7036 ACD/P4ATBTA Bearing Product Overview & Core Advantages
The 7036 ACD/P4ATBTA is a precision angular contact ball bearing supplied as a triplex back-to-back (TBT) matched set. This configuration is engineered to deliver exceptional system rigidity and superior capacity for handling combined loads (complex radial and axial forces). Manufactured to the exacting P4A tolerance class, it ensures high running accuracy, making it ideal for demanding, high-precision applications requiring maximum stability and performance.
7036 ACD/P4ATBTA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7036 | Basic bearing series, defining the core bearing dimensions: 180mm bore, 280mm outside diameter, 138mm width. |
| ACD | Angular Contact Design with a 25° contact angle, optimized for high axial load capacity. |
| P4A | Indicates a high-precision tolerance class exceeding ABEC 7, ensuring minimal runout and vibration for ultra-precise applications. |
| TB | Specifies the matched arrangement as "Back-to-Back". |
| T | Denotes a triplex set, meaning three bearings are supplied as a pre-matched unit. |
| A | Signifies the preload level is "Extra Light / Class A". |
7036 ACD/P4ATBTA Bearing Structural Features & Performance Benefits
- Exceptional Rigidity and Load Capacity: The triplex back-to-back (TBT) arrangement creates an extremely rigid bearing system, capable of supporting high moment loads and complex combined loads. The 25° contact angle is optimized for significant axial load carrying capability in both directions.
- High-Speed Capability: The lightweight and robust phenolic cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 16,250 rpm, making it suitable for high-speed applications.
- Precision Performance: Conformance to the P4A tolerance class guarantees high dimensional and running accuracy, resulting in reduced vibration, lower noise, and enhanced operational smoothness for precision machinery.
- Durable Construction: Components made from chrome steel (rings and balls) provide high hardness, wear resistance, and a long operational lifespan under demanding conditions.
7036 ACD/P4ATBTA Bearing Typical Application Areas
This high-precision, high-rigidity bearing set is designed for the most demanding industrial applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers where precision and rigidity are paramount.
- Precision Gearboxes: Applications requiring minimal shaft deflection and high positional accuracy.
- Industrial Pumps and Compressors: For handling significant axial and radial loads in high-performance rotating equipment.
- Advanced Robotics and Automation: Critical joints and axes that demand high stiffness and precision.
