Special environments bearing SE series

ball bearingsingle-rowsteel

These bearings have an optimal operation in extreme environments like clean, vacuum, high temperature, corrosive and contaminating conditions. They are already being used in an extensive range of applications and state of the art technologies. Ceramic bearings consist out of components made from ceramic and can be used in applications where conventional bearings are not suited for. They have special characteristics which steel bearings do not have such as being non-magnetic or insulating. Ceramic bearings are highly heat resistant, have a longer service life and can be divided into Full Ceramic Bearings and Hybrid Ceramic Bearings. The components of our Full Ceramic Bearings are all made of ceramic. The Hybrid Ceramic Bearings have only the rolling elements which are from ceramic. The outer and inner ring of the Hybrid Ceramic Bearing is made from special steel, including high carbon chromium bearings steel. Furthermore the cage can be made of metallic material, resin or composite material depending on the intended operating conditions of the bearing. Bearings made of stainless steel without rust preventive oil are perfectly suitable for operation in clean environments. This bearing can be used in combination with an amount of low particle emission type of lubricant based on the operating conditions such as temperature, load and rotational speed. At JTEKT these special Koyo branded bearings are being lubricated with a Clean Pro coating or fluorinated grease. Fluorinated grease is superior to solid lubricants in load carrying capability and high speed operation. This grease can be used in applications where a scattering of slight amount of fluorinated oil is acceptable.
