KD080XPO Bearing Product Overview & Core Advantages
The KD080XPO is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series, designed in inch dimensions for applications demanding compact cross-sections and high load capacity. This single row bearing is engineered to simultaneously support significant combined radial and axial loads from any direction, making it an ideal solution for space-constrained, high-precision machinery. Its ABEC-1 precision and robust construction ensure reliable operation in demanding environments.
KD080XPO Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KD | Kaydon® Reali-Slim bearing series identifier |
| 080 | Bore diameter code for 8 inches |
| X | Cross-section series designation (e.g., X = 0.5" width for 8" bore) |
| P | Four Point Contact design |
| O | Open (unsealed) construction |
KD080XPO Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows the bearing to handle combined radial, axial, and moment loads efficiently with a single bearing row, simplifying system design and saving space.
- High Load Capacity: Engineered with Chrome Steel rings and balls, it offers high dynamic and static load ratings (Radial Dynamic: 3338 lbf, Axial Static: 14540 lbf), ensuring durability under heavy loads.
- Thin-Section & Lightweight: With a compact cross-section (0.5" width) and low weight (1.53 lbs), it enables the design of lighter, more compact machinery without sacrificing performance.
- Precision & Stability: Manufactured to ABEC-1 tolerance class with a controlled radial internal clearance (0.0000 – 0.0005"), providing consistent running accuracy and smooth operation.
- Robust Cage: The brass cage ensures stable ball guidance, suitable for applications with complex motion profiles.
KD080XPO Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a large diameter, slim profile, and high load capacity, including:
- Robotics (Rotary joints and actuators)
- Aerospace & Defense (Radar platforms, gimbal systems)
- Medical Equipment (CT scanners, surgical robots)
- Machine Tool (Rotary tables, indexing heads)
- Semiconductor Manufacturing Equipment
