S7007 CD/P4ADT Bearing Product Overview & Core Advantages
The S7007 CD/P4ADT is a precision angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This duplex tandem (DT) arrangement features two bearings preloaded against each other, delivering superior axial stiffness and enabling it to handle significant combined loads (radial and axial) simultaneously. Manufactured to the exacting P4A tolerance class, it guarantees high running accuracy and is pre-lubricated with grease for immediate operation, making it ideal for high-speed, high-precision spindles and machinery.
S7007 CD/P4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7007 | Basic bearing series and size designation (35mm bore, 62mm OD). |
| C | Specifies a 15° contact angle, optimized for high-speed operation and axial load capacity. |
| D | Indicates the bearing is part of a duplex pair. |
| P4A | Denotes a high-precision tolerance class with enhanced running accuracy requirements. |
| DT | Signifies the Duplex Tandem mounting arrangement, where two bearings are stacked to maximize axial load capacity and rigidity in one direction. |
S7007 CD/P4ADT Bearing Structural Features & Performance Benefits
- Superior Rigidity & Load Capacity: The duplex tandem design creates a highly rigid bearing system capable of withstanding heavy combined loads. This configuration significantly increases the axial load-carrying capacity compared to a single bearing.
- High-Speed Performance: The lightweight phenolic resin cage ensures stable operation and reduced centrifugal forces, contributing to the high limiting speed of 41,000 rpm. The standard 15° contact angle is ideal for such high-speed applications.
- Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, this bearing ensures minimal runout and vibration for superior performance in precision machinery.
- Ready-to-Install & Sealed: As a sealed bearing, it is protected from contamination. Being pre-lubricated with grease, it is a maintenance-free solution within its specified temperature range (-30°C to 110°C).
S7007 CD/P4ADT Bearing Typical Application Areas
This bearing is engineered for high-performance applications where precision, speed, and rigidity are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, engraving, and high-frequency motor spindles.
- High-Speed Automation: Robotics, CNC rotary tables, and indexing heads.
