MAINTENANCE
Mineral lubricant should be changed every 10,000 service hours or after two years. For synthetic oils, the lube should be changed every
20,000 service hours or after four years. In case of extreme operating (e.g. high humidity, aggressive environment or large temperature
variations), shorter intervals between changes are recommended.
OIL SPECIFICATIONS
NORD supplies aII reducers fiIIed with oiI from the factory. Consult the sticker adjacent to the fill plug to determine the type of lubricant
installed at the factory. Standard lubricant is ISO VG680 synthetic-based oil. However, some units have special lubricants designed to
operate in certain environments or to extend the service life of the lubricant. If in doubt about which lubricant is needed, contact NORD Gear.
WARNING FOR CONVEYOR APPLICATIONS USING WORM GEARBOXES
Conveyor applications using platic or rubber belts create a
static electric load
which can create an electro chemical process in the worm
gearbox. Using Poly Alkylene Glycol (PAG) oils can lead to a bronze plating process and extreme wear of the worm wheel. Proper electrical
grounding of the conveyor will resolve this issue. Or, if using a different oil is easier, filling the gearbox with a Poly Alpha Olefin (PAO) oil will
also work.
ALL WORM REDUCERS
Worm units have a combination of hard and soft gears. SIiding action of worm gears require a higher viscosity oiI. These units are furnished
with synthetic oiI as standard.
CAUTION: Do not mix mineraI based and synthetic oiIs
.
