KC045CP6 Bearing Product Overview & Core Advantages
The KC045CP6 is a high-precision thin section bearing engineered for applications demanding compact design and superior performance. As a Reali-Slim Open Bearing with a single row construction, it is optimized for radial loads and is manufactured to an exacting ABEC 7F tolerance class. Its large 4.5" bore within a minimal 0.375" cross-section makes it ideal for saving space and weight in sophisticated machinery without compromising on load capacity or precision.
KC045CP6 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Significance |
|---|---|---|
| KC045 | Bore Size: 4.5 Inch | Specifies the large internal diameter of the bearing. |
| C | Cross-Section: 0.187" (C-Series) | Indicates a specific, ultra-thin radial cross-section for maximum space savings. |
| P6 | Precision Class (Equivalent to ABEC 7F) | Denotes a very high level of dimensional and running accuracy, ensuring smooth, low-vibration operation. |
KC045CP6 Bearing Structural Features & Performance Benefits
- Thin-Section Design: The C-series cross-section provides a significantly reduced weight and envelope, enabling compact and lightweight assemblies in robotics, aerospace, and medical equipment.
- High Precision & Rigidity: Manufactured to ABEC 7F standards with a brass cage, this bearing offers exceptional running accuracy and stability, minimizing system vibration and error.
- Robust Load Capacity: With a dynamic load rating of 1143 lbf and a static load rating of 2340 lbf, it reliably handles substantial radial loads despite its slim profile.
- Optimized Material Selection: The use of chrome steel for both rings and balls ensures high durability, wear resistance, and a long operational life.
- Pre-Lubricated & Ready-to-Use: The bearing comes pre-lubricated, simplifying installation and providing immediate, reliable performance within its specified temperature range.
KC045CP6 Bearing Typical Application Areas
The KC045CP6 is ideally suited for high-performance applications where space, weight, and precision are critical. Key industries and equipment include:
- Robotics: Rotary joints, actuator arms, and precision gearing systems.
- Aerospace & Defense: Guidance systems, gimbals, and radar apparatus.
- Medical Equipment: MRI and CT scanners, surgical robots, and diagnostic instruments.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical and Instrumentation Systems: High-accuracy rotary tables and scanning devices.
