INTRODUCTION
This manual applies to Sizes 1150T thru 1260T and 150T thru
260T Falk SteelfIex Tapered Grid Couplings. Unless otherwise
stated, information for Sizes 1020T thru 1140T applies to Sizes
150T thru 260T respectively, e.g. 1150T = 150T, 1260T =
260T, etc. These couplings are designed to operate in either
the horizontal or vertical position without modification.
The performance and life of the couplings depend largely upon
how you install and service them. Carefully follow the
instructions in this manual for optimum performance and
trouble free service.
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.
LUBE FITTINGS
Cover halves have

NPT Iube holes. Use a standard grease
gun and Iube fitting as instructed on Page 4.
LIMITED END FLOAT
When electric motors, generators, engines, compressors and
other machines are fitted with sleeve or straight roller bearings,
limited axial end float kits are recommended for protecting the
bearings. Falk Steelflex couplings are easily modified to limit
end float; refer to Manual 428-820 for instructions.
LUBRICATION
Adequate lubrication is essential for satisfactory operation.
Page 2 provides a list of typical lubricants and specifications
for general purpose and long term greases. 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 annually.
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 grid-groove area of Steelflex couplings resulting in
premature hub or grid 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. The
consistency of Falk LTG changes with operating conditions. As
manufactured it is an NLGI #1/2 grade. Working of the
lubricant under actual service conditions causes it to become
semifluid while the grease near the seals will set to a heavier
grade, helping to prevent leakage.
LTG is highly resistant to separation, easily out performing all
other lubricants tested. The resistance to separation allows the
lubricant to be used for relatively long periods of time.
Steelflex couplings initially lubricated with LTG will not require
re-lubrication until the connected equipment is stopped for
servicing. If a coupling leaks grease, is exposed to extreme
temperatures, excessive moisture, or experiences frequent
reversals, more frequent lubrication may be required.
Although LTG grease is compatible with most other coupling
greases, the mixing of greases may dilute the benefits of LTG.
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).
CAUTION: Do not use LTG in bearings.
