KF140XP0 Bearing Product Overview & Core Advantages
The KF140XP0 is a high-performance thin section bearing designed for applications requiring maximum load capacity in minimal space. As a Four Point Contact ball bearing, it excels at simultaneously handling combined radial and axial loads from any direction. Its inch-series dimensions (14" bore, 15.5" OD, 0.75" width) and ABEC-1 precision make it ideal for high-rigidity, compact assemblies in demanding industrial environments. The open design allows for versatile lubrication strategies, ensuring optimal performance across its specified temperature range.
KF140XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KF140 | Indicates the specific bearing series and size designation for a 14" bore thin section bearing. |
| XP0 | Signifies an Open construction (no seals/shields) and specific internal configuration for Four Point Contact load handling. |
KF140XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The single-row construction features a raceway geometry that creates four points of contact between the balls and raceways. This enables the bearing to support significant combined radial and axial loads in both directions, effectively functioning like a pair of angular contact bearings.
- High Load Capacity & Rigidity: Engineered with a brass cage for stability, this bearing offers exceptional static and dynamic load ratings (e.g., Radial Static: 16,650 lbf, Axial Dynamic: 14,530 lbf). Its robust chrome steel construction ensures high rigidity and dimensional stability under heavy load moments (Static Load Moment: 122,800 lbf).
- Precision & Versatility: Manufactured to ABEC-1 tolerance standards with a controlled radial internal clearance, it provides reliable, repeatable performance. The open design allows for custom lubrication to suit specific application needs, optimizing performance for high-speed or extreme temperature conditions (-30°C to 110°C).
- Space-Saving Profile: As a Reali-Slim thin section bearing, it provides a large bore diameter relative to its cross-section, enabling lightweight, compact designs without sacrificing strength or load capacity.
KF140XP0 Bearing Typical Application Areas
This bearing is engineered for high-performance machinery where space constraints and high load demands coexist. Key applications include:
- Robotics & Automation: Robot joints, rotary actuators, and precision positioning stages.
- Aerospace & Defense: Radar platforms, gimbal systems, and flight control mechanisms.
- Medical Equipment: CT scanners, MRI machines, and surgical robot rotators.
- Semiconductor Manufacturing: Wafer handling robots, precision index tables, and stepper stages.
- Industrial Machinery: Rotary tables, turntables, and swivel joints in material handling systems.
