Lubrication Notes
• Avoid using (EP) gear oils in worm gears that contain
sulfur-phosphorous chemistries, as these additives can
react adversely with bronze worm gears and accelerate
wear.
• Food grade lubricants must be in compliance with FDA 212
CFR 178.3570 and qualify as a NSF-H1 lubricant. Please
consult with lubrication manufacturer for more information.
• When making a lubrication change, check with the
lubrication supplier to assure compatibility and to obtain
recommended cleaning or fl ushing procedures.
• Do not to mix different oils with different additive pack-
ages or different base oil formulation types. Polyglycol (PG)
oils are not miscible with other oil types and should never
be mixed with mineral oil or polyalphaolefi n (PAO)
synthetic
oil.

IMPORTANT NOTES
• The “Ambient Temperature” is intended to be an operation guideline based upon the typical properties of all the
lubricant. The viscosity and other properties of the lubricant change based upon load, speed, ambient conditions, and
reducer operating temperatures. The user should consult with their lubrication supplier & NORD gear before considering
changes in oil type or viscosity.
• To prevent reducer overheating, observe the maximum operating oil temperature limits:
Mineral Oil: 80-85 ºC (176 – 180 ºF).
Synthetic Oil: 105 ºC (225 ºF).
• In the following instances, please consult NORD for specifi c recommendations:
√ Gear units will operate in high ambient temperature conditions exceeding 40 ºC (104 ºF).
√ Gear units will operate in cold ambient temperature conditions approaching 0 ºC (32 ºF) or lower.
√ Lower than an ISO VG100 viscosity oil is being considered for a cold-temperature service.
√ Fluid grease is required for lubricating the gear unit.
• Observe the general lubrication guidelines outlined in user manual U10750.
