include small motors, robotics, medical devices, miniature gearboxes, and other precision instruments where space and performance are critical.
Axial and Radial Load Capacity:Miniature angular contact ball bearings are designed to handle both axial and radial loads, making them versatile for various applications.
Preload:Some miniature bearings may be preloaded during manufacturing to eliminate internal clearances and enhance rigidity.
High Stiffness:The angular contact design contributes to high stiffness, making these bearings suitable for applications where precision and control are crucial.
Limited Misalignment Tolerance:While miniature angular contact ball bearings can accommodate some misalignment, they are generally less forgiving than other types of bearings.
Noise and Vibration:Proper selection and installation contribute to minimizing noise and vibration in the system.
