S71912 ACE/HCP4ADGA Bearing Product Overview & Core Advantages
The S71912 ACE/HCP4ADGA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This sealed bearing features a universal matchable (SU) design, allowing two bearings to be paired in a back-to-back or face-to-face arrangement to optimize performance for specific load conditions. Its core advantages include the ability to handle combined loads (radial and axial) simultaneously, superior high-speed capability facilitated by its phenolic cage and ceramic balls, and long service life due to its pre-lubrication and sealed construction. Engineered to P4A tolerance with an extra light preload, it delivers the high rigidity and rotational accuracy essential for advanced machinery.
Model Code Breakdown
- S7: High Precision / High Speed Series
- 1912: Standardized Size Code (Bore: 60mm, OD: 85mm, Width: 26mm)
- ACE: Contact Angle of 25°, Universal Matchable (SU) design
- HC: Hybrid Ceramic (Steel rings with Ceramic balls)
- P4A: Tolerance class P4A (exceeds ABEC 7 precision)
- DGA: Sealed on both sides, pre-lubricated with grease
S71912 ACE/HCP4ADGA Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The angular contact design with a 25° contact angle and the option for a universal matched set provides high rigidity, enabling the bearing to withstand significant combined radial and axial loads.
Superior High-Speed Performance: The combination of lightweight phenolic resin cage and low-density, hard ceramic balls reduces centrifugal forces and friction, allowing for a very high limiting speed of 32,500 rpm. This makes it an ideal high-speed bearing.
Extended Service Life and Reliability: The standard sealed construction with pre-applied grease lubrication protects against contamination and retains lubricant, resulting in a maintenance-free, long-lasting solution suitable for a wide temperature range from -30°C to 110°C.
