Quality requirements
Use a high quality turbine oil with rust and oxidation inhibitors.
You can use an oil of ISO viscosity grade VG 220 (SAE grade 50W) for all bearing operation

Precautions
NOTICE:
• Never mix greases of different consistencies (NLGI 1 or 3 with NLGI 2) or with different
thickeners. For example, never mix a lithium-based grease with a polyurea-based grease.
Doing so may result in decreased performance.
• Remove the bearings and old grease if you need to change the grease type or
consistency. Failure to do so may result in equipment damage or decreased performance.
