The ferrule of linear bearing have two kinds of material: Gcr15 (SUJ2) chrome steel and 9Cr18 (SU440C) stainless steel, retainer have three kinds material: POM engineering plastic, low carbon steel and stainless steel, rubber seal made up of NBR nitrile butadiene rubber, the steel seal have two kinds material: 65Mn spring steel and stainless steel, the ferrule of KH series is made from of carbonitriding of low carbon steel.
The choose of the linear bearing: POM engineering plastic can bear the temperature -20° ~80° Working temperature, steel retainer can bear the temperature -40° ~125° Working temperature.
Linear bearing are the most widely-use and economy product among the linear motion track rollers, and they can suit to the cylindrical track.
