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.
This bearing has a fluoropolymer gel coating on its rolling surfaces as the lubricant.
This bearing has a fluoropolymer coating on its rolling surface as the lubricant.
This bearing is lubricated with a fluoropolymer coating over the entire surface of all bearing components.
This bearing is lubricated with the packed fluorinated EXSEV®-EX (Grease), which is suitable for use in clean environments and vacuum environments.
Compliant with environmental regulations (does not contain PFOA)
This bearing is lubricated with a solid fluoropolymer lubricant,which offers superior lubrication performance. The cage is made from a low-particle-emission fluorocarbon resin.
This bearing uses a silicon carbide ceramic material, which is resistant to strong acids and alkalis.
This bearing has its components made of corrosion resistant silicon nitride and is lubricated with fluoropolymer. This bearing can be used even in a highly corrosive solution.
This bearing has its components made of silicon nitride ceramic and uses fluoropolymer as the lubricant. It is typically used in vacuum and corrosive environments.
This bearing uses ceramic (zirconia) for its material and is lubricated with the solid lubricant of the molded PEEK resin cage. It can be used in corrosive liquids or water and also has excellent impact resistance.
This bearing uses a stainless steel variety that has excellent corrosion resistance. As the lubricant, fluoropolymer is used. It is compatible with underwater use.
This bearing has its components made of stainless steel, and is lubricated with lithium containing EXSEV®-KHD (Grease), which is packed in adequate amounts. This bearing is suitable for use in slightly corrosive environments.
This bearing has all components made of ceramic for use in an ultrahigh temperature environments. No cage is provided. Being an angular contact ball bearing, this bearing is normally used in pairs.
The bearings are filled with fluorinated grease capable of handling high temperatures even up to 350˚C.
This bearing has extremely heat resistant tungsten disulfide included in the separator material as the lubricant.
This bearing has silver ion plated on the stainless steel balls, as the lubricant.
This bearing has a highly heat resistant solid lubricant, such as molybdenum disulfide included in the cage material.
This bearing has molybdenum disulfide baked on the surface of the stainless steel cage, as the lubricant.
This bearing uses non-magnetic stainless steel. It includes fluoropolymer as the lubricant. This bearing can be used in a vacuum environment.
This bearing is a standard hybrid ceramic bearing. Lubricated with grease or oil, it can be used as an insulating bearing or high speed bearing.
The linear motion ball bearings are a high precision product that moves linearly in axial directions while having rolling contact with the shaft. Having balls, retainer and shields housed in an external cylinder, this compact bearing moves linearly without limit to the stroke distance.
The Linear Way Bearing Units have a slide unit in which balls circulate, allowing the slide unit to move linearly on the track rail without limit. High precision linear motion can be obtained easily by fixing the slide unit and track rail with bolts.
The Cross Roller Way Bearing Unit is a linear motion bearing unit consisting of two raceway bases. Each base has one longitudinal plane cut into a V shape, which serves as the rolling surface. Two bases are in contact on each of the other's V-cut surface, and cylindrical rollers with a retainer are placed between the surfaces. Any pair of adjacent cylindrical rollers is directed at right angles to each other, thus enabling smooth and extremely accurate linear motion.
