This product is a "urethane-coated bearing" where rubber is directly bonded to the outer diameter of the bearing through a curing process. After the curing process, the outer diameter is polished to achieve high precision, low vibration, and low noise. We offer a wide range of standard sizes, and we can also accommodate special sizes and material changes. 【Features】 ■ Rubber is directly bonded to the outer diameter of the bearing through curing ■ High precision, low vibration, and low noise are achieved by polishing the outer diameter after curing ■ A wide variety of standard sizes are available ■ We can also accommodate special sizes and material changes *For more details, please refer to the PDF document or feel free to contact us.

"CASSTOP" is a miniature bearing that does not rust even at pH3. It is made from martensitic stainless steel TBN-6H, created through the adjustment of appropriate components (4 chemical components and trace elements), achieving remarkable corrosion resistance that surpasses SUS440C. Even in environments exposed to acidic and alkaline chemical solutions, saltwater, and rainwater, it provides high reliability and long-lasting operation for various equipment. [Features] ■ Achieves remarkable corrosion resistance that surpasses SUS440C ■ Realizes hardness: HRC59 through unique heat treatment technology ■ Exhibits load-bearing performance equal to or greater than SUS440C by optimizing the internal specifications of the bearing ■ Provides high reliability and long-lasting operation for various equipment *For more details, please refer to the PDF materials or feel free to contact us.

This product is a resin-wrapped bearing that uses high-load capacity JIS standard 69 series bearings. It is made using insert molding, with the width of the resin being wider than that of the bearing, which also increases the pull-out strength. It uses polyacetal resin, and the outer diameter surface is finished by cutting, resulting in a smooth surface with good runout accuracy. We also offer a creep-free resin-wrapped bearing with an inner ring and a creep prevention ring in the same size. 【Features】 ■ The standard outer diameter shape is flat, but it can also accommodate V-grooves and U-grooves. ■ Uses high-load capacity JIS standard 69 series bearings. ■ The width of the resin is wider than that of the bearing, increasing pull-out strength. ■ The outer diameter surface is finished by cutting, resulting in a smooth surface with good runout accuracy. *For more details, please refer to the PDF document or feel free to contact us.

"OAB (Oil-less Air Bearing)" is a product that is difficult to seize even in a solid contact state, offers excellent safety, and is easy to handle. Due to its material design, flow adjustment is easily achievable, and it can be customized for high rigidity specifications, high-speed specifications, and more according to application needs. Additionally, it can be manufactured in various shapes. It can significantly reduce flow compared to self-generating and orifice throttling, achieving labor-saving for air sources and reducing running costs. 【Features】 ■ Suitable throttling can be constructed using unique porous technology ■ Usable in clean rooms ■ Difficult to seize even in solid contact state, offering excellent safety ■ Adopted in equipment requiring reproducibility, such as precision measurement and inspection ■ Performance (allowable load, rigidity, flow) can be customized even with the same dimensions *For more details, please refer to the PDF document or feel free to contact us.
