S7001 CE/HCP4A Bearing Product Overview & Core Advantages
The S7001 CE/HCP4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and reliability. This single-row bearing features a 15° contact angle, enabling it to support combined radial and axial loads simultaneously. Manufactured to P4 (ABEC-7) tolerance class, it guarantees ultra-precise running characteristics. Its compact design, with a 12 mm bore and 8 mm width, makes it ideal for space-constrained, high-speed machinery. The combination of a phenolic cage and ceramic balls significantly enhances its high-speed performance and service life.
S7001 CE/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CE | Hybrid Ceramic Balls | Reduced weight, lower friction, higher limiting speed, and extended lubrication life. |
| HC | Phenolic (Polyamide) Cage | Excellent strength-to-weight ratio, reduced friction, and superior performance at high speeds. |
| P4A | P4 (ABEC-7) Tolerance Class | Guarantees ultra-high running accuracy, low noise, and minimal vibration for precision applications. |
S7001 CE/HCP4A Bearing Structural Features & Performance Benefits
- High-Speed Capability: The lightweight phenolic cage and ceramic balls (CE) drastically reduce centrifugal forces, enabling the bearing to achieve an exceptional limiting speed of 98,000 rpm. This makes it a premier choice for high-speed spindles.
- High Rigidity and Load Capacity: The optimized 15° contact angle provides excellent resistance to combined loads, offering reliable performance under both radial and one-directional axial forces.
- Pre-optimized Performance: The bearing is supplied with preload, which eliminates internal clearance. This results in greater shaft rigidity, precise rotational accuracy, and reduced noise and vibration levels.
- Long-Term Reliability: The bearing comes pre-lubricated with high-quality grease suitable for its specified temperature range (-30°C to 110°C), ensuring immediate operation and long-term, maintenance-free performance in sealed environments.
S7001 CE/HCP4A Bearing Typical Application Areas
