K19013AR0 Bearing Product Overview & Core Advantages
The K19013AR0 is a metric thin-section angular contact ball bearing engineered for applications requiring high precision and space optimization. As part of the Reali-Slim series, this single-row bearing features a 30° contact angle, making it exceptionally capable of handling combined radial and axial loads simultaneously. Its compact cross-section (13mm width) relative to its bore (190mm) provides a significant design advantage in lightweight, high-rigidity assemblies. Manufactured to ABEC-1 precision standards, it delivers reliable performance in demanding operational environments.
K19013AR0 Bearing Model Code Explained, Specifications & Naming Convention
The model number K19013AR0 is decoded as follows:
- K: Identifies the bearing as part of the Kaydon® Reali-Slim product line.
- 190: Indicates the bore diameter in millimeters (190 mm).
- 13: Specifies the cross-section width in millimeters (13 mm).
- A: Denotes the angular contact design with a 30° contact angle.
- R0: Specifies the internal radial clearance group (0.0000 – 0.0005").
K19013AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides excellent resistance to combined loads. It offers a substantial radial dynamic load rating of 3135 lbf and a high axial static load rating of 7581 lbf.
- Precision Engineering: Built to ABEC-1 tolerance class with a tightly controlled radial internal clearance, ensuring smooth, precise operation and minimal runout.
- Premium Material Construction: The rings and balls are made from chrome steel for high durability and wear resistance. The brass cage ensures stable ball guidance and is suitable for a wide range of operating conditions.
- Optimized for Thin-Section Applications: The design minimizes cross-sectional width without compromising on load capacity, making it ideal for compact, weight-sensitive machinery.
K19013AR0 Bearing Typical Application Areas
This bearing is ideally suited for applications where space and weight are at a premium, and precise rotational motion is critical. Key industries and equipment include:
- Robotics and Automation: Joint and actuator bearings in robotic arms.
- Aerospace & Defense: Gimbals, control mechanisms, and radar systems.
- Medical Equipment: High-precision scanners, surgical robots, and imaging devices.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical and Instrumentation Systems: Rotary tables and positioning devices.
