IMPORTANT NOTES
• Observe the general lubrication guidelines in User Manual U10800.
• Ambient temperature range is a guideline only. The allowed operating temperature range for the gear unit is depen-
dent upon assembly components used, their individual temperature limits, and the actual operating conditions.
• The selected oil type and viscosity is considered appropriate for most applications utilizing the specified NORD gear unit
type. Different oil types or viscosity grades may be recommended if the gear unit is exposed to frequent high load
conditions or operating under extreme low or high ambient temperature conditions.
• To prevent reducer overheating, observe the maximum operating oil temperature limits:
Synthetic oil: 105 ºC (225 ºF).
• Consult NORD for recommendations in the following instances:
√ The gear unit is exposed to frequent high load conditions.
√ Ambient temperature conditions exceed 40 ºC (104 ºF) or approach 0 ºC (32 ºF) or lower.
√ Fluid grease is being considered or specified for lubricating the gear unit.
√ Lower than an ISO VG100 viscosity oil is being considered for a cold-temperature service.
WARNING
• 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 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 or polyaolpha-
olefin (PAO) oils.
