The standard material for the dust cover of NSAR bearings is cold-rolled electro-tin-plated steel plate, and AISI-300 stainless steel is sometimes used.
The sealing ring mainly uses nitrile rubber as the material. For high temperature environments, fluorine rubber and silicone rubber are also widely used.

Warning! Fluorine rubber is safe and harmless under normal working conditions below 200°C, but when it exceeds the extreme temperature of 300°C, which is equivalent to the fire of cutting steel pipes, fluorine rubber will release smoke. Inhalation of these fumes is harmful to the human body, including the eyes. In addition, care should be taken to avoid contact with the skin.
NSAR are widely used in household appliance. micro-motors electrical tools garden machinery, motorcycles,automobiles,medical equipment, sports machinery, textile machinery and agricultural machinery.
The bearings we manufacture are all low noise,low vibration,low friction, high precision, high sealed,high turning speed and long life.
Quality is the key point for the NSAR. bearing’s growth and development, which always regards the improvement of high quality and service as the long-term-development strategy. NSAR has passed IS09001: 2000, 1S09001: 2008, and will struggle for the NSAR in long term.
