3. Synthetic Lubricants are recommended for severe service applications. These lubricants are
more stable in regard to viscosity and temperature. They have a longer service life so they
may require fewer oil changes. They also decrease friction and wear on the gear reducer so
they may increase the life of the gear reducer.
4. This synthetic lubrication is also compatible with nitrile seal material as well as with alloy
bronze gear material.
