S7006 CDGB/P4A Bearing Product Overview & Core Advantages
The S7006 CDGB/P4A is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. As a single bearing with Universal Matchable (SU) designation, it can be paired with identical bearings in sets to achieve specific preload and stiffness requirements. Its 15° contact angle and P4A tolerance class make it ideally suited for handling combined loads (radial and axial) simultaneously, offering high rigidity and stable performance in high-speed operational environments up to 100,500 rpm.

S7006 CDGB/P4A Bearing Structural Features & Performance Benefits
High Precision & Rigidity: Manufactured to P4A tolerance class with extremely tight dimensional control, this bearing ensures minimal runout and vibration. The phenolic resin cage provides excellent dimensional stability and reduced friction, contributing to smooth operation at high speeds.
Superior Load Capacity: The 15° contact angle is optimized to handle significant combined radial and axial loads. With a dynamic load rating of 3218 lbf and a static load rating of 1800 lbf, it offers robust performance in demanding applications.
Exceptional High-Speed Performance: The combination of the lightweight phenolic cage, precision-ground chrome steel components, and optimized internal geometry enables a remarkable limiting speed of 100,500 rpm.
Reduced Maintenance & Enhanced Reliability: The sealed design effectively shields the bearing from contaminants and retains the factory-fill grease lubrication. This creates a maintenance-free solution for the designated temperature range of -30°C to 110°C.
S7006 CDGB/P4A Bearing Typical Application Areas
- Machine Tool Spindles: High-speed machining centers, grinding spindles, and CNC lathes.
