What are the characteristics of pot ptfe bearing?

2,660 Published by Mar 20,2020

pot ptfe bearing has the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, magnetic and electrical insulation, oil-free self-lubrication, high speed and so on.
pot ptfe bearing can be used in extremely harsh environments and special working conditions, and can be widely used in aviation, aerospace, marine, petroleum, chemical, automotive, electronic equipment, metallurgy, power, textile, pumps, equipment, scientific research and defense and military fields , Is a high-tech product for the application of new materials.

The ferrules and rolling elements of the pot ptfe bearing are made of all-ceramic materials, including zirconia (ZrO2), silicon nitride (Si3N4), and silicon carbide (Sic). The holder is made of polytetrafluoroethylene, nylon 66, polyetherimide, zirconia, silicon nitride, stainless steel or special aviation aluminum, thereby expanding the application area of ceramic bearings.

(1) High-speed pot ptfe bearing: It has the advantages of cold resistance, low stress elasticity, high pressure resistance, poor thermal conductivity, light weight, and low coefficient of friction. It can be applied to high-speed spindles from 12000 rpm to 75,000 rpm And other high-precision equipment;
(2) High temperature resistant pot ptfe bearing: The material itself has a high temperature resistance of 1200 ° C and good self-lubrication. The use temperature does not cause expansion due to temperature differences between 100 ° C and 800 ° C. Can be used in furnaces, plastics, steel and other high temperature equipment;

(3) Corrosion-resistant pot ptfe bearing: The material itself has the characteristics of corrosion resistance, and can be applied in the fields of strong acid, strong alkali, inorganic, organic salt, seawater, etc. ** Equipment, etc.(4) Anti-magnetic pot ptfe bearing: Because it is non-magnetic and dust-free, it can reduce the bearing's premature peeling and high noise. Can be used in demagnetization equipment. Precision instruments and other fields.
(5) Electric insulation pot ptfe bearing: Due to the high resistance, it can avoid arc damage to the bearing, and can be used in various electrical equipment that requires insulation.
(6) Vacuum pot ptfe bearing: Due to the unique oil-free self-lubricating characteristics of ceramic materials, in the ultra-high vacuum environment, it can overcome the problem that ordinary bearings cannot achieve lubrication.

Note: The above five categories of pot ptfe bearing, the same set of pot ptfe bearing can be applied to high temperature, high speed, acid and alkali, magnetic field, non-insulation, but because the material properties are different (please refer to the performance table of rare earth ceramic materials), please ask customers When selecting a product, select the ceramic bearing with the most suitable material according to the application.
