KC090AR0 Bearing Product Overview & Core Advantages
The KC090AR0 is a high-performance thin-section angular contact ball bearing designed for applications requiring exceptional precision and space optimization. As part of the Reali-Slim Open Bearings series with an inch system of measurement, it features a single-row construction and is engineered to handle significant combined loads, including radial and axial loads in one direction. Its compact cross-section, with a width of only 0.375", makes it ideal for high-rigidity applications where space constraints and weight reduction are critical, such as robotics, aerospace components, and precision medical equipment.
KC090AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KC090 | Indicates the specific bearing series and size (9" bore, 9.75" OD). |
| A | Signifies the 30° contact angle, optimized for handling high axial loads. |
| R0 | Denotes a standard radial internal clearance (0.0000 – 0.0005"). |
| Open | Specifies an unsealed (Open) design, allowing for custom lubrication schemes and high-speed operation. |
KC090AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides high rigidity and enables the bearing to support substantial combined radial and axial loads. It boasts a high radial static load rating of 5520 lbf and an axial static load rating of 4630 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight bore and outside diameter tolerances, ensuring smooth operation and high positional accuracy in precision assemblies.
- Optimized Material Selection: Components made from Chrome Steel (rings and balls) and a Brass cage offer excellent durability, wear resistance, and stability for long service life.
- Space-Saving Design: As a thin-section bearing, it provides a large bore diameter relative to its cross-section, maximizing design flexibility in compact machinery.
KC090AR0 Bearing Typical Application Areas
The KC090AR0 is ideally suited for demanding applications across various industries, including:
- Robotics: Rotary joints and arm actuators requiring high precision and rigidity.
- Aerospace & Defense: Guidance systems, radar platforms, and actuation mechanisms.
- Medical Equipment: CT scanners, surgical robots, and other high-precision diagnostic devices.
- Semiconductor Manufacturing: Wafer handling robots and precision positioning stages.
- Industrial Automation: Rotary tables, indexing heads, and other precision motion control systems.
