S7007 ACDTP/HCP4B Bearing Product Overview & Core Advantages
The S7007 ACDTP/HCP4B is a high-precision double row angular contact ball bearing engineered for demanding applications requiring exceptional rotational accuracy and rigidity. This sealed bearing is designed to accommodate combined loads (radial and axial loads from both directions) simultaneously. Its compact design, featuring a P4 (ABEC-7) tolerance class and a 25° contact angle, ensures high running accuracy and is ideal for high-speed, high-reliability machinery. The combination of a phenolic cage and ceramic balls contributes to its superior performance.
S7007 ACDTP/HCP4B Bearing Model Code Explained, Specifications & Naming Convention
The model number S7007 ACDTP/HCP4B is decoded as follows:
- S7007: Basic series designation, indicating a double row angular contact ball bearing with a 35mm bore.
- A: Denotes a 25° contact angle.
- CD: Indicates a high preload for maximum rigidity.
- T: Signifies the cage material is phenolic resin.
- P: Indicates the bearing is sealed on both sides.
- HCP4B: Specifies the P4 (ABEC-7) tolerance class and a special internal clearance/geometry optimized for high-precision applications.
S7007 ACDTP/HCP4B Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The double row design and application of a high preload (CD) provide exceptional stiffness, enabling the bearing to effectively support substantial combined loads and moments with minimal deflection.
- Superior High-Speed Performance: The lightweight phenolic cage (T) and low-density ceramic balls reduce centrifugal forces, allowing for a high limiting speed of 24,000 rpm. This makes it an excellent high-speed bearing.
- Reduced Maintenance & Long Service Life: The integral seals (P) protect against contamination and retain lubricant, creating a maintenance-free solution for the designated operating life. The use of ceramic balls also enhances durability by reducing wear and providing resistance to electrical erosion.
- Thermal Stability: The phenolic cage and ceramic balls offer stable performance across the specified temperature range from -30°C to 110°C.
S7007 ACDTP/HCP4B Bearing Typical Application Areas
This precision bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles: For high-speed milling, grinding, and turning centers requiring utmost precision and rigidity.
- High-Frequency Motors and Spindles: Used in applications for PCB drilling, dental handpieces, and small precision tools.
- Precision Instrumentation: Critical components in medical devices, optical scanners, and measuring equipment.
- Robotics: Arm joints and other high-accuracy, high-speed articulation points.
