7036 CD/P4A Bearing Product Overview & Core Advantages
The 7036 CD/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This single-row bearing features a 15° contact angle and is supplied with a preload, making it ideal for supporting combined loads where high axial and radial stiffness is critical. Manufactured to the stringent P4 (ABEC-7) tolerance class, it ensures smooth, quiet operation and is pre-lubricated for immediate use in high-speed spindles and other precision machinery.

| /P4A | Specifies the P4 tolerance class (ABEC-7), denoting very high running accuracy. |
7036 CD/P4A Bearing Structural Features & Performance Benefits
High Rigidity and Precision: The combination of a 15° contact angle and an applied preload provides superior axial and radial stiffness, minimizing deflection under load and ensuring precise shaft positioning. The P4 tolerance class guarantees minimal runout for smooth, high-accuracy rotation.
Optimized Load Capacity: The angular contact design is engineered to support significant combined loads (simultaneous radial and axial forces). With a high dynamic load rating of 54,450 lbf, it offers excellent longevity in demanding applications.
High-Speed Capability: The lightweight phenolic resin cage ensures stable operation and reduced centrifugal forces, contributing to a high limiting speed of 7,500 rpm. The bearing is pre-lubricated to support these high rotational speeds from the moment of installation.
Durable Construction: Manufactured from chrome steel for both rings and balls, this bearing provides high fatigue life and wear resistance, suitable for a wide operating temperature range.
7036 CD/P4A Bearing Typical Application Areas
The 7036 CD/P4A is ideally suited for high-performance machinery where precision and speed are paramount. Key applications include:
- Machine Tool Spindles: For high-speed milling, grinding, and turning centers.
- Precision Grinding Spindles: Where extreme accuracy and minimal vibration are required.
- High-Frequency Motors: Used in spindles for PCB drilling and other high-RPM applications.
- Medical Equipment: Such as high-speed dental handpieces and imaging device rotors.
- Aerospace & Defense Systems: In gyroscopes, radar systems, and other precision instrumentation.
