Detailed explanation of zirconia ceramic bearings:

Zirconia ceramic bearings are all ceramic bearings with characteristics such as resistance to magnetic and electrical insulation, wear resistance, corrosion resistance, self lubrication, high temperature resistance, and high cold resistance. They 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 (GRPA66-25), special engineering plastics (PEEK, PI), stainless steel (AISI SUS316, SUS304), brass (Cu), etc. can also be used.

Features:

1. Corrosion resistance: The material itself has the characteristic of corrosion resistance and can be applied in fields such as strong acids, strong bases, inorganic and organic salts, seawater, etc., other than hydrofluoric acid, such as electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc.

2. High temperature resistance: Ceramic bearings with retainers can be used at temperatures between 180 ℃ and 260 ℃ without causing expansion due to temperature differences. Zirconia ceramic bearings filled with balls can be used at temperatures ranging from 300-400 ℃ and can be applied in high-temperature equipment such as furnaces, plastic making, and steel making;

3. Self lubrication: Ceramic bearings have good self-lubricating performance due to their low friction coefficient and good surface smoothness, especially silicon nitride materials have better lubrication performance! So ceramic bearings do not require any grease to be added. In ultra-high vacuum environments, ceramic bearings can overcome the difficulty of lubrication that ordinary bearings cannot achieve.

4. Antimagnetic: Due to its non-magnetic nature, it does not attract dust, which can reduce premature bearing peeling and high noise. Can be used in demagnetization equipment. Precision instruments and other fields.

5. Electrical insulation: Due to high electrical resistance, it can prevent arc damage to bearings and can be used in various electrical equipment that require insulation.

Main uses: medical equipment, optical instruments, printing machinery, low-temperature engineering, food processing machinery, reaction vessels, high-temperature furnaces, bicycles and other transportation vehicles
