CENTRIFUGE SEPARATION CHARACTERISTICS — ASTM
#D4425-84 Centrifuge Test — K36 = 2/24 maximum, very
high resistance to centrifuging.
NLGI GRADE (ASTM D-217) —
1
/
2
CONSISTENCY (ASTM D-217) — 60 stroke worked penetration
value in the range of 315 to 360 measured at 77°F (25°C)
MINIMUM DROPPING POINT — 350°F (177°C) min.
MINIMUM TIMKEN EP O.K. LOAD — 40 lbs (18 kg).
ADDITIVES — Rust and oxidation inhibitors that do not
corrode steel or swell or deteriorate synthetic seals.
Packaging
14 oz. CARTRIDGES — For use in standard industrial
lubrication guns.
35 lb. PAILS — Ideal for larger size couplings or many
smaller sizes.
120 lb. KEG — For plants with many small couplings or large
size couplings. Best for hand packing.
400 lb. DRUMS — For plants with a pressurized lubrication
system.
CASE LOTS — 10 Pak – 14 oz. cartridges, 30 – 14 oz.
cartridges.
General Purpose Grease
ANNUAL LUBRICATION — The following specifications and
lubricants for general purpose grease apply to Falk Steelflex
couplings that are lubricated annually and operate within
ambient temperatures of 0° to 150°F (–18° to 66°C). For
temperatures beyond this range (See Table 1), consult the Factory.
If a coupling leaks grease, is exposed to extreme
temperatures, excessive moisture or experiences frequent
reversals, more frequent lubrication may be required.
Specifications — General Purpose
Coupling Lubricants
The values shown are typical and slight variations are
permissible.
DROPPING POINT — 300°F (149°C) or higher.
CONSISTENCY — NLGI No. 2 with 60 stroke worked
penetration value in the range of 250 to 300.
SEPARATION AND RESISTANCE — Low oil separation rate
and high resistance to separation from centrifuging.
LIQUID CONSTITUENT — Possess good lubricating properties,
equivalent to a high quality, well refined petroleum oil.
INACTIVE — Must not corrode steel or cause swelling or
deterioration of synthetic seals.
CLEAN — Free from foreign inclusions.

INSTALLATION OF TYPE T35 STEELFLEX
TAPERED GRID COUPLINGS
Installation
Only standard mechanics tools, wrenches, a straight edge and
feeler gauges are required to install Falk Steelflex couplings.
Clean all parts using a non-flammable solvent. Check hubs,
shafts and keyways for burrs. Coupling Sizes 1020T thru
1090T are generally furnished for CLEARANCE FIT with
setscrew over the keyway. Sizes 1100T and larger are
furnished for an INTERFERENCE FIT without a setscrew.
CLEARANCE FIT HUBS — Do not heat clearance fit hubs.
Install keys, mount hubs flush with shaft ends or as otherwise
specified and tighten setscrews.
INTERFERENCE FIT HUBS — Furnished without setscrews.
Heat hubs to 275°F (135°C) using an oven, torch, induction
heater or an oil bath. To prevent seal damage DO NOT heat
hubs beyond a maximum temperature of 400°F (205°C).
When an oxy-acetylene or blow torch is used, use an excess
acetylene mixture. Mark hubs near the center of their length in
several places on hub body with a temperature sensitive
crayon, 275°F (135°C) melt temperature. Direct flame towards
hub bore using constant motion to avoid overheating an area.
WARNING:
If an oil bath is used, the oil must have a flash
point of 350°F (177°C) or higher. Do not rest hubs on the
bottom of the container. Do not use an open flame in a
combustible atmosphere or near combustible materials.
Heat hubs as instructed above. Mount hubs as quickly as possible
with hub face flush with shaft end. Allow hubs to cool before
proceeding. Insert setscrews (if required) and tighten.
Maximize Performance & Life
The performance and life of couplings depend largely upon
how you install and maintain them. Before installing
couplings, make certain that foundations of equipment to be
