S7200 ACD/P4A Bearing Product Overview & Core Advantages
The S7200 ACD/P4A is a single-row angular contact ball bearing designed for applications requiring high precision and matched preload. Engineered to accommodate combined loads, it efficiently handles both radial loads and substantial axial loads in one direction. Its compact design, featuring a 10mm bore and 9mm width, makes it ideal for space-constrained, high-performance assemblies. Manufactured to a P4 (ABEC-7) tolerance class, this bearing delivers exceptional running accuracy and rotational stability, ensuring reliable operation in demanding conditions.
S7200 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7200 ACD | Basic bearing series designation for a 25° contact angle, angular contact bearing. |
| /P4A | Indicates a P4 (ABEC-7) tolerance class and a specific preload rating (A) for high rigidity and precise shaft positioning. |
S7200 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The 25° contact angle and factory-set preload provide high axial and radial stiffness, minimizing deflection under load for superior positioning accuracy.
- Optimized Load Capacity: The single-row design with a high-grade phenolic cage is engineered to support significant combined radial and axial loads simultaneously.
- High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 53,000 rpm.
- Sealed and Lubricated for Life: As a sealed and pre-lubricated unit, it is protected from contamination and is maintenance-free within its specified operating temperature range (-30°C to 110°C).
S7200 ACD/P4A Bearing Typical Application Areas
This precision bearing is ideally suited for:
- High-Speed Machine Tool Spindles
- Precision Grinding Spindles
- High-Frequency Motors
- Medical and Dental Handpieces
- Robotic Drives and Servo Motors
