S7005 ACDTP/P4B Bearing Product Overview & Core Advantages
The S7005 ACDTP/P4B is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. This single-row bearing features a 25° contact angle and is supplied with a preload, enabling it to handle combined radial and axial loads simultaneously with high stability. Manufactured to a P4 (ABEC-7) tolerance class, it guarantees superior running accuracy, making it ideal for high-speed spindles and other precision machinery where minimal runout and high rotational accuracy are critical.
S7005 ACDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
The model number S7005 ACDTP/P4B provides detailed technical specifications:
- S7005: Basic designation indicating a 25mm bore, 47mm OD, and 12mm width.
- AC: Angular Contact design.
- D: Specific internal design and contact angle (25°).
- T: Phenolic (synthetic resin) cage material.
- P: Indicates the bearing is supplied with a preload.
- P4B: The tolerance class is P4 (ABEC-7), with "B" potentially indicating specific internal clearance or fitting practice.
S7005 ACDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row angular contact design, combined with a P4 precision class and factory-set preload, provides high system rigidity, reduces deflection under load, and ensures exceptional running accuracy.
- Optimized Load Capacity: With a 25° contact angle, this bearing is engineered to support significant combined radial and axial loads efficiently.
- Superior High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 34,000 rpm. The lubrication is optimized for these demanding conditions.
- Durability and Reliability: Constructed from chrome steel for both rings and balls, the bearing offers high fatigue life and wear resistance, suitable for a wide operating temperature range.
S7005 ACDTP/P4B Bearing Typical Application Areas
This high-precision bearing is ideally suited for:
- Machine Tool Spindles (High-speed machining centers, grinding spindles)
- Precision Rotary Systems
- High-Frequency Motors
- Medical and Dental Equipment Spindles
- Aerospace Instrumentation
