7036 ACDGC/P4A Bearing Product Overview & Core Advantages
The 7036 ACDGC/P4A is a single row angular contact ball bearing designed for applications demanding high precision and superior running accuracy. As a Universal Matchable (SU) bearing, it is supplied in sets of three for precise preload control when mounted in pairs. Its key advantages include a 25° contact angle for excellent axial load capacity, a P4A tolerance class for exceptional dimensional and running accuracy, and a phenolic resin cage enabling high-speed operation. This bearing is pre-lubricated and optimized to handle combined radial and axial loads simultaneously in high-performance machinery.

| 7036 | Basic Bearing Size Designation | Indicates a 180mm bore, 280mm OD, and 46mm width. |
| AC | Angular Contact Design | Optimized geometry for combined loads. |
| DGC | Contact Angle & Cage Material | Denotes a 25° contact angle and a phenolic resin cage. |
| P4A | Tolerance Class | Specifies a very high precision grade for dimensional and running accuracy, tighter than ABEC 7. |
7036 ACDGC/P4A Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 25° contact angle is engineered to provide an optimal balance between radial and axial load carrying capacity, making it ideal for applications with significant thrust loads.
High-Speed Phenolic Cage: The lightweight and robust phenolic resin cage ensures stable operation at the high limiting speed of 16,250 rpm, reducing centrifugal forces and friction.
Superior Precision (P4A Grade): Manufactured to P4A tolerance class, this bearing guarantees minimal runout and vibration, which is critical for the accuracy and surface finish in precision machinery.
Universal Matching (SU): Supplied as a universal matchable set of three bearings allows for flexible mounting configurations (back-to-back, face-to-face, or tandem) to achieve a defined moderate preload (Class C), enhancing system rigidity and rotational accuracy.
High Load Ratings: With a dynamic load rating of 51,525 lbf and a static load rating of 61,875 lbf, it offers reliable performance under demanding operating conditions.
