INTRODUCTION

This manual applies to Sizes 1020T thru 1140T and 20T thru
140T10 Falk SteelfIex Tapered Grid Couplings. Unless
otherwise stated, information for Sizes 1020T thru 1140T
applies to Sizes 20T thru 140T respectively, e.g. 1020T =
20T, 1100T = 100T, etc. These couplings are designed to
operate in either the horizontal or vertical position without
modification. Beginning in year 1994 through 2003, these
couplings were being supplied with one set of inch series
fasteners and one set of Metric fasteners. Beginning in year
2004 only Metric fasteners are being supplied. Refer to Page
6 for part interchangeability.

The performance and life of the couplings depend largely
upon how you install and service them.

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. Sizes 1020T to 1090T10 are furnished with a
pre-measured amount of grease for each coupling. The
grease can be ordered for larger size couplings.

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).
