Description
Advantages of zirconia ceramic step bushings
Zirconia ceramic step bushings combine a number of core performance advantages such as high toughness, crack resistance, super wear resistance, high precision, corrosion resistance, electrical insulation and high temperature resistance. In the complex step structure, zirconia material can effectively solve the ordinary ceramic is easy to brittle crack, metal is easy to wear and plastic is easy to deformation of the problem, so that in the high-precision shaft support, automation guidance and complex non-standard mechanical structure performance is more stable and reliable. It can maintain fit precision and step positioning accuracy for a long time, and also significantly extend the life of the equipment and reduce the maintenance frequency, which makes it an ideal upgraded bushing material for high-end precision machinery and automation equipment.
- High toughness and strong crack resistance, complex ladder structure is more reliable
- Superior wear resistance, long-term maintenance of fit accuracy
- High dimensional accuracy for precision shaft assembly
- Excellent corrosion performance, suitable for complex media environment resistance
- Good electrical insulation performance, taking into account the isolation function.
- High surface finish and reduced friction loss

Basic properties of magnesium-stabilized zirconia ceramics
Magnesium-stabilized zirconia ceramics use magnesium oxide (MgO) as a stabilizer for zirconia, and the crystal structure is cubic lattice after molding, which is more stable. Magnesia-zirconia has better resistance to high temperature and humidity because it is not affected by phase migration. Magnesia-zirconia maintains its strength even in humid, high-temperature environments where the mechanical properties of yttrium oxide partially stabilized zirconia begin to deteriorate.
