JA040XP0 Bearing Product Overview & Core Advantages
The JA040XP0 is a thin section sealed bearing designed for applications demanding compact design and high precision. As a Four Point Contact ball bearing, it excels at simultaneously handling combined radial loads and axial loads from any direction. Its inch-series construction and ABEC-1 precision make it ideal for high-reliability, space-constrained systems requiring smooth operation and long service life.
JA040XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| JA040 | Basic bearing designation indicating specific dimensions (4" bore, 4.5" OD) |
| XP0 | Sealed construction with pre-applied lubrication |
JA040XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: Enables the bearing to support significant combined loads (radial, axial, and moment loads) in a compact 0.25" cross-section, providing exceptional load capacity for its size.
- Sealed Construction: Integrated seals protect against contamination and retain lubricant, ensuring consistent performance and extended service life in demanding environments.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with optimized radial internal clearance (0.0000 – 0.0005") for smooth, precise operation.
- Robust Material Selection: Chrome steel rings and balls combined with a brass cage provide excellent durability and reliable performance across a wide temperature range (-30°C to 110°C).
JA040XP0 Bearing Typical Application Areas
- Robotics and automation systems (joints, actuators)
- Aerospace components (control mechanisms, instrumentation)
- Medical equipment (imaging systems, surgical devices)
- Semiconductor manufacturing equipment
- Precision industrial machinery requiring compact bearing solutions
