K08008XP0 Bearing Product Overview & Core Advantages
The K08008XP0 is a metric thin-section four-point contact ball bearing engineered for applications demanding compact design and high load capacity within minimal cross-sections. As a Reali-Slim series bearing, it provides a superior strength-to-size ratio. Its defining four-point contact design enables it to simultaneously support combined loads—significant radial, axial, and moment loads—in a single, lightweight row. Manufactured to ABEC-1 precision and pre-lubricated, it is an ideal solution for high-reliability, space-constrained machinery requiring smooth and precise motion.
K08008XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K08008 | Indicates the bearing series and size: 80mm bore, 96mm outside diameter, and 8mm width. |
| XP | Signifies the Four Point Contact design, which is the core feature enabling high moment load capacity. |
| 0 | Typically denotes an open (unsealed) construction and standard radial internal clearance. |
K08008XP0 Bearing Structural Features & Performance Benefits
- High Moment Load Capacity: The unique four-point contact geometry between the balls and raceways allows a single bearing to resist substantial load moments (rated at 191 ft-lbf), effectively replacing more complex multi-bearing arrangements.
- Combined Load Support: Engineered to handle combined radial and axial loads simultaneously, with high static load ratings (1894 lbf radial, 4731 lbf axial), ensuring stability under complex loading conditions.
- Space and Weight Savings: As a thin-section bearing with an 8mm width, it minimizes system envelope and weight (0.11 kg), which is critical for robotics and aerospace applications.
- Precision and Durability: Built with Chrome Steel rings and balls and a Brass cage for reliable operation. The ABEC-1 tolerance class guarantees consistent performance and interchangeability.
K08008XP0 Bearing Typical Application Areas
This bearing is specifically designed for compact, high-performance systems, including:
- Robotics: Joints and actuators where space, weight, and moment load capacity are critical.
- Aerospace & Defense: Gimbals, control mechanisms, and satellite positioning systems.
- Medical Equipment: Precision scanners and surgical robot arms.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Automation: Rotary tables and CNC rotary unions.
