As an important mechanical component, 1305 ceramic bearings are at the forefront of the new materials world due to their excellent performance that metal bearings cannot match, such as high temperature resistance and super strength. In the past decade, it has been increasingly widely applied in various fields of national economy and people's livelihood.

Zirconia ceramic bearings: Full ceramic bearings have characteristics such as resistance to magnetic and electrical insulation, wear and corrosion, oil-free self-lubricating, high temperature and cold resistance, and can be used in extremely harsh environments and special working conditions. The collar and rolling elements are made of zirconia (ZrO2) ceramic material, and the retainer uses polytetrafluoroethylene (PTFE) as the standard configuration. Generally, glass fiber reinforced nylon 66 (RPA66-25), special engineering plastics (PEEK, PI), stainless steel (AISISUS316), brass (Cu), etc. can also be used.

Advantages of ceramic bearings

1. Due to the fact that ceramics are almost resistant to corrosion, ceramic rolling bearings are suitable for operation under harsh conditions filled with corrosive media.

2. Due to the lower density and lighter weight of ceramic rolling balls compared to steel, the centrifugal effect on the outer ring during rotation can be reduced by 40%, thereby greatly extending their service life.

3. Ceramics are less affected by thermal expansion and contraction than steel, so when the clearance between bearings is constant, bearings can be allowed to work in environments with significant temperature differences.

4. Due to the higher elastic modulus of ceramics compared to steel, they are less prone to deformation under stress, which is beneficial for improving working speed and achieving higher accuracy.
