NSK Grease Clean
NSK Grease LG2 Reference no. : NSK GRS LG2
Quantity: 80 g Tube color: Blue
Feature This grease was developed by NSK to be exclusively used for linear guides, ball screws and
Application 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 a 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.
* Wash the linear guides and ball screws to remove oil prior to applying Clean Grease LG2 , so the
grease functions are fully utilized.
* Clean grease is exclusively used for clean environments under normal pressure.
