S71913 ACB/HCP4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness and enables the bearing to handle substantial combined radial and axial loads from both directions, making it suitable for applications with complex loading conditions.
High-Speed Performance: The combination of a lightweight phenolic cage and ceramic balls significantly reduces centrifugal forces, enabling a high limiting speed of 31,000 rpm. This makes it an excellent high-speed bearing for precision spindles.
Precision & Longevity: Manufactured to a P4A tolerance class with a 25° contact angle, this bearing guarantees exceptional running accuracy and smooth operation. The integral seals and pre-applied grease provide effective contamination protection and contribute to a long, maintenance-free service life within the specified temperature range.
S71913 ACB/HCP4ADGA Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles (High-speed machining centers, grinding spindles)
- Precision Instrumentation
- High-Frequency Motors
- Medical Equipment (e.g., Dental handpieces)
- Aerospace Actuation Systems
