Product Overview: The 7002 Angular Contact Ball Bearing
The 7002 bearing is a single-row angular contact ball bearing designed for high-precision applications that require support for combined (radial and axial) loads. As a key component in our 7000 Series, this bearing is engineered to accommodate axial loads in one direction only. For this reason, they are typically mounted in pairs. The internal design, featuring a specific contact angle between the raceways and the balls, allows for high-speed operation and provides a high degree of system rigidity, making it an essential part of our comprehensive Angular Contact Ball Bearings collection.
Manufactured to exacting industry standards, the 7002 bearing ensures reliable performance and durability. Its ability to handle both radial and axial forces simultaneously makes it a versatile solution for a wide range of sophisticated machinery and equipment where precision and speed are paramount.
Key Features of the 7002 Bearing
- Combined Load Capacity: Designed to support both radial and axial loads simultaneously, with a high thrust capacity in a single direction.
- High-Speed Performance: Engineered with a precise internal geometry that minimizes friction and allows for high rotational speeds.
