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°F to 150°F (-18°C 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.

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.

INSTALLATION OF TYPE T10 STEELFLEX

TAPERED GRID COUPLINGS

Installation

Only standard mechanics tools, wrenches, a straight edge and
feeler gauges are required to install Falk Steelflex couplings.
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 — Clean all parts using a non-
flammable solvent. Check hubs, shafts and keyways for burrs.
Do not heat clearance fit hubs. Install keys, mount hubs with
flange face flush with shaft ends or as otherwise specified and
tighten setscrews.

INTERFERENCE FIT HUBS — Furnished without setscrews.
Heat hubs to a maximum of 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.
