J05008XP0 Bearing Product Overview & Core Advantages
The J05008XP0 is a metric thin-section four-point contact ball bearing engineered for applications demanding compact design and high precision. As part of the Reali-Slim mm Metric Bearings series, its single-row construction with a sealed design provides exceptional performance in a minimal cross-section. A key advantage is its ability to support combined loads, including significant radial, axial, and moment loads simultaneously. Manufactured to ABEC-1 precision tolerances and pre-lubricated, it is an ideal solution for high-reliability, space-constrained machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| J05008 | Indicates the bearing series and nominal dimensions: 50mm bore, 66mm outside diameter, 8mm width. |
| XP0 | Signifies a specific variant within the Reali-Slim series, typically denoting a sealed construction and standard internal clearance for general applications. |
J05008XP0 Bearing Structural Features & Performance Benefits
- Four-Point Contact Design: The single row of balls makes contact with the raceways at four points, enabling the bearing to efficiently support combined radial, axial, and moment loads in a very slim profile.
- High Load Capacity: Despite its thin section, it offers a high dynamic load rating (1014 lbf radial, 1468 lbf axial) and static load rating (1224 lbf radial, 3062 lbf axial), making it robust for its size.
- Sealed & Lubricated for Life: The integrated seals protect against contamination and retain lubricant, providing maintenance-free operation and extended service life within the specified temperature range (-30°C to 110°C).
- Precision Construction: Manufactured from chrome steel with a brass cage and built to ABEC-1 tolerances, it ensures smooth, reliable, and precise rotation.
J05008XP0 Bearing Typical Application Areas
This bearing is ideally suited for compact and precision mechanisms, including:
- Robotics (joints, actuators)
- Aerospace & Defense systems (gimbals, control mechanisms)
- Medical Equipment (scanners, surgical robots)
- Semiconductor Manufacturing equipment
- Optical Instrumentation and rotary tables
