KA045CP0 Bearing Product Overview & Core Advantages
The KA045CP0 is a thin-section open bearing from the Reali-Slim series, engineered for applications demanding space and weight savings without compromising performance. As a single-row ball bearing with an open design, it is optimized for radial loads and offers a compact cross-section. Its inch dimensions (4.5" bore, 5" OD, 0.25" width) make it ideal for replacing custom-machined bushings in precision assemblies. The bearing features a brass cage for stable operation and is pre-lubricated for immediate use, providing a reliable solution for high-precision, low-friction applications.
KA045CP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KA045 | Indicates the specific bearing size with a 4.5" bore diameter. |
| C | Denotes the radial internal clearance group. |
| P0 (Implied by ABEC-1) | Specifies the tolerance class per ISO standards, equivalent to ABEC-1, ensuring standard precision for smooth operation. |
| Open (No Seal) | Signifies an open bearing design, allowing for custom lubrication schemes and maximum speed capability in clean environments. |
KA045CP0 Bearing Structural Features & Performance Benefits
Thin-Section Design: The KA045CP0 features a consistent cross-section (0.25" width) across its bore sizes, enabling significant weight reduction (0.22 lbs) and space savings in compact machinery. This design minimizes inertia and allows for more efficient system layouts.
High Load Capacity & Rigidity: Manufactured from chrome steel for both rings and balls, this bearing delivers a radial dynamic load rating of 610 lbf and a radial static load rating of 1440 lbf. The single-row construction provides reliable support for radial loads in precision applications.
Precision & Smooth Operation: With an ABEC-1 precision class and a controlled radial internal clearance (0.0000 – 0.0005"), the bearing ensures low noise and vibration. The brass cage enhances operational stability and is suitable for a wide temperature range from -30°C to 110°C.
Versatile Lubrication: The open structure permits the use of various lubricants tailored to specific application needs, optimizing performance for speed, load, and environmental conditions.
KA045CP0 Bearing Typical Application Areas
The KA045CP0 thin-section bearing is ideally suited for applications where space constraints and weight minimization are critical. Common uses include:
- Robotics and automation arms
- Aerospace control mechanisms and actuators
- Medical equipment such as scanners and surgical devices
- Semiconductor manufacturing equipment
- Precision rotary tables and indexing systems
