NSK Grease Low- Light-
temperature load

NSK Grease PS2 Reference no. : NSK GRS PS2
Quantity: 80 g Tube color: Orange

Feature The major base oil component is synthetic oil with mineral oil. It is an excellent lubrication especially for
low temperature operation. It is for high speed and light load.

Application It is a standard grease for NSK miniature linear guides and ball screws. It is especially superb for
low temperature operation, but also functions well in normal temperatures, making it ideal for small
equipment with light load.
