7036 CD/HCP4A Bearing Product Overview & Core Advantages
The 7036 CD/HCP4A is a high-precision angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and rigidity. This single-row bearing features a 15° contact angle and is supplied with a preload, ensuring minimal axial and radial play for superior system stability. Its construction with a ceramic ball and phenolic cage enables outstanding high-speed performance, with a limiting speed of 9,000 rpm. Designed to handle combined loads, it is an ideal solution for high-rigidity and high-reliability machine tool spindles and precision equipment.
7036 CD/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Indicates a duplex bearing set with a specific preload and mounting arrangement. |
| HC | Signifies the use of Hybrid Ceramic balls (Silicon Nitride), which reduce weight and centrifugal force for higher speeds. |
| P4 | Denotes a high-precision tolerance class (ABEC-7), ensuring extremely tight dimensional and running accuracy. |
| A | Specifies a 30° contact angle (Note: Product data shows 15°, this may indicate a specific internal design variant). |
7036 CD/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The P4 tolerance class and application of preload eliminate internal clearance, providing exceptional stiffness and rotational accuracy critical for machining and positioning applications.
- Superior High-Speed Capability: The combination of ceramic balls and a lightweight phenolic resin cage significantly reduces centrifugal forces and friction, enabling reliable operation at the high limiting speed of 9,000 rpm.
- Excellent Load Capacity: With a dynamic load rating of 54,450 lbf and a static load rating of 65,250 lbf, this bearing is robustly designed to handle significant combined radial and axial loads.
- Optimized for Performance: The open seal type allows for customized lubrication schemes to match specific operational needs, while the chrome steel rings ensure core durability and long service life.
7036 CD/HCP4A Bearing Typical Application Areas
This precision bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and rotary actuators requiring high rigidity and accuracy.
- High-Frequency Motors and Spindles: Applications where minimal runout and high rotational speeds are paramount.
- Medical and Laboratory Equipment: Centrifuges and precision instruments.
