Lubrication
ALL standard reducers ordered from Factory are filled with Mobil Glygoyle 460 Polyglycol (PAG) lubricant or equivanent suitable continuous duty option
with a -10°F to 120°F ambient temperature range. Lubrication quantities are specified in Table 1 for various mounting positions. Prior to startup, verify that
the mounting position on nameplate matches required position (see Fig. 1). LeCentric™ reducers are filled to proper amount of oil based on mounting
position printed on nameplate.
All LeCentric™ Gear Reducers will be filled with oil for position “H3” unless otherwise specified. If the ambient temperature will
be outside the range for the lubricant installed at the factory, drain and refill the reducer with the proper viscosity lubricant prior to use. Consult the Factory
for alternate lubricants .
Change Intervals: LeCentric™ units utilize extreme pressure lubricants which protect the teeth in the event of the oil thinning out due to local temperature
rise, or high pressure due to accidental overloads. LeCentric™ reducers are “lubed-for-life” and do not require regular oil changes under normal industrial
operating conditions and environments if the reducers are operated in severe environments (i.e. high or low temperatures, high altitudes, dusty, caustic,
etc.) oil changes may be required.
Do not mix different oils in the reducer. Oils should be compatible with Viton® seal material.
Oil should be changed/checked if reducer is used in severe environment.
In the Food and Drug Industry (including animal food), consult the lubricants which are acceptable to the Food and Drug Administration
and for other authorative bodies having jurisdiction. Factory supplied PAG oil is acceptable for incidental food contact (NSF H1) for use in and around food
processing areas .
