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.  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 seperation 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, or is exposed to extreme environments, 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)

If Falk LTG grease is not used in coupling use an NLGI EP #2 type grease specific for couplings with rust and oxidation inhibitors that do 
not corrode steel or swell or deteriorate synthetic seals. This applies for general applications where the coupling will operate in ambient 
temperatures of -18º C to 66ºC (0ºF to 150ºF). 
Consult a local lubricant representative for available products  in your area with the required weight and lubricant standard requirements as 
listed below.

11.1.  Lubricate coupling with correct amount of lubricant specified on table 9.

If coupling leaks grease, is exposed to extreme temperatures, excessive moisture or experiences frequent reversals or axial movements; 
more frequent lubrication may be required.

   CAUTION: Remove grease fitting and make certain all plugs are inserted after lubricating.

12.  ANNUAL MAINTENANCE

12.1.  For extreme or unusual operating conditions, check coupling more frequently.

12.2.  Check coupling alignment per steps on page 6. If the maximum operating misalignment values are exceeded, realign the 

coupling to the recommended installation limits. See Table 4, 5, 7 and 8  for installation and operating alignment limits. 

12.3.  Check tightening torques of all fasteners.

12.4.  Inspect seal ring and gasket to determine if replacement is required. If leaking grease, replace.

12.5.  When connected equipment is serviced, disassemble the coupling and inspect for wear. Replace worn parts. Clean grease from 

coupling and repack with new grease. Install coupling using new gasket as instructed in this manual.

Periodic Lubrication
The required frequency of lubrication is directly related to the type of lubricant chosen, and the operating conditions. Steelflex couplings 
lubricated with common industrial lubricants, such as those shown in Table 9, should be relubed annually. The use of Falk Long Term Grease 
(LTG) will allow relube intervals to be extended to beyond five years. When relubing, remove both lube plugs and insert lube fitting. Fill with 
recommended lubricant until an excess appears at the opposite hole.
