A bearing that achieves groundbreaking corrosion resistance and load-bearing performance. Adopted in environments where chemical solutions with pH 3 to pH 12 are present (such as medical devices and food machinery)!
Castop is a bearing that achieves load-bearing performance with a unique heat treatment technology using the newly developed material TBN-6H, which demonstrates corrosion resistance superior to conventional stainless steel SUS440C. Thanks to the addition and adjustment of appropriate components (4 chemical components × trace elements), this newly developed material realizes a dramatic improvement in corrosion resistance over SUS440C. Furthermore, with our unique heat treatment technology achieving HRC59, and through the optimization of internal specifications, it exhibits load-bearing performance equal to or greater than that of SUS440C. We provide high reliability and long operational life for various equipment in saline, rainwater, and alkaline environments. 【Features】 ■ The newly developed material, born from the addition and adjustment of appropriate components (4 chemical components × trace elements), achieves dramatic corrosion resistance surpassing SUS440C. → Newly developed high-corrosion-resistant martensitic stainless steel TBN-6H ■ Achieves HRC59 with our unique heat treatment technology ■ Exhibits load-bearing performance equal to or greater than that of SUS440C through optimization of internal specifications ■ Provides high reliability and long operational life for various equipment in saline, rainwater, and alkaline environments *For product details, please download the PDF materials or contact us.
