KF200AR0 Bearing Product Overview & Core Advantages
The KF200AR0 is a thin-section angular contact ball bearing designed for applications requiring high precision and space optimization. As part of the Reali-Slim Open Bearings series with a single row construction, it excels in handling combined loads—simultaneously supporting significant radial loads and thrust loads in one direction due to its 30° contact angle. Manufactured to ABEC-1 precision tolerances, this bearing is ideal for compact, high-rigidity assemblies where weight reduction and precise motion control are critical.
KF200AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KF200 | Indicates the specific bearing series and size designation within the Reali-Slim product line. |
| A | Signifies the 30° contact angle, optimized for high thrust load capacity. |
| R0 | Denotes Radial Internal Clearance of 0.0000 – 0.0005", suitable for precision applications requiring minimal play. |
KF200AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design with a 30° contact angle provides high axial and radial stiffness, enabling it to handle a radial dynamic load rating of 8562 lbf and a static load moment of 81120 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight bore and outside diameter tolerances (-0.0018"– 0"), ensuring consistent performance and ease of installation in high-precision machinery.
- Premium Materials: Components made from Chrome Steel (rings and balls) and a Brass cage offer excellent durability, corrosion resistance, and smooth operation under high-speed conditions.
- Space-Saving Design: With a cross-section of only 0.75" width and large 20" bore, this thin-section bearing maximizes space efficiency without compromising performance.
KF200AR0 Bearing Typical Application Areas
The KF200AR0 is engineered for demanding applications where precision, compactness, and high load capacity are essential. Key industries and equipment include:
- Robotics and Automation: Robot arm joints, rotary actuators, and precision positioning systems.
- Aerospace & Defense: Guidance systems, radar platforms, and actuator mechanisms.
- Medical Equipment: CT scanners, MRI machines, and surgical robot joints requiring smooth, precise rotation.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Machinery: Rotary tables, indexing heads, and other compact machinery requiring high moment load capacity.
