Product detail
Ceramic bushing is a ceramic tube for industrial parts. Ceramic bushing can be used together with industrial components by welding, bonding, or embedding with metal. Generally, ceramic bushing is a component used to protect equipment. Its use can reduce equipment wear, vibration, and noise, and has an anti-corrosion effect. It can also facilitate the maintenance of mechanical equipment, simplify equipment structure, and manufacturing processes. In valve applications, bushing is installed on the valve stem to reduce valve leakage and provide sealing. In bearing applications, the use of bushing can reduce wear between the bearing and shaft housing, and prevent an increase in clearance between the shaft and hole.
Based on these applications, alumina ceramic bushings possess the primary characteristics of alumina materials:
Good strength and stiffness
Extremely high hardness (Moh's hardness 9)
Exceptional resistance to wear
Good corrosion resistance to acid and alkali
High temperature resistance up to 1750℃
Excellent electrical insulation
Low dielectric constant and dielectric loss
Mascera offers alumina ceramic bushings in various purities including 95%, 96%, 99%, 99.5%, and 99.8%. The higher purity options provide increased strength, wear resistance, corrosion resistance, and working temperature. We can customize the size of alumina ceramic bushings and are skilled in various molding methods and high-precision machining of sintered parts. Additionally, we provide ceramic bushings made of zirconia, silicon carbide, silicon nitride, and boron nitride materials. Contact us for any inquiries.
