709 CD/P4A Bearing Product Overview & Core Advantages
The 709 CD/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Designed to accommodate primarily combined radial and axial loads in one direction, this bearing features a 15° contact angle and is supplied with a P4 (ABEC-7) tolerance class for superior running accuracy. Its compact design, with a 9 mm bore and 7 mm width, makes it ideal for space-constrained, high-speed machinery demanding reliable performance.
709 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model number 709 CD/P4A provides specific technical information:
- 709: Basic bearing series, indicating a metric, light series angular contact bearing.
- C: Denotes a 15° contact angle, optimized for high-speed operation and moderate axial load capacity.
- D: Indicates the bearing is supplied with a preload for enhanced rigidity and reduced axial/radial play.
- P4A: Specifies the tolerance class P4 (ABEC-7), ensuring very high dimensional and running accuracy.
709 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design with phenolic cage and P4 precision ensures minimal vibration and high running accuracy, essential for spindle applications.
- Optimized Load Capacity: The 15° contact angle effectively handles combined loads, providing robust support for both radial and significant one-direction axial forces.
- Superior High-Speed Performance: The lightweight phenolic resin cage and optimized internal geometry contribute to a high limiting speed of 120,000 rpm, making it suitable for demanding high-speed operations.
- Pre-lubricated and Open Design: The bearing comes pre-lubricatedopen seal type allows for custom lubrication regimes in controlled environments, maximizing performance flexibility.
709 CD/P4A Bearing Typical Application Areas
This precision bearing is ideally suited for:
- Machine Tool Spindles
- High-Speed Grinding and Milling Heads
- Precision Instrumentation and Medical Devices
- High-Frequency Motors and Pumps
- Robotic Arm Joints and Actuators
