S7013 ACDGB/P4A Bearing Product Overview & Core Advantages
The S7013 ACDGB/P4A is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Engineered to accommodate combined loads (simultaneous radial and axial loads), this bearing features a 25° contact angle for optimal axial load capacity. Its P4A super-precision tolerance and light preload (Class B) ensure smooth, quiet operation with minimal runout, making it ideal for high-speed spindles and other precision machinery. The phenolic cage and sealed design contribute to its robust performance in demanding environments.

S7013 ACDGB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex back-to-back (DGB) arrangement provides exceptional stiffness, enabling the bearing to handle significant combined radial and axial loads as well as moment loads. The 25° contact angle further enhances axial load carrying capability.
- Super-Precision Performance: Manufactured to P4A tolerance class, this bearing delivers extremely tight dimensional control and minimal runout, essential for high-precision applications requiring smooth rotation and accurate positioning.
- Optimized High-Speed Operation: The phenolic resin cage offers excellent strength-to-weight ratio, reducing centrifugal forces and enabling stable operation at the limiting speed of 31,000 rpm. The light preload (Class B) minimizes friction and heat generation.
- Sealed & Lubricated for Long Life: The sealed design effectively protects against contamination. Pre-greased with high-quality lubricant suitable for a temperature range of -30°C to 110°C, ensuring reliable, long-term performance with minimal maintenance.
