  • 7000A DF-Angular contact ball bearings for precision machinery
PREV：7001C SU-Angular contact ball bearings for precision machinery NEXT：7000A 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.

What advantages do GCr15 Angular contact ball bearing offer in terms of protection against contaminants?
High Load-Carrying Capacity GCr15 Angular contact ball bearing 
GCr15 refers to a high-quality bearing steel often used in the manufacturing of bearings, including Angular Contact Ball Bearings. When considering protection against contaminants, GCr15 Angular Contact Ball Bearings offer several advantages:
Corrosion Resistance: GCr15 steel is known for its excellent corrosion resistance, providing a protective barrier against environmental factors that could lead to corrosion. This characteristic contributes to the bearings' ability to resist damage caused by contaminants.
Precision Manufacturing: GCr15 steel can be machined to very precise tolerances, allowing for the creation of high-precision bearings. This precision manufacturing reduces the likelihood of gaps or imperfections that could allow contaminants to enter the bearing.
Sealing Compatibility: GCr15 Angular Contact Ball Bearings can be effectively sealed to provide an additional layer of protection against contaminants. Seals, made from materials such as rubber or metal, help create a barrier that prevents dust, dirt, and other particles from reaching the bearing internals.
Reduced Wear: The hardness and wear resistance of GCr15 steel contribute to reduced wear and abrasion, even when subjected to challenging operating conditions. This results in a more reliable and longer-lasting bearing performance.
High Load-Carrying Capacity: GCr15 steel's combination of strength and hardness allows for the design of bearings with high load-carrying capacity. This is beneficial in applications where the bearings need to withstand heavy loads while remaining resistant to contaminants.
Premium GCr15 Steel: Our bearings are manufactured using high-quality GCr15 bearing steel, known for its exceptional strength, hardness, and wear resistance. This robust material forms the foundation for bearings capable of withstanding heavy loads without compromising performance.
Advanced Angular Contact Design: The angular contact design optimizes the contact angles between the balls and the raceways, distributing loads evenly. This results in superior axial and radial load-carrying capacity, making these bearings ideal for applications with demanding load requirements.
Heat Treatment for Durability: The GCr15 steel undergoes a specialized heat treatment process to enhance its hardness and durability. This treatment not only increases the bearing's load-carrying capacity but also ensures longevity under heavy and continuous use.
