S7006 CE/HCP4A Bearing Product Overview & Core Advantages
The S7006 CE/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. This single-row bearing is distinguished by its P4 (ABEC-7) tolerance class and ceramic ball construction, enabling superior high-speed operation and extended service life. Its design is optimized to handle combined loads, offering high rigidity and reliable performance in precision machinery. The bearing comes prelubricated and sealed, making it a ready-to-install, high-reliability component for critical systems.
S7006 CE/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
The model number S7006 CE/HCP4A provides specific technical details:
- S7006: Denotes the basic bearing series and size (30mm bore, 55mm OD, 13mm width).
- C: Indicates a 15° contact angle, optimized for high-speed applications with moderate axial load capacity.
- E: Signifies a high-precision P4 tolerance class (ABEC-7).
- HC: Stands for Hybrid Ceramic, specifying that the rolling elements are ceramic balls.
- P4A: Confirms the P4 precision grade and specific internal clearance/geometry optimizations.
S7006 CE/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The use of ceramic balls with a steel ring significantly reduces centrifugal forces, lowers operating temperature, and provides excellent electrical insulation, contributing to a higher limiting speed of 47,000 rpm.
- High Rigidity & Precision: Manufactured to a P4 tolerance class with a 15° contact angle, this bearing delivers high running accuracy and stiffness, essential for precise shaft positioning and reduced vibration.
- Superior Load Capacity: Engineered to support substantial combined (radial and axial) loads, with a dynamic load rating of 2106 lbf and a static load rating of 1170 lbf.
- Optimized for High-Speed: The phenolic resin cage is lightweight and robust, ideal for high-speed operation, while the pre-applied lubrication ensures consistent performance across the operating temperature range of -30°C to 110°C.
- Sealed & Prelubricated: The integral seals protect against contamination and retain lubricant, offering a maintenance-free, long-service-life solution.
S7006 CE/HCP4A Bearing Typical Application Areas
