Product catalog summary

Overview
The Koyo EXSEV Bearing Series is engineered for extreme environments where standard bearings fail, focusing on semiconductor industry applications, particularly in clean-room and vacuum-chamber settings.

Product Specifications

FA Bearings: Designed for semiconductor and LCD systems, suitable for cleanliness class 1000, temperatures from -100 to 200°C, and pressures down to 10^-5 Pa. Constructed with martensitic stainless steel, fluorocarbon resin cages, and fluoropolymer lubrication.
HD Bearings: Used in carrier and food-processing systems, suitable for cleanliness class 1000, temperatures from -30 to 120°C, with KHD grease lubrication.
Clean Pro Bearings: Ideal for clean-room applications, operating in cleanliness class 10, temperatures from -100 to 200°C, with Clean Pro coating lubrication.
High-temperature Clean Pro Bearings: Enhanced version of Clean Pro Bearings, withstands temperatures up to 260°C.
DL Bearings: Suitable for vacuum environments, cleanliness class 100, temperatures from -30 to 200°C, lubricated with KDL grease.
PN Bearings: For high-temperature applications up to 300°C, using PEEK resin cages and fluoropolymer lubrication.
MO Bearings: Lubricated with molybdenum disulfide, suitable for temperatures up to 350°C.
WS Bearings: Feature tungsten disulfide lubrication for high heat resistance and load performance.
MG Bearings: For ultra-high vacuum applications, using silver-ion plating for lubrication.
High-temperature Hybrid Ceramic Bearings: Use high-speed tool steel rings and ceramic balls, suitable for temperatures up to 500°C.
Corrosion-resistant Bearings: SL and Hybrid Ceramic Bearings for corrosive environments, using precipitation-hardened stainless steel and ceramic materials.

Applications
Applicable in semiconductor manufacturing, LCD manufacturing, vacuum evaporators, and chemical processing systems, designed for extreme conditions like high temperatures, vacuum, and corrosive environments.
