Lubrication Recommendations
INTRODUCTION
Carefully follow instructions on the drive nameplate,
warning tags and installation manuals furnished with the
drive.
Lubricants listed in this manual are typical products
ONLY and should not be construed as exclusive
recommendations. Industrial type petroleum-based rust
and oxidation inhibited (R & O), industrial type extreme
pressure (EP) or industrial type micropitting resistant gear
lubricants are the recommended gear lubricants. They can
be formulated using petroleum or synthetic base stocks.
The section on food grade lubricants provides guidance
selecting lubricants for applications needing this class of
lubricants. Food grade lubricants are formulated using
petroleum or different types of synthetic base stocks.
LUBRICANT SELECTION PROCESS
1. Refer to Table 3 or 4 for proper lubricant viscosity
grade based on ambient temperature range. See Falk
GMax 6000 paragraph on this page for ambient air
temperature range if using this lubricant.
2. Refer to Table 1 for summary of lubricant type.
3. Using proper lubricant table and viscosity grade,
select desired lubricant manufacturer name.
4. Refer to Table 2 for approximate oil capacity to
purchase.
SYNTHETIC LUBRICANTS (TABLES 6A, 6B & 6C) —
Synthetic lubricants of the polyalphaolefin (PAO) type
are recommended for cold climate operation, high
temperature applications, extended temperature range
(all season) operation and/or extended lubricant change
intervals. The proper viscosity grade of synthetic lubricant
is given in Table 4.
Polyalkylene glycols (PAG) are another class of synthetic
lubricants. They have similar performance properties
as PAO synthetics — low pour point, stable at elevated
temperatures, and high viscosity index. PAG's have
exceptional tolerance to water contamination.
WARNING: Polyalkylene glycols (PAG’s) are not
compatible with petroleum mineral oil or PAO synthetic
lubricants and must not be topped off with either lubricant.
In addition, petroleum mineral oils or PAO synthetic
lubricants must not be used to top off systems containing
PAG’s. Do not use PAG’s in gear drives with painted interior
housing walls unless paint compatibility is checked.
Compatibility with oil seals and gasket materials must be
checked prior to use. PAG lubricants are not compatible
with polycarbonate sight glass. Use glass sight glass.
Falk GMax 6000 — Rexnord markets Falk GMax 6000, a
polyalkylene glycol lubricant. It is available in ISO VG 135
and covers ambient air temperature range -30° to +125°F
(-34° to +52°C). Gear drives equipped with internal
backstop can use GMax in ambient temperatures above
-20°F (-29°C).
WARNING: GMax 6000 is not compatible with petroleum
mineral oil or PAO synthetic lubricants and must not be
topped off with either lubricant. In addition, petroleum
mineral oils or PAO synthetic lubricants must not be used
to top off systems containing GMax 6000. Do not use
GMax 6000 in gear drives with painted interior housing
walls unless paint compatibility is checked. Compatibility
with oil seals and gasket materials must be checked prior
to use. GMax 6000 is not compatible with polycarbonate
sight glass. Use glass sight glass.
ANTI-WEAR (AW) LUBRICANTS — For moderately
loaded gear drives or operating conditions challenging
for conventional R & O oils, industrial type anti-wear (AW)
lubricants are suggested. These lubricants contain anti-
wear additives that provide stronger thicker lubricant film
to help maintain surface separation. Synthetic lubricants
by inherent nature of base stock properties provide anti-
wear performance.
EXTREME PRESSURE (EP) LUBRICANTS (TABLES 5B
& 6B)
— For highly loaded drives or for drives loaded in
excess of original estimates, industrial-type petroleum EP
lubricants are preferred. EP lubricants are manufactured
from petroleum or synthetic base lubricants. Anti-scuff is
another term used to describe EP lubricants.
CAUTION: EP LUBRICANTS & INTERNAL BACKSTOPS
—
Do not use EP lubricants or lubricant formulations
including sulfur-phosphorus (EP), chlorine, lead
derivatives, graphite or molybdenum disulfides in drives
equipped with internal cartridge type backstops. Lubricant
formulations may change over time. Some lubricants in
Tables 5A & 6A may contain higher amounts of additives
to reduce friction, resulting in lubricant properties

VISCOSITY (IMPORTANT)
The proper viscosity grade for petroleum-based lubricant
is found in Table 3. For synthetic lubricant viscosity grades,
refer to Table 4 and the “Synthetic Lubricants” paragraphs.
Viscosity grade is determined by ambient air temperature
in immediate vicinity of gear drive. Lubricant selections
must have a pour point at least 10°F (5.5°C) below the
expected minimum ambient starting temperature.
LUBRICANT TYPES
PETROLEUM-BASED LUBRICANTS (TABLEs 5A, 5B &
5C) — Industrial type petroleum-based rust and oxidation
inhibited (R & O) gear lubricants are the most common and
readily available general purpose gear lubricants.
