HELICAL & BEVEL REDUCER LUBRICATION

RETAIN FOR FUTURE USE

U10750 - 1 of 2

1. Importance of proper lubrication

Proper gearbox lubrication is essential in order to reduce

friction, heat, and component wear. Lubricants reduce heat

and wear by inserting a protective “ﬂ uid boundary” between

mating parts and preventing direct metal to metal contact.

Lubricants also help prevent corrosion and oxidation, mini-

mize foam, improve heat transfer, optimize reducer efﬁ ciency,

absorb shock loads and reduce noise.

Most NORD reducers are shipped from the factory with a

pre-determined oil ﬁ Il level in accordance to the speciﬁ ed

reducer size and mounting position.

2. Standard oil type

The following tables indicate the standard oil ﬁ ll type used.

Please see user manual U11000 for more speciﬁ c information

and for optional helical and bevel gear lubricants:

SK320

IMPORTANT NOTE

Maintenance-free units are supplied as sealed units with no

vent-plug. Consult NORD prior to ordering if interested in

ordering any of the above sizes as serviceable gear units.

IMPORTANT NOTE

Consult the sticker adjacent to the ﬁ ll plug to determine

the type of lubricant installed at the factory. Some units

have special lubricants designed to operate in certain

environments or intended to extend the service life or

service temperature range of the lubricant. If in doubt

about which lubricant is needed for a certain applica-

tion, please contact NORD Gear.

3. Lubrication replacement

If the gear unit is ﬁ lled 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 ﬁ lled 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 estab-

lish a condition-based oil service interval.

4. Oil viscosity

Viscosity, or the oil’s resistance to shear under load, is often

considered the single most important property of any gear oil.
• Often one will consider making a viscosity correction to

the oil to improve the performance when operating the

gear unit at low temperature or high temperature.
• In cases of extreme load conditions, gear pairs and antifric-

tion bearings may be more susceptible to sliding or scufﬁ ng

wear. In these operating conditions, it may also be ben-

eﬁ cial to consider an increased lubrication viscosity and/or

a lubrication with improved antiwear additive packages.

IMPORTANT NOTE

The user should consult with their primary lubrication

supplier before considering changes in oil type or viscosity.

5. Maximum oil sump temperature limit

To prevent reducer overheating, the reducer’s maximum oil

sump temperature limit must not be exceeded for prolonged

periods of operation (up to 3 hours continuous operation

depending upon reducer size).

Oil Type

Maximum Oil Temperature Limit
NORD

AGMA 9005-D94

IMPORTANT NOTE

Use caution when specifying gear reducers for high tem-

perature service.

If there is concern about exceeding the

allowable safe operating temperatures, please consult

NORD to discuss alternatives.
