KF-140 XP0 Bearing Product Overview & Core Advantages
The KF-140 XP0 is a high-performance Four Point Contact Ball Bearing designed for demanding applications requiring exceptional load capacity and precision. As part of the Reali-Slim Open Bearings series with an inch system of measurement, it features a compact, single-row design that provides a large bore relative to its cross-section. Its primary advantage is the ability to simultaneously support high radial loads, axial loads in both directions, and significant load moments, making it an ideal solution for space-constrained, high-rigidity systems.
KF-140 XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KF-140 | Indicates the specific bearing series and size designation (14" bore). |
| XP0 | Signifies an open (unsealed) construction and a specific internal configuration or clearance group. |
Key Configuration: The Open seal type allows for custom lubrication schemes and is suitable for clean environments or applications where the bearing is integrated into a larger, sealed housing.
KF-140 XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The raceway geometry enables a single bearing row to withstand combined radial and axial loads from any direction, as well as high tilting moments. This simplifies assembly and reduces the need for complex multi-bearing arrangements.
- High Load Capacity: Engineered with Chrome Steel rings and balls, this bearing delivers high dynamic and static load ratings (Radial Dynamic: 8775 lbf, Axial Dynamic: 14530 lbf), ensuring long service life under strenuous conditions.
- Precision & Rigidity: Manufactured to ABEC-1 tolerance standards with a controlled radial internal clearance, it provides consistent running accuracy and contributes to the overall system stiffness.
- Optimized Cage: The brass cage ensures stable ball guidance, reduces friction, and is suitable for a wide range of operating speeds.
- Standard Lubrication: The bearing comes pre-lubricated, ready for immediate installation and operation within its specified temperature range.
KF-140 XP0 Bearing Typical Application Areas
- Robotics: Robot rotary joints and manipulator arms.
- Aerospace & Defense: Radar platforms, gun turrets, and missile guidance systems.
- Machine Tool: Rotary tables, indexers, and CNC positioning systems.
- Medical Equipment: CT and MRI scanner gantries.
- Semiconductor Manufacturing: Wafer handling and precision stages.
