S71913 ACB/HCP4A Bearing Product Overview & Core Advantages
The S71913 ACB/HCP4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. Engineered to a P4 (ABEC-7) tolerance class, it offers superior running accuracy. Its key advantage lies in its ability to accommodate combined loads, simultaneously handling significant radial and axial loads. The use of ceramic balls and a phenolic cage contributes to high-speed capability, reduced weight, and extended service life, making it an ideal choice for high-reliability, high-rigidity systems.
Model Code Breakdown
- S71913: Denotes the bearing series and size designation (65mm bore, 90mm OD, 13mm width).
- ACB: Indicates a 25° contact angle and a specific internal design optimized for high rigidity and precise operation.
- HCP4A: Specifies the P4 tolerance class (ABEC-7) and signifies that the bearing is supplied preloaded for immediate high-stiffness performance.
S71913 ACB/HCP4A Bearing Structural Features & Performance Benefits
High Rigidity and Precision: Manufactured to P4 tolerance standards, this bearing ensures minimal runout and vibration, which is critical for high-precision applications. The specified preload further enhances system stiffness and positional accuracy.
Superior Load Capacity: With a 25° contact angle, the S71913 ACB/HCP4A is engineered to handle substantial combined (radial and axial) loads efficiently.
High-Speed Performance: The combination of ceramic balls, which are lighter and harder than steel, and a lightweight phenolic resin cage allows for a high limiting speed, reducing centrifugal forces and operational temperature.
Optimized for Demanding Environments: The bearing comes pre-lubricated and is capable of operating within a temperature range of -30°C to 110°C, ensuring reliable performance under various conditions.
S71913 ACB/HCP4A Bearing Typical Application Areas
