KD090AR0 Bearing Product Overview & Core Advantages
The KD090AR0 is a high-performance thin-section angular contact ball bearing engineered for applications demanding exceptional precision and space-saving design. This single-row bearing is specifically designed to accommodate combined loads, efficiently handling both radial and substantial axial loads in one direction. Its inch-series dimensions (9" bore, 10" OD, 0.5" width) offer a compact cross-section, making it ideal for high-rigidity support in precision equipment where weight and space are critical constraints. Manufactured to ABEC-1 tolerance standards, it ensures reliable performance and high operational accuracy.
KD090AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KD | Manufacturer series prefix for thin-section bearings. |
| 090 | Indicates a bore diameter of 9 inches. |
| A | Signifies a 30° contact angle, optimized for high axial load capacity. |
| R | Denotes a Reali-Slim open bearing construction. |
| 0 | Specifies the open seal type, allowing for custom lubrication schemes. |
KD090AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: The single-row construction with a minimal cross-section (0.5" width) provides significant weight savings and enables integration into compact assemblies without sacrificing performance.
Superior Load Capacity: The 30° contact angle and robust chrome steel construction (rings and balls) enable the bearing to support high combined loads, with a radial dynamic load rating of 2803 lbf and a substantial axial static load rating of 7010 lbf.
High Rigidity & Precision: The brass cage ensures stable ball guidance and smooth operation at moderate speeds. Manufactured to ABEC-1 tolerances with a controlled radial internal clearance, it guarantees precise shaft positioning and minimal runout.
Versatile Lubrication & Temperature Range: The open design allows for the application of specialized lubricants to meet specific operational needs, supporting a temperature range from -30°C to 110°C.
KD090AR0 Bearing Typical Application Areas
The KD090AR0 is ideally suited for applications requiring a large bore, a slim profile, and high axial stiffness. Key industries and equipment include:
- Robotics: Rotary joints and precision arm linkages.
- Aerospace & Defense: Gimbals, radar platforms, and control surface actuators.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Medical Equipment: CT scanners and MRI imaging systems.
- Industrial Automation: Rotary tables and high-precision indexing heads.
