NSK Grease LG2



This grease was developed by NSK to be exclusively used for linear guides, ball screws and Monocarriers in clean room. Compared to the fluorine grease which are commonly used in clean room, LG2 has several advantages such as: Higher in lubrication function, Longer lubrication life, More stable torque (resistant to wear) and Higher rust prevention. In dust generation, LG2 is more than equal to fluorine grease in keeping dust volume low. Since the base oil is not a special oil but mineral oil, LG2 can be handled in the same manner as general greases.



LG2 is a lubrication grease for rolling element products such as linear guides, ball screws, and monocarriers for semiconductor and liquid crystal display (LCD) processing equipment which require a highly clean environment. It is a standard grease for NSK standard ball screw USS type.
