JU040XP0 Bearing Product Overview & Core Advantages
The JU040XP0 is a high-performance thin section sealed bearing designed for applications demanding precision and space optimization. As a Four Point Contact ball bearing, it excels at simultaneously handling combined radial and axial loads from any direction. Its compact cross-section, with a width of only 0.5", makes it ideal for lightweight, high-rigidity designs. Pre-lubricated and sealed, this bearing offers reliable, long-term performance with minimal maintenance, making it a superior choice for precision rotary systems.
JU040XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| JU040 | Specifies the bearing series and size: 4" bore diameter, 4.75" outside diameter. |
| XP | Indicates the Four Point Contact ball bearing construction. |
| 0 | Denotes the bearing is Sealed for contamination protection. |
JU040XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: Enables the bearing to support significant combined radial and axial loads in both directions, simplifying assembly and reducing the need for complex bearing arrangements.
- Thin Section Construction: The slim 0.5" width and optimized cross-section provide substantial weight savings and space efficiency without compromising on load capacity or structural integrity.
- Precision & Rigidity: Manufactured to ABEC-1 tolerance standards, ensuring consistent running accuracy and contributing to system high rigidity.
- Integrated Seal & Lubrication: The sealed design retains factory-applied lubricant and effectively excludes contaminants, resulting in a maintenance-free and long-service-life solution.
- Robust Material Selection: Components made from Chrome Steel and a Brass cage ensure high durability and stable operation across the specified temperature range.
