Bearings for use in special environments such as clean, vacuum, high-temperature and corrosive environments, are required to have special properties, such as non-magnetic, insulating and high-speed.
For this reason, regular bearings made from bearing steel and lubricant such as oil and grease cannot be used.
JTEKT's special environment EXSEV (short for EXtreme Special EnVironment) series meets these requirements.
Stainless is the standard bearing material, however we offer an abundant variety of bearings to suit any given application.
Bearing varieties include corrosion-resistant stainless steel, ceramic, high-speed tool steel, as well as bearings which use solid lubricants such as high-molecular fluorine and molybdenum disulfide coatings, resin or soft metal.
