JB045XP0 Bearing Product Overview & Core Advantages
The JB045XP0 is a thin-section four-point contact ball bearing engineered for applications requiring compact design and high precision. This sealed bearing features a single-row construction capable of simultaneously handling combined radial and axial loads from any direction, making it ideal for space-constrained, high-reliability systems. Manufactured to ABEC-1 precision with pre-applied lubrication, it delivers consistent performance and long service life.
JB045XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| JB045 | Reali-Slim series with 4.5" bore diameter | Ultra-thin cross-section for space optimization |
| XP0 | Sealed construction with four-point contact | Superior contamination protection and multi-directional load capacity |
JB045XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: Enables the bearing to handle combined radial and axial loads from any direction with a single bearing row, providing exceptional load moment capacity (2 ft-lbf rated load moment).
Thin-Section Construction: With a consistent 0.3125" width across all sizes, this design minimizes envelope dimensions while maintaining structural integrity for compact machinery applications.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore/OD tolerance: -0.0008" to 0") ensures smooth operation and precise positioning.
Sealed & Lubricated: Integrated seals protect against contamination while factory-applied lubrication provides maintenance-free operation across a broad temperature range (-30°C to 110°C).
Premium Materials: Chrome steel rings and balls with brass cage construction deliver excellent wear resistance and durability under dynamic loading conditions.
JB045XP0 Bearing Typical Application Areas
