7036 ACD/P4AQBCC Bearing Product Overview & Core Advantages
The 7036 ACD/P4AQBCC is a precision quadruplex matched set of angular contact ball bearings designed for the most demanding applications. Its primary advantage lies in the Quadruplex Back-to-Back (QBC) arrangement, which provides exceptional rigidity and the ability to withstand complex combined loads, including significant radial and axial forces. Manufactured to the stringent P4A tolerance class, this bearing set ensures high running accuracy and reliability, making it ideal for high-precision machinery requiring superior stiffness and load capacity in a compact footprint.
7036 ACD/P4AQBCC Bearing Model Code Explained, Specifications & Naming Convention
- 7036: Basic designation indicating a 180mm bore and 280mm outside diameter.
- A: Denotes a 25° contact angle, optimized for carrying high axial loads.
- CD: Signifies a Moderate preload (Class C) applied to the bearing set.
- P4A: Indicates a high precision tolerance class exceeding standard P4 levels, ensuring ultra-precise rotational accuracy.
- QBCC: Specifies the matched arrangement as a Quadruplex (4 bearings) Back-to-Back (QBC) set. The final "C" confirms the preload class (C).
7036 ACD/P4AQBCC Bearing Structural Features & Performance Benefits
Unmatched Rigidity and Load Capacity: The Quadruplex Back-to-Back (QBC) configuration creates an extremely stiff bearing system, effectively resisting moment loads and providing stable support for spindles and shafts. This design significantly enhances the system's dynamic and static load ratings (136,125 lbf dynamic / 247,500 lbf static).
Optimized for Precision and Speed: The 25° contact angle is ideal for handling substantial axial loads. The phenolic resin cage contributes to smooth operation at high speeds, supporting a limiting speed of 16,250 rpm. The P4A precision grade guarantees minimal runout and vibration for superior performance.
Superior Material Construction: Manufactured from chrome steel for both rings and balls, the bearing offers high durability and fatigue resistance. The set is supplied lubricated and ready for installation, operating effectively within a temperature range of -30°C to 110°C.
7036 ACD/P4AQBCC Bearing Typical Application Areas
This high-precision, high-rigidity bearing set is specifically engineered for advanced machinery where accuracy and stiffness are paramount. Typical applications include:
- High-Precision Machine Tool Spindles
- High-Speed Machining Centers
- Precision Grinding Spindles
- Aerospace and Defense Positioning Systems
- Advanced Robotics and Automation Equipment
