Product Overview: The 7005 Single-Row Angular Contact Ball Bearing
The 7005 bearing is a high-precision component engineered for applications demanding high speeds and the ability to support combined loads. As a key part of our 7000 Series and the broader Angular Contact Ball Bearings collection, this bearing features raceways in the inner and outer rings that are displaced relative to each other along the bearing axis. This specialized design allows it to accommodate both radial and axial loads simultaneously. With standard dimensions of 25x47x12mm (Bore x Outer Diameter x Thickness), the 7005 is built to provide exceptional rotational accuracy and rigidity, making it a preferred choice for precision machinery.
Key Features of the 7005 Bearing
- Combined Load Support: Expertly designed to handle both radial loads and a significant axial load in a single direction.
- High-Speed Capability: Its internal geometry is optimized for low friction and minimal heat generation, enabling reliable operation at high rotational speeds.
- Single-Direction Axial Support: Provides robust axial support in one direction, making it ideal for applications with a primary thrust load.
- High Rigidity: The specific contact angle offers a high degree of stiffness, which is essential for maintaining shaft alignment and operational precision.
- Versatile Pairing Options: Can be mounted in pairs (back-to-back, face-to-face, or tandem arrangements) to handle axial loads in both directions or to increase load capacity.
- Precision Manufacturing: Produced from high-quality bearing steel to strict tolerances, ensuring consistent performance and a long service life.
Common Applications of 7005 Bearings
- Machine Tool Spindles: Widely used in lathes, milling machines, and grinders where precision and rigidity are critical.
- High-Speed Pumps: Ensures stable and efficient operation in various industrial pumps, including centrifugal and screw types.
- Electric Motors: Provides reliable support for motor shafts, especially in high-performance or vertically mounted motors.
