S7015 CE/HCP4A Bearing Product Overview & Core Advantages
The S7015 CE/HCP4A is a high-precision angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and high-speed capability. This single-row bearing features a 15° contact angle and is supplied with a preload, delivering superior rigidity and precise running accuracy. Manufactured to P4 (ABEC-7) tolerance and incorporating ceramic balls and a phenolic cage, it is ideally suited for machine tool spindles and other high-performance machinery where reliability and speed are critical.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S7015 | Basic bearing series and size designation (75mm bore, 115mm OD, 20mm width). |
| CE | Indicates the use of Hybrid Ceramic balls (Silicon Nitride), which reduce centrifugal forces, lower operating temperatures, and enable higher limiting speeds. |
| HCP4A | A composite code specifying: - HC: Hybrid Ceramic construction. - P4: P4 (ABEC-7) precision tolerance class for minimal runout and vibration. - A: Denotes a specific contact angle of 15° and a light preload grade for optimal stiffness. |
S7015 CE/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of steel rings and ceramic balls significantly reduces weight and inertial forces, leading to lower friction, reduced heat generation, and a substantially higher limiting speed (19,000 rpm) compared to all-steel equivalents.
- High Rigidity & Precision: The 15° contact angle and applied preload work in unison to provide high axial and radial stiffness, ensuring minimal deflection under load and exceptional positional accuracy for the spindle.
- Optimized for High Speeds: The lightweight phenolic resin cage is engineered for high-speed operation, offering excellent strength-to-weight ratio and smooth guidance of the ceramic balls.
- Superior Load Capacity: With a dynamic load rating of 5850 lbf and a static load rating of 4860 lbf, this bearing reliably handles combined radial and axial loads in high-demand applications.
- Sealed & Lubricated: The bearing is sealed and comes pre-lubricated, protecting against contamination and providing long-term, maintenance-free operation within its specified temperature range.
S7015 CE/HCP4A Bearing Typical Application Areas
