KA120CP0 Bearing Product Overview & Core Advantages
The KA120CP0 is a thin-section open bearing from the Reali-Slim series, engineered for applications demanding compact design and high precision in a large bore format. This single-row ball bearing is designed to handle primarily radial loads efficiently. Its standout feature is the extremely slim cross-section relative to its large 12-inch bore, enabling significant space and weight savings in sophisticated machinery. Manufactured to ABEC-1 precision tolerances, it ensures reliable performance and smooth operation, making it an ideal component for high-reliability systems where dimensional constraints are critical.
KA120CP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KA120 | Indicates the specific bearing series (Reali-Slim) and size designation for a 12" bore and a 0.25" width cross-section. |
| C | Specifies the radial internal clearance group. |
| P0 | Denotes a standard ABEC-1 tolerance class, ensuring dimensional accuracy for reliable performance. |
KA120CP0 Bearing Structural Features & Performance Benefits
- Ultra-Thin Section Design: The bearing's 0.25" width relative to its 12" bore is its defining characteristic. This slim profile allows for radical weight reduction and a more compact overall system design without sacrificing a large inner diameter for shaft mounting.
- High-Precision Construction: Built to ABEC-1 standards with tight tolerances on the bore, outside diameter, and width. This ensures precise running accuracy, reduced vibration, and consistent performance.
- Robust Material Composition: The use of Chrome Steel for both rings and balls, combined with a Brass cage, provides excellent durability, wear resistance, and stable operation under load.
- Optimized Load Capacity: Engineered to handle significant radial dynamic loads (1078 lbf) and high radial static loads (3720 lbf), making it suitable for applications with substantial forces.
- Pre-Lubricated for Immediate Use: The bearing comes lubricated from the factory, simplifying installation and providing immediate protection against wear.
KA120CP0 Bearing Typical Application Areas
This bearing is specifically designed for applications where a large shaft diameter must be accommodated within a minimal space envelope. Key industries and equipment include:
- Aerospace & Defense: Gimbals, rotor systems, and radar platforms.
- Robotics: Joints and actuators in robotic arms requiring high precision and a large hollow shaft for wiring.
- Medical Equipment: CT scanners, MRI machines, and surgical robots.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
- Optical and Instrumentation Systems: Rotary tables and positioning devices.
