Royal molded bellows

Royal molded bellows

Corrosion-resistant, high-temperature resistant, long-life design molded bellows.

We have standardized formed bellows made of Hastelloy® C22 for various movable parts of vacuum equipment (especially semiconductor manufacturing equipment) and for valve shaft seals. ■ Excellent corrosion resistance - It has superior corrosion resistance compared to other Ni-Cr-Mo alloys. - It prevents stress corrosion cracking even against Cl2 and HBr gases. ■ High-temperature strength - It outperforms the room temperature tensile strength and 0.2% yield strength of SUS316L at 650°C. ■ Long lifespan design possible - A lifespan design of 10^6 cycles is achievable with formed bellows. - The dimensions during use have been further reduced compared to conventional designs, allowing for a more compact design.

High-performance molded bellows "LFB/SFB"

High-performance molded bellows "LFB/SFB"

Compact design is possible! High-performance formed bellows that achieve a lifespan comparable to welded bellows.

The "LFB/SFB" is a high-performance molded bellows handled by Irie Koken. The "LFB" is a royal molded bellows that achieves a high lifespan comparable to welded bellows (1 million cycles). It has excellent corrosion resistance and prevents stress corrosion cracking even against Cl2 and HBr gases. It outperforms SUS316L in terms of room temperature tensile strength and 0.2% yield strength at 650°. Additionally, the "SFB" is a super molded bellows that can be designed to be more than 50% more compact than conventional molded bellows. 【Features】 ■ Achieves a high lifespan comparable to welded bellows (1 million cycles) ■ Spring constant is less than 1/2 of conventional molded bellows ■ Can be designed to be more than 50% more compact than conventional molded bellows *For more details, please refer to the PDF materials or feel free to contact us.
