Product Description

Product Details

The rings and rolling elements of zirconia full ceramic bearings are made of zirconia (ZrO2) ceramic materials, and the retainers are made of polytetrafluoroethylene (PTFE), nylon 66, polyetherimide, zirconia, silicon nitride, stainless steel or special Made of aviation aluminum. Zirconia full ceramic bearings are non-magnetic, electrically insulating, wear-resistant, resistant to strong acid and alkali corrosion, oil-free self-lubricating, and resistant to high temperatures and colds. They can be used in extremely harsh environments and special working conditions that steel bearings cannot adapt to, and are matched with stainless steel. With the cage or full ball, it can be used in high temperature environments above 450°C, and with PTFE or PEEK cages, it can be used in temperatures above 250°C.
Zirconia full ceramic bearing product features:
1. High speed: It has the advantages of cold resistance, low stress elasticity, high pressure resistance, poor thermal conductivity, light weight, and small friction coefficient. It can be used in high-speed spindles and other high-precision equipment with a speed of 12,000 rpm to 75,000 rpm. middle;
2. High temperature resistance: There will be no expansion caused by temperature difference between the use temperature of 100℃-600℃. Can be used in furnaces, plastic making, steel making and other high temperature equipment;
3. Corrosion resistance: The material itself has corrosion resistance and can be used in fields such as strong acid, strong alkali, inorganic, organic salt, seawater, etc., such as: electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc.
4. Anti-magnetic: Because it is non-magnetic and does not absorb dust, it can reduce premature peeling of bearings and loud noise. Can be used in demagnetization equipment. Precision instruments and other fields.
5. Electrical insulation: Due to its high resistance, it can avoid arc damage to the bearings and can be used in various power equipment requiring insulation.
6. Vacuum: Due to the unique oil-free self-lubricating properties of ceramic materials, in ultra-high vacuum environments, zirconia all-ceramic bearings can overcome the problem that ordinary bearings cannot achieve lubrication.
