WA040XP0 Bearing Product Overview & Core Advantages
The WA040XP0 is a high-performance **Four Point Contact Ball Bearing** from the **Reali-Slim Sealed Bearings** series, designed with an ultra-thin cross-section for space-constrained applications. This **precision bearing** excels in handling complex **combined loads**, including significant radial and axial loads in both directions, simultaneously. Its compact design, featuring a 0.25" width, offers a high load capacity within a minimal envelope, making it ideal for applications demanding **high rigidity** and reliable performance. Manufactured entirely from **stainless steel** and pre-lubricated, it provides excellent corrosion resistance and long-term operational stability.
WA040XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| WA040 | Denotes the specific bearing series and size designation within the Reali-Slim family. |
| XP0 | Indicates the bearing is Sealed on both sides, providing superior protection against contaminants. The "0" suffix typically refers to a standard radial internal clearance for this series. |
WA040XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: This unique geometry allows a single row bearing to support substantial combined radial and axial loads from any direction, simplifying assembly and reducing the need for multiple bearing arrangements.
- Ultra-Thin Section: The slim 0.25" width provides significant space and weight savings, enabling more compact and efficient machinery designs without sacrificing performance.
- Sealed & Lubricated for Life: Integrated seals effectively shield the internal components from dust and moisture. Pre-applied lubrication ensures consistent performance and offers a maintenance-free solution throughout the bearing's service life.
- All-Stainless Steel Construction: Rings, balls, and cage are manufactured from stainless steel, offering excellent corrosion resistance and suitability for harsh environments or clean applications.
- Precision ABEC-1 Tolerance: Guarantees consistent running accuracy and smooth operation, contributing to the overall high rigidity and reliability of the application.
WA040XP0 Bearing Typical Application Areas
This bearing is engineered for applications where space is at a premium and high load capacity is critical. Key industries and equipment include:
- Robotics: Joints, actuators, and rotary modules.
- Aerospace & Defense: Guidance systems, gimbals, and control surfaces.
- Medical Equipment: Surgical robots, scanners, and precision instruments.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
