KF070XP0 Bearing Product Overview & Core Advantages
The KF070XP0 is a Four Point Contact thin section bearing designed for applications demanding high precision and space optimization. As part of the Reali-Slim Open Bearings series, this single-row ball bearing is engineered to simultaneously handle significant combined loads, including radial, axial, and moment loads, within a remarkably compact cross-section. Its inch-system dimensions (7" bore, 9" OD, 0.3125" width) make it ideal for replacing bulky standard bearings, offering superior stiffness and weight savings in high-performance machinery. Manufactured to ABEC-1 precision standards, it ensures reliable operation and long service life.
KF070XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KF | Series identifier for Kaydon® Reali-Slim thin section bearings. |
| 070 | Indicates the cross-section size; a "7" series bearing with a 1" cross-section (9" - 7" = 2" / 2 = 1"). |
| X | Denotes a Four Point Contact ball bearing design. |
| P | Specifies a "Open" (unsealed) configuration. |
| 0 | Radial internal clearance designation. |
KF070XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single bearing to support combined radial, axial, and moment loads efficiently, simplifying assembly and reducing the need for multiple bearing arrangements.
- High Load Capacity: Engineered for demanding applications, it offers a high dynamic load moment rating of 17 ft-lbf and substantial axial static load capacity of 21,870 lbf, ensuring durability under heavy loads.
- Precision & Rigidity: Manufactured from Chrome Steel with a Brass cage and built to ABEC-1 tolerances, this bearing provides consistent performance, high running accuracy, and enhanced system rigidity.
- Space and Weight Saving: The thin section design (0.3125" width) minimizes the required envelope and component weight (3.2 lbs), which is critical in aerospace, robotics, and medical equipment.
- Versatile Lubrication: Supplied as lubricated, it is ready for operation within a wide temperature range of -30°C to 110°C, accommodating various environmental conditions.
KF070XP0 Bearing Typical Application Areas
This bearing is ideally suited for high-precision, compact machinery across multiple industries:
- Robotics: Robot arms, rotary joints, and gearing systems where moment load capacity and compactness are critical.
- Aerospace & Defense: Actuators, control mechanisms, and radar platforms requiring lightweight, high-performance components.
- Medical Equipment: CT scanners, MRI machines, and surgical robots demanding smooth, precise motion.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Automation: Rotary tables, indexing heads, and CNC rotary axes.
