KB110AR0 Bearing Product Overview & Core Advantages
The KB110AR0 is a high-precision thin section angular contact ball bearing designed for applications demanding exceptional rigidity and precise motion control. As part of the Reali-Slim® Open series with inch measurements, it excels in handling combined loads, simultaneously supporting significant radial and axial forces. Its compact cross-section and 30° contact angle make it ideal for space-constrained, high-accuracy systems requiring reliable performance under complex loading conditions.
KB110AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KB110 | Indicates the bearing series and nominal bore diameter of 11 inches. |
| A | Signifies the 30° contact angle, optimized for high axial load capacity. |
| R0 | Denotes a standard radial internal clearance and ABEC-1 tolerance class. |
| Open (from spec) | No seals or shields, allowing for higher speeds and custom lubrication schemes. |
KB110AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design with a 30° contact angle provides superior resistance to combined loads, offering a radial dynamic load rating of 1540 lbf and a substantial axial static load rating of 4000 lbf.
- Precision Engineering: Manufactured to ABEC-1 precision tolerances, this bearing ensures smooth, accurate rotation, which is critical for high-performance applications.
- Optimized Material Selection: The chrome steel rings and balls, combined with a brass cage, provide excellent durability, wear resistance, and stable operation at high speeds.
- Thin-Section Design: With a compact cross-section (Width: 0.3125"), it enables lightweight and space-saving designs without compromising on performance or load moment capacity (Static load moment: 15440 lbf).
KB110AR0 Bearing Typical Application Areas
This bearing is ideally suited for precision machinery and systems where a large bore, compact cross-section, and high load capacity are required. Key applications include:
- Robotics: Robot arm joints and precision actuators.
- Aerospace & Defense: Gimbals, radar platforms, and guidance systems.
- Medical Equipment: CT scanners, MRI machines, and surgical robots.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Automation: Rotary tables, indexing heads, and high-precision spindles.
