7034 CD/P4ADGA Bearing Product Overview & Core Advantages
The 7034 CD/P4ADGA is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As part of a universally matchable (SU) set, it is engineered to accommodate combined loads—significant radial and axial loads in one direction. Its P4A tolerance class and extra light preload (Class A) ensure smooth, precise operation, making it an ideal solution for high-speed, high-rigidity spindles and other precision machinery where minimal deflection and maximum performance are critical.
7034 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7034 CD/P4ADGA provides a detailed technical specification:
- 7034: Basic designation indicating a 170 mm bore, 260 mm OD, and 84 mm width.
- C: Denotes a 15° contact angle, optimized for high-speed operation and high axial load capacity.
- D: Indicates the bearing is part of a universally matchable pair (SU). Two bearings can be arranged in tandem, back-to-back, or face-to-face configurations to suit specific load and rigidity requirements.
- P4A: Specifies the tolerance class, representing extremely high dimensional and running accuracy (superior to ABEC 7/ISO P4).
- DGA: Indicates the bearing is supplied lubricated and comes from the factory with a specific grease fill suitable for its operational temperature range.
7034 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: Manufactured to P4A tolerance standards with an extra light preload, this bearing provides superior shaft positioning accuracy and system stiffness, minimizing runout and vibration.
- Superior Load Capacity: The 15° contact angle and robust chrome steel construction enable high radial dynamic load rating (77,625 lbf) and static load rating (110,250 lbf), effectively handling combined loads.
- Optimized High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, contributing to a high limiting speed of 11,000 rpm. The universal matchable design allows for optimized preload in multi-bearing arrangements.
- Ready-to-Install: The bearing is supplied pre-lubricated, simplifying installation and ensuring immediate, reliable operation within its specified temperature range of -30°C to 110°C.
7034 CD/P4ADGA Bearing Typical Application Areas
The 7034 CD/P4ADGA is ideally suited for high-performance applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, high-frequency motor spindles.
- Industrial Pumps and Compressors: Where high speed and axial load capacity are required.
- Robotics and Automation: High-accuracy rotary joints and actuators.
