MAINTENANCE
LUBRICATION REPLACEMENT
If the gear unit is filled with mineral oil, the lubricant should be replaced at least after every 10,000 operating hours or after every two years. If
the gear unit is filled with synthetic oil, the lubricant should be replaced at least after every 20,000 operating hours or after every four years
Often gear reducers are exposed to extreme ambient conditions, hostile environments, wet conditions, or dirty and dusty operating areas.
Especially in these situations, it is important to establish a condition-based oil service interval.
OIL SPECIFICATIONS
NORD supplies aII reducers’ fiIIed with oiI from the factory. Standard lubricant is ISO VG220 mineral-based oil. Consult the sticker adjacent
to the fill plug to determine the type of lubricant installed at the factory. However, some units have special lubricants designed to operate in
certain environments or to extend the service life or service temperature range of the lubricant. If in doubt about which lubricant is needed,
contact NORD Gear.

Food grade lubricants must be in compliance with FDA 212 CFR 178.3570
and qualify as a NSF-H1 lubricant. Please consult with lubrication
manufacture for more information.
When making a lubrication change, check with the lubrication supplier to
assure compatibility and to obtain recommended cleaning or flushing
procedures.
Do not to mix different oils with different additive packages or different base
oil formulation types. Polyglycol (PG) oils are not miscible with other oil
types and should never be mixed with mineral oil.
Please Consult NORD if considering oils of ISO Viscosity VG100 or lower.
