Product Description
Mobil SHC Grease 460 WT is a supreme performance product especially suited to
exceed the demanding requirements of wind turbine applications at extremes of
temperature. The unique features of synthetic base fluids are combined with
those of a high quality lithium complex thickener. The wax-free nature of
synthetic fluids and the low coefficient of traction provide excellent low
temperature pumpability and very low starting and running torque. The lithium
complex thickener contributes excellent adhesion, structural stability and
resistance to water. The grease has a high level of chemical stability and is
formulated with special additive combinations to provide excellent protection
against wear, rust and corrosion at high and low temperatures.
Mobil SHC Grease 460 WT is specially formulated to lubricate yaw, pitch and
main bearings of wind turbines and has become the first fill product of choice
for many wind turbine builders and component suppliers. The reputation is
based on its exceptional quality and reliability and has proven outstanding
performance in more than 10,000 wind turbines worldwide.
Features and Benefits
The Mobil SHC brand of oils and greases are recognized and appreciated around
the world for their innovation and outstanding performance. A key factor in
the development of ExxonMobil´s products were the close contacts with key
Original Equipment Manufacturers (OEMs) to ensure that our product offerings
would provide exceptional performance in the continually evolving industrial
equipment designs.
Our work with equipment builders has helped confirm the results from our own
laboratory tests showing the exceptional performance of Mobil SHC Grease 460
WT. Compared to conventional greases the benefits of this synthetic grease
include longer grease life, enhanced false brinelling protection and bearing
life, wide temperature range of application, and the potential for improved
mechanical efficiency.
To combat severe application conditions proprietary synthetic base oils have
been chosen for Mobil SHC Grease 460 WT because of their outstanding
thermal/oxidative resistance potential. A state-of-the-art lithium complex
thickener technology and specific additives help to enhance the performance of
Mobil SHC Grease 460 WT offering the following features and benefits:
