7026 ACDGC/P4A Bearing Product Overview & Core Advantages
The 7026 ACDGC/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to accommodate combined loads (radial and axial loads in one direction), this bearing features a 25° contact angle and P4A super-precision tolerance class, making it ideal for machine tool spindles and other demanding equipment. Its universal matching capability (SU) allows for flexible mounting arrangements in sets of three to optimize preload and system performance.
Model Code Detailed Explanation
| Code Segment | Technical Meaning |
| 7026 | Basic bearing designation (130mm bore, 200mm OD) |
| AC | Angular Contact design |
| DGC | Moderate preload (Class C) |
| P4A | Super precision tolerance class |
7026 ACDGC/P4A Bearing Structural Features & Performance Benefits
High Precision Construction: The P4A tolerance class ensures minimal runout and superior rotational accuracy, critical for high-speed applications up to 11,000 rpm.
Optimized Load Capacity: With a 25° contact angle and robust chrome steel construction, this bearing delivers excellent performance under combined radial and axial loads (dynamic load rating: 31,500 lbf).
Enhanced High-Speed Performance: The phenolic resin cage provides excellent strength-to-weight ratio, reducing centrifugal forces and enabling stable operation at high rotational speeds.
Universal Matching Capability: Designed as Universal Matchable (SU), these bearings can be mounted in sets of three with controlled preload, delivering superior system rigidity and accuracy.
