High-
speed

NSK Grease LR3 Reference No. : NSK GRS LR3
Quantity: 80 g Tube color: Green

Feature It contains a special synthetic oil for high temperature and stability, and a carefully selected anti-
Application oxidation agent. This grease dramatically increases lubrication life under high temperature conditions.
It is used for high speed, medium load. Lubrication life exceeded 2 000 hours in the endurance test
at 150ºC. Its rust prevention capacity in severe conditions such as water and moist environments is

further strengthened.

It is a standard grease for ball screws PSS type (shaft dia. 15 mm or over), FSS type and VFA type.
It is ideal for operation with medium load, at high speed such as positioning in high tact material
handling equipment.
