INTRODUCTION
This manual applies to standard coupling Types GL32 with
exposed bolts. For couplings furnished with special features,
refer to assembly drawing furnished with coupling for proper
assembly arrangement and any additional installation or
maintenance requirements. Type GL32 couplings are
recommended for applications that require axial hub
movement and are designed for horizontal operations. Refer to
Factory for vertical applications.
CAUTION: Consult applicable local and national safety codes
for proper guarding of rotating members. Observe all safety
rules when installing or servicing couplings.
WARNING: Lockout starting switch of prime mover and remove all
external loads from drive before installing or servicing couplings.

LUBRICATION
Adequate lubrication is essential for satisfactory operation. Because
of its superior lubricating characteristics and low centrifuge
properties, Falk Long Term Grease (LTG) is highly recommended.
The use of general purpose grease requires re-lubrication of
the coupling at least every six months. If coupling leaks grease,
is exposed to extreme temperatures, excessive moisture,
experiences frequent reversals or axial movements; more
frequent lubrication may be required.
USDA Approval
LTG has the United States Department of Agriculture Food Safety
& Inspection Service approval for applications where there is no
possibility of contact with edible products. (H-2 ratings).
Long Term Grease (LTG)
The high centrifugal forces encountered in couplings separate the
base oil and thickener of general purpose greases. Heavy
thickener, which has no lubrication qualities, accumulates in the
tooth mesh area of gear couplings resulting in premature mesh
failure unless periodic lubrication cycles are maintained.
Falk Long Term Grease (LTG) was developed specifically for
couplings. It resists separation of the oil and thickener and is
an extreme pressure grease.
Gear couplings initially lubricated with Falk Long Term Grease
(LTG) will not require re-lubrication for up to three years.
Although LTG grease is compatible with most other coupling
greases, the mixing of greases may dilute the benefits of LTG.
CAUTION: Do not use LTG in bearings. Do not use LTG for
low speed applications. Refer to Table 4 for coupling speed
range of LTG grease.
