709 Series Precision Angular Contact Ball Bearings
The 709 series includes 709C and 709AC angular contact ball bearing configurations in a compact 9 × 24 × 7 mm size. These bearings support combined radial and axial loads in rotating and positioning assemblies. The listed configurations include DB back-to-back, DF face-to-face and universally matchable specifications.
Phenolic and nylon cage configurations are included in the product range. The series can be considered for high speed spindles, engraving and PCB drilling spindles, precision grinding and CNC lathe spindles, high frequency motors, precision instruments, compact linear modules and rotary stages.
The appropriate model, cage material and bearing arrangement should be selected according to the working speed, load direction, required accuracy, lubrication, operating temperature and installation conditions. Please provide the full bearing designation and application requirements so configuration availability and suitability can be confirmed before ordering.

PRIMARY FUNCTION & CAPABILITY
The core function of an Angular Contact Ball Bearing is to support combined radial and axial loads acting in tandem. Unlike deep groove ball bearings, they are specifically optimized to handle high axial forces, making them ideal for applications where shafts must be positioned accurately with minimal axial play.
MAIN APPLICATIONS
These bearings are critical components in high-precision and high-speed machinery across numerous industries:
Machine Tool Spindles:
CNC machining centers, lathes, and grinders where high rigidity, speed, and accuracy are paramount.
Power Transmission:
Gearboxes, pumps, and compressors.
Automotive:
High-performance wheel hubs, transmissions, and electric vehicle motors.
Aerospace:
Helicopter transmissions, jet engine components, and landing gear systems.
Robotics & Automation:
High-precision joints, rotary tables, and servo motors.
Agricultural & Construction Machinery:
Heavy-duty applications require robust performance.
