71913 ACEGA/P4A Bearing Product Overview & Core Advantages
The 71913 ACEGA/P4A is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. This single bearing features an Extra light preload (Class A) and is manufactured to P4A tolerance class, ensuring superior running precision. Its key advantage lies in its ability to handle high-speed operations with a limiting speed of 36,000 rpm, making it an ideal high-speed bearing for demanding machinery. The universal matchable (SU) design allows for simplified mounting in pairs to support combined loads effectively.
71913 ACEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
- 71913: Basic model number denoting a metric, angular contact bearing with 65mm bore, 90mm OD, and 13mm width.
- AC: Angular Contact design with a 25° contact angle.
- E: Optimized internal design for high performance.
- GA: Indicates a Universal Matchable (SU) bearing with Extra light preload (Class A).
- P4A: The tolerance class, signifying very high dimensional and running accuracy.
71913 ACEGA/P4A Bearing Structural Features & Performance Benefits
High Precision & Rigidity: Manufactured to P4A tolerance class with strict dimensional controls (bore/OD tolerance: -0.004mm to 0), this bearing provides exceptional running accuracy and system rigidity. The phenolic cage contributes to smooth operation at high speeds.
Optimized for High-Speed Applications: With a limiting speed of 36,000 rpm, the bearing is engineered for high-speed spindles. The 25° contact angle provides an excellent balance between radial and axial load capacity.
Superior Load Capacity: The robust chrome steel construction enables a dynamic load rating of 3510 lbf and a static load rating of 2610 lbf, ensuring reliable performance under demanding operating conditions.
Universal Matching Capability: Designed as Universal Matchable (SU), these bearings can be easily paired in a back-to-back or face-to-face arrangement without selective mounting, simplifying installation and ensuring optimal preload.
