JA030XP0 Bearing Product Overview & Core Advantages
The JA030XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Sealed Bearings series, designed for applications demanding compact cross-sections and high load capacity. This thin section bearing features a single row construction with sealed design, enabling it to simultaneously handle combined radial loads, axial loads in both directions, and moment loads. Its precision ABEC-1 tolerance and optimized lubrication make it ideal for high-reliability, space-constrained systems requiring smooth operation and long service life.
JA030XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| JA030XP0 | Complete bearing designation | Identifies specific thin-section sealed bearing |
| Sealed | Integrated sealing system | Contaminant exclusion and lubricant retention |
| Four Point Contact | Ball-raceway contact geometry | Superior moment load capacity and rigidity |
| Lubricated | Factory pre-lubricated | Reduced maintenance and immediate operation |
JA030XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique ball-raceway geometry provides exceptional moment load capacity (785 ft-lbf rated load moment) while maintaining compact bearing dimensions (3" bore × 3.5" OD × 0.25" width).
High Load Capacity: Engineered to handle significant combined loads with dynamic ratings of 643 lbf radial and 1010 lbf axial, plus static ratings of 990 lbf radial and 2470 lbf axial.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore/OD tolerance: -0.0006"–0") for smooth, precise operation in demanding applications.
Sealed & Lubricated Construction: The integrated sealing system combined with factory-applied lubrication ensures contamination protection and reliable performance across the operating temperature range (-30°C to 110°C).
Premium Materials: Chrome steel rings and balls with brass cage provide excellent durability and corrosion resistance in challenging environments.
