KB060AR0 Bearing Product Overview & Core Advantages
The KB060AR0 is a high-precision thin section angular contact ball bearing engineered for applications demanding exceptional rigidity and accuracy within a compact envelope. As part of the Reali-Slim Open Bearings series, this single-row bearing is designed to handle significant combined loads, efficiently supporting both radial and axial forces. Its inch-dimension design, featuring a large 6" bore in a remarkably slim cross-section, makes it an ideal solution for space-constrained, high-performance machinery requiring high rigidity and precise rotational motion.
KB060AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KB | Indicates the Kaydon® Reali-Slim bearing series |
| 060 | Specifies the cross-section series (in this case, a 0.3125" width) |
| A | Denotes a 30° contact angle, optimized for handling substantial axial loads |
| R | Signifies a brass cage (retainer) for enhanced stability and performance |
| 0 | Indicates the bearing is supplied lubricated and ready for operation |
KB060AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design, combined with a 30° contact angle and a robust brass cage, provides exceptional stiffness. This enables the bearing to support high radial dynamic load ratings of 1088 lbf and significant axial static load ratings of 2710 lbf, making it suitable for applications with demanding combined loads.
- Precision & Accuracy: Manufactured to ABEC-1 tolerance standards with tight dimensional control on bore, outside diameter, and width, this bearing ensures smooth, precise, and repeatable operation in high-accuracy systems.
- Optimized Thin-Section Design: The bearing's large 6" bore and minimal 0.3125" cross-section maximize space utilization and reduce system weight (only 0.44 lbs), which is critical in robotics, aerospace, and semiconductor equipment.
- Material & Construction: Components made from Chrome Steel provide high strength and durability, while the brass cage ensures reliable performance at moderate speeds and in varied operating conditions.
KB060AR0 Bearing Typical Application Areas
- Robotics: Rotary joints, robot arms, and precision actuators where high rigidity and compact design are paramount.
- Aerospace & Defense: Gimbals, radar systems, and control surface actuators requiring lightweight, high-precision components.
- Semiconductor Manufacturing: Wafer handling robots, precision stages, and other equipment where accuracy and minimal deflection are critical.
- Medical Equipment: CT scanners, MRI systems, and surgical robots that demand reliable, smooth motion in a confined space.
- Industrial Automation: Rotary tables, indexing heads, and other precision machinery utilizing large-bore, thin-section ball bearings.
