7036 CD/P4ATBTA Bearing Product Overview & Core Advantages
The 7036 CD/P4ATBTA is a precision angular contact ball bearing designed for the most demanding applications. Engineered as a triplex back-to-back (TBT) matched set, this configuration delivers exceptional system rigidity and stability under complex loading conditions. Operating within a P4A tolerance class, it guarantees ultra-high running accuracy, making it ideal for high-speed spindles and precision machinery where minimal runout and superior positional accuracy are critical. Its extra light preload (Class A) ensures smooth, quiet operation from startup, reducing vibration and enhancing overall machine performance.
7036 CD/P4ATBTA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7036 | Basic bearing series and size designation (180mm bore, 280mm OD). |
| CD | Indicates a 15° contact angle, optimized for carrying combined radial and axial loads. |
| P4A | Specifies the tolerance class, denoting ultra-precision dimensions and running accuracy. |
| TBT | Denotes the Triplex Back-to-Back matched arrangement of three bearings. |
| A | Specifies an Extra Light Preload (Class A) for minimal friction and high-speed capability. |
7036 CD/P4ATBTA Bearing Structural Features & Performance Benefits
Unmatched Rigidity and Load Capacity: The triplex back-to-back (TBT) arrangement creates an extremely stiff bearing system, capable of withstanding heavy combined loads (radial and axial) and significant overturning moments. This configuration provides superior shaft positioning and resistance to deflection under load.
High-Speed Performance: The phenolic resin cage offers excellent strength-to-weight ratio, reducing centrifugal forces and allowing for a limiting speed of 16,250 rpm. The 15° contact angle is ideally suited for high-speed applications where axial loads are present.
Precision and Longevity: Manufactured to P4A tolerance class from high-grade chrome steel, this bearing ensures minimal vibration and extended service life. The bearings are supplied lubricated and ready for installation, operating effectively within a temperature range of -30°C to 110°C.
7036 CD/P4ATBTA Bearing Typical Application Areas
The 7036 CD/P4ATBTA is engineered for high-performance applications requiring maximum precision and rigidity, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Rotary Tables: Indexing and positioning systems.
- Aerospace & Defense Systems: Gyroscopes, radar platforms, and other critical rotating assemblies.
- High-Frequency Motors and Spindles: Where extreme rotational accuracy and stiffness are non-negotiable.
