S71907 CE/HCP4ADT Bearing Product Overview & Core Advantages
The S71907 CE/HCP4ADT is a precision angular contact ball bearing designed for demanding applications requiring exceptional performance. This duplex tandem (DT) arrangement bearing set offers superior high rigidity and is optimized for handling combined loads. Manufactured to ABEC 7 / P4A tolerance class, it features ceramic balls and a phenolic cage, enabling outstanding high-speed performance and extended service life. Its sealed design with pre-applied grease ensures reliable, long-term operation in precision machinery.
S71907 CE/HCP4ADT Bearing Model Code Explained, Specifications & Naming Convention
The model number S71907 CE/HCP4ADT is decoded as follows:
- S7: High-precision bearing series
- 1907: Standard size designation (35mm bore, 55mm OD, 20mm width)
- CE: Ceramic balls (typically Silicon Nitride, Si3N4)
- HC: Phenolic resin cage
- P4A: High precision tolerance class (superior to ABEC 7)
- DT: Duplex Tandem arrangement (two bearings matched for increased axial load capacity in one direction)
S71907 CE/HCP4ADT Bearing Structural Features & Performance Benefits
- Superior Rigidity & Load Capacity: The duplex tandem (DT) matched arrangement of two bearings provides significantly increased axial stiffness and load-carrying capacity in one direction, making it ideal for applications with heavy thrust loads.
- Enhanced High-Speed Performance: The combination of ceramic balls (lower density, reduced centrifugal force) and a lightweight phenolic cage allows for a very high limiting speed of 56,000 rpm, reducing friction and heat generation.
- Precision & Accuracy: Manufactured to P4A tolerance class with a 15° contact angle, this bearing ensures minimal runout and high rotational accuracy for precise positioning systems.
- Sealed & Pre-Lubricated: The sealed design protects against contamination, and the factory-applied grease lubrication provides maintenance-free operation within the specified temperature range of -30°C to 110°C.
S71907 CE/HCP4ADT Bearing Typical Application Areas
This high-performance bearing is engineered for advanced applications where precision, speed, and reliability are critical. Key industries and equipment include:
- High-Frequency CNC Spindles: For machining centers and precision grinders.
- High-Speed Electric Motors: Especially in aerospace and robotics.
- Precision Instrumentation: Medical devices, optical scanners, and coordinate measuring machines.
- Advanced Pump & Compressor Systems: Where high rotational speeds and reliability are required.
