* Typical value

Extreme pressure low temperature grease

SKF LGWM 1 is a low consistency mineral oil based grease, using a lithium soap and containing extreme pressure additives. It is extremely suitable for the lubrication of bearings operating under both radial and axial loads.

Features & benefits

• Good oil film formation at low temperatures down to –30 °C (–20 °F)
• Good pumpability down to low temperatures
• Good corrosion protection
• Good water resistance

Typical applications

• Wind turbine main shafts
• Screw conveyors
• Centralised lubrication systems
• Spherical roller thrust bearing applications
