ZrO2/Si3N4 R188 bearing 1/4 x 1/2 x 3/16 Inch full ceramic Ball Bearing R188 Ceramic Bearing

Ceramic bearings as an important machine parts, metal bearings because of its unmatched superior performance, high temperature, super-strength materials in the new world dominate. Over the past decade, in all areas of the national economy has been in an increasingly wide range of applications.

Four bearing material performances in the control condition,as follows:

Ceramic bearing can be applied to high speed, high temperature, low temperature, strong corrosion, strong magnetic field, vacuum and high pressure such as all kinds of bad working condition.
1) high bearing capacity, ceramic material hardness up to 2 times the size of bearing steel, elastic modulus is 1.5 times that of the bearing steel.
2) good heat resistance, the decrease of strength of ceramic materials at high temperature is very small, even at 800 degrees Celsius remained has high strength and mechanical properties, and ceramic material the inflation rate is only 22% of bearing steel.
3) high limit speed, ceramic ball bearings work of rotational speed can reach the same bearing steel bearing limit of more than 1.3 times. 4) low friction temperature, ceramic ball bearings under the speed of 18000 r/min temperature rise is approximately the same conditions in the operation of bearing steel bearing temperature rise 60%.
4) small friction loss, bearing the same model, the quality of the ceramic material is smaller than steel, rolling body during operation by centrifugal force and gyroscopic moment of small, small spin slide.
5) High durability, ceramic materials, high hardness, excellent wear resistance, the working life of the ceramic ball bearing is generally 2 times more than ordinary bearing steel bearing.
6) Good corrosion resistance, ceramic materials can resist hydrochloric acid, sulfuric acid, nitric acid, caustic soda and other kinds of inorganic acid, organic acid, salt, alkali and corrosion of molten metal.
7) Good insulation, low permeability, almost for insulator, permeability is far less than 0.1 H, suitable for any non magnetic parts.
8) The self-lubricating self-lubrication, ceramic bearing is achieved.
