7005 CDTP/P4B Bearing Product Overview & Core Advantages
The 7005 CDTP/P4B is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to simultaneously handle combined radial and axial loads, this bearing features a 15° contact angle and is supplied with a preload (P4B) for enhanced system stiffness and precise shaft positioning. Its P4 (ABEC-7) tolerance class ensures superior running accuracy, making it an ideal choice for high-speed spindles and other precision machinery where minimal runout and vibration are critical.
7005 CDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 7005 | Basic bearing series designation, indicating a 25mm bore, 47mm OD, and 12mm width. |
| C | Specifies a 15° contact angle, optimized for high-speed operation and moderate axial load capacity. |
| D | Indicates the bearing is part of a matched set (Duplex) for preload or specific mounting arrangements. |
| TP | Denotes a Phenolic (synthetic resin) cage, which is lightweight and suitable for high-speed applications. |
| P4 | Specifies a high-precision tolerance class (ABEC-7), ensuring tight dimensional and running accuracy. |
| B | Indicates a specific preload level has been applied to the bearing for immediate operational stiffness. |
7005 CDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The P4 tolerance class and applied preload (P4B) work in tandem to deliver maximum system stiffness, reduce deflection under load, and maintain precise shaft alignment, which is crucial for machining accuracy.
- Optimized Load Capacity: The 15° contact angle is engineered to efficiently handle combined loads, providing a balanced performance for both radial and axial forces encountered in high-speed applications.
- Superior High-Speed Performance: The lightweight Phenolic (TP) cage minimizes centrifugal forces, reduces friction, and allows for a high limiting speed of 36,000 rpm. The open design facilitates efficient lubrication management.
- Premium Material Construction: Manufactured from Chrome Steel for rings and balls, the bearing offers high fatigue life and durability, capable of operating within a temperature range of -30°C to 110°C.
