7013 CD/P4ADT Bearing Product Overview & Core Advantages
The 7013 CD/P4ADT is a precision angular contact ball bearing configured in a Duplex Tandem (DT) arrangement. This matched pair is designed to deliver exceptional performance in applications requiring high rigidity and the ability to accommodate significant axial loads in one direction. Manufactured to the exacting P4A tolerance class, it ensures superior running accuracy and rotational precision. Its preloaded duplex design eliminates internal clearance, making it ideal for high-speed spindles and other precision machinery where minimal deflection and maximum system stiffness are critical.
7013 CD/P4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7013 | Basic bearing designation indicating a metric series angular contact ball bearing with a 65 mm bore, 100 mm OD, and 36 mm width. |
| CD | Indicates a Duplex Tandem (DT) arrangement. In this configuration, two bearings are mounted together to increase axial load capacity in a single direction. |
| P4A | Denotes a high-precision tolerance class with enhanced dimensional and running accuracy requirements, suitable for the most demanding applications. |
| Open | Specifies that the bearing has no integral seals or shields, allowing for higher limiting speeds and custom lubrication schemes. |
7013 CD/P4ADT Bearing Structural Features & Performance Benefits
- High Rigidity & Axial Load Capacity: The Duplex Tandem (DT) arrangement combines two bearings to form a single, highly rigid unit. This configuration is specifically engineered to handle heavy axial loads in one direction, providing exceptional stability and resistance to deflection under thrust forces.
- Precision Performance: Manufactured to P4A tolerance class standards, this bearing guarantees minimal runout and vibration, which is essential for maintaining high positional accuracy in precision equipment.
- Optimized for High Speeds: The phenolic resin cage is lightweight and robust, contributing to lower friction and enabling a high limiting speed of 24,000 rpm. The open design further facilitates efficient heat dissipation.
- Superior Material & Construction: Made from high-grade chrome steel for both rings and balls, the bearing offers excellent durability and fatigue resistance. The 15° contact angle provides an optimal balance between radial and axial load carrying capabilities.
7013 CD/P4ADT Bearing Typical Application Areas
The 7013 CD/P4ADT is ideally suited for high-performance applications where precision, speed, and unidirectional axial load capacity are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling machines, high-frequency motor spindles.
- Pumps & Compressors: High-speed multi-stage pumps and compressors.
- Robotics & Automation: High-accuracy rotary joints and indexing tables.
