KF047XP0 Bearing Product Overview & Core Advantages
The KF047XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series, designed for applications demanding compact cross-sections and high load capacity. This single row bearing is engineered to simultaneously support combined radial loads, axial loads in both directions, and significant moment loads. Its inch-dimensioned, thin-section design provides a space-saving solution without compromising on strength, making it ideal for high-precision machinery where rigidity and accuracy are paramount. Manufactured to ABEC-1 precision tolerances, it ensures reliable performance in demanding operational environments.
KF047XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Benefit |
|---|---|---|
| KF | Kaydon® Reali-Slim® Bearing Series Prefix | Identifies the product family of thin-section bearings. |
| 047 | Cross-Section Designation | Indicates a specific, ultra-thin radial cross-section relative to the bore diameter. |
| X | Four Point Contact Design | Enables the bearing to handle combined radial, thrust, and moment loads efficiently in a single row. |
| P | ABEC-1 Precision Class | Specifies the dimensional and running accuracy tolerance level. |
| 0 | Radial Internal Clearance (RIN C0) | Defines a specific internal fit (0.0000 – 0.0005") for optimal performance under light loads and precise alignment. |
KF047XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The raceway geometry allows each ball to make contact at four points. This unique structure enables a single bearing to replace complex dual-bearing arrangements, supporting substantial moment loads (10 ft-lbf rated) in addition to high axial static load capacity (15,520 lbf) and radial loads.
Thin-Section Construction: With a consistent, slim cross-section (0.75" width), this bearing minimizes the required envelope size and system weight (2.2 lbs), enabling compact and lightweight machine designs without sacrificing load capacity.
High-Performance Materials: The use of Chrome Steel for rings and balls, combined with a Brass cage, ensures high strength, durability, and stable operation across a wide temperature range (-30°C to 110°C).
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight bore, OD, and width tolerances, the KF047XP0 guarantees high running accuracy and high rigidity for precise positioning applications.
KF047XP0 Bearing Typical Application Areas
The KF047XP0 is ideally suited for applications requiring a compact, high-capacity bearing solution. Key industries and equipment include:
- Robotics: Robotic arms, rotary joints, and actuators.
- Aerospace & Defense: Radar platforms, gimbals, and missile guidance systems.
- Machine Tool: Rotary tables, indexers, and CNC positioning stages.
