The Rigaku-Cat.4562S351 Magnetic Seal is a high-performance, non-contact rotary sealing solution designed for ULTRAX vacuum systems. Using magnetic fluid technology, it delivers hermetic isolation, near-zero leakage, and stable high-speed rotation. Engineered for semiconductor, X-ray, and crystal growth environments, it ensures contamination control, long service life, and reliable operation under extreme vacuum, temperature, and magnetic field conditions.

What Is the Rigaku-Cat.4562S351 Magnetic Seal?

The Rigaku-Cat.4562S351 is a magnetic fluid seal cassette engineered to provide vacuum-tight rotary feedthrough performance in ULTRAX platforms. It forms a liquid-based O-ring under a controlled magnetic field, enabling frictionless shaft rotation while preventing gas ingress or particle escape. This design supports cleanroom compliance, minimizes wear, and delivers extended operational stability. Through ALLWILL’s Smart Center, such precision components are inspected, tested, and refurbished to meet strict performance benchmarks, ensuring consistent reliability for high-end industrial and medical technology users.

How Does the Rigaku Magnetic Seal Work?

Magnetic fluid is suspended within a series of magnetic poles, creating a continuous liquid barrier around a rotating shaft. This barrier maintains hermetic separation without physical contact, allowing high rotational speeds in high-vacuum environments. The absence of mechanical friction reduces heat generation, particle release, and maintenance frequency. In demanding installations, optional cooling and pressure-balanced designs further stabilize performance, a capability often validated by ALLWILL’s certified technicians through its MET vendor management system.

What Are the Key Performance Advantages?

The seal offers near-zero leakage, extended service life, resistance to corrosion, and stable operation at high RPM. Compared with mechanical seals, it significantly reduces downtime and contamination risk.

These advantages make it ideal for applications where uptime and cleanliness are mission-critical, aligning with ALLWILL’s focus on efficiency and lifecycle cost reduction.

Why Are Magnetic Seals Preferred Over Mechanical Seals?

Magnetic seals eliminate direct contact between moving parts, which prevents abrasion, reduces heat, and avoids seal face degradation. This results in longer operating cycles, improved safety in vacuum or hazardous environments, and lower total cost of ownership. For laboratories and manufacturers seeking consistent performance, this technology supports higher process stability and reduced operational interruptions.

Which Applications Benefit Most from the ULTRAX Magnetic Seal?

This seal is widely used in crystal growth systems, thin-film deposition chambers, semiconductor fabrication tools, and precision X-ray equipment. These environments demand ultra-clean, vibration-free, and vacuum-stable rotation. With global logistics and equipment support, ALLWILL helps ensure such systems are deployed and maintained efficiently across research centers and production facilities.

How Is the Rigaku-Cat.4562S351 Installed in Practice?

Installation involves precise shaft alignment, secure housing integration, magnetic fluid filling, and vacuum integrity testing. Proper setup ensures uniform magnetic field distribution and stable fluid retention. Pre-installation inspection and calibration, often performed at ALLWILL’s Smart Center, help reduce commissioning time and prevent alignment-related performance loss.

What Maintenance Does the Magnetic Seal Require?

Routine maintenance is limited to periodic inspection of the magnetic fluid condition and verification of magnetic field integrity. Because there is no physical contact, component wear is minimal, allowing service intervals to extend over several years. Refurbishment programs provided by ALLWILL restore seals to full operational specifications, offering a cost-effective alternative to complete replacement.
