KF250XP0 Bearing Product Overview & Core Advantages
The KF250XP0 is a high-performance Four Point Contact thin section ball bearing engineered for applications requiring exceptional moment load capacity within compact spaces. This inch series bearing features a single row design with an open construction, delivering a superior combination of high static and dynamic load ratings. Its optimized geometry allows it to simultaneously support radial loads, axial loads, and significant load moments, making it an ideal solution for high-precision, high-rigidity applications where space and weight are critical constraints.
KF250XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KF | Indicates the Reali-Slim® series thin section bearing family. |
| 250 | Specifies the nominal bore diameter of 25.0 inches. |
| XP | Denotes the cross-section size (width and OD proportional to bore). |
| 0 | Signifies an Open (unsealed) construction. |
KF250XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The raceway geometry allows each ball to make contact at four points, enabling the bearing to efficiently support combined radial, axial, and moment loads in a single, compact unit. This eliminates the need for complex multi-bearing arrangements.
High Load Capacity: Engineered from Chrome Steel for both rings and balls, this bearing delivers exceptional strength. It boasts a high Dynamic Load Moment rating of 115,037 lbf-in and a Static Load Moment of 374,200 lbf-in, ensuring reliable performance under demanding conditions.
Precision & Rigidity: Manufactured to ABEC-1 tolerance class with tight dimensional control on bore, OD, and width. The specified radial internal clearance ensures optimal preload and system stiffness for precise motion control.
Reali-Slim® Profile: With a minimal cross-section (0.75" width for a 25" bore), it provides maximum performance with minimal weight and space consumption, contributing to overall system efficiency.
KF250XP0 Bearing Typical Application Areas
- Robotics: Robotic arms and joints requiring high moment load capacity and compact design.
- Aerospace & Defense: Gimbals, radar platforms, and satellite positioning systems.
- Medical Equipment: CT scanners, MRI machines, and advanced surgical robotics.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
- Industrial Automation: Rotary tables, indexing heads, and precision turntables.
