Greases for Corrugators
Product Information
Krytox™ PFPE/PTFE greases have become the corrugator
industry standard for lubricating bearings on heatedrolls in single facers and associated equipment. Krytox™
lubricants help eliminate bearing lubrication as a cause ofpremature corrugator roll failure. Corrugator roll changes are
significantly easier and quicker on single facers lubricatedwith Krytox™ greases.

Corrugators choose Krytox™ lubricants for manyreasons:• Most productive lubrication system for single facer
bearings among all paper corrugating plants, equipment
OEMs, and corrugator roll rebuilders• Most thermally stable H-1 base oil available• Reduced risk of bearing failure• Conversion support and PFPE lubrication/application
training available
Krytox greases for the corrugating industry include:™

Krytox™ Corrugator (CORR) 226FG, 227FG Greases—
The standard in PFPE/PTFE greases, recognized byOEMs and operators alike as the premium performing hightemperature grease. These products are NSF H-1 food grade
registered, providing safe, non-toxic, and inert performance infood-related operations.

Safe HandlingFor detailed information, refer to the SDS for the specificgrade of Krytox™ fluorinated grease that you are using.
Highlights are:• When handling, wear any type of impervious rubber gloves.
• Wash hands after use.
• Do not smoke tobacco that may have been contaminatedwith Krytox™ grease. Inhalation of fumes from burning

Krytox™ grease may cause a temporary flu-like illness withsymptoms such as fever, chills, and sometimes cough.
Symptoms are typically gone after 1–2 days.
• When handling Krytox™ solvent or HC cleaner, use adequateventilation, and wear eye protection and any type ofimpervious rubber gloves.

Key Points• Make sure the bearings are clean and free of preservatives,hydrocarbon oils, greases, and residues before lubricatingwith Krytox™ grease; use Krytox™ HC Plus Cleaner or
equivalent. Contaminating Krytox™ grease with any otherlubricant will impair its lubricating value.
• If using pails versus cartridges, slight pooling of oil on top of
the Krytox™ grease can occur, particularly if it has been sitting
unused for a while. Simply mix it back in with a clean stirrer.
• Use special grease fittings—pin or button head—for Krytox™
grease to prevent contamination with hydrocarbon orsynthetic lubricants.

• Use a dedicated grease gun (labeled Krytox™ grease only)with a swivel coupling matched to the special pin or button
head grease fittings (bearing inlet ports). Fill the bearingsand bearing housings completely to prevent air pockets
that can collect water and debris.
• Prevent corrugating process materials (e.g., waxes andpaper debris) from entering the bearings.

Relubrication• Wipe the inlet fittings clean with a clean cloth to prevent
contamination of the Krytox™ grease.
• Add/replenish Krytox™ grease every three months. Pump
about 1 lb (1/2 cartridge), or whatever is necessary, ofKrytox™ grease into the bearing pin or button head grease
fittings to force some existing grease out through theseals. It is best to rotate bearings while adding grease toprevent “channeling” of the new grease through the bearing.
A more conservative approach is to follow this practicemore frequently, say once a month; proportionately lessKrytox™ grease would be needed. Pay attention to plantsafety procedures when working with moving equipment.
• Compare expelled/purged grease with the “Color Guide”
and service as noted. (This guide applies to normal wear
only; contaminants will alter the grease’s appearance.)• Wipe off excess Krytox™ grease from equipment surfaces
to prevent buildup of dirt/debris attracted to surface
grease.

Disposal and Storage• Properly dispose of used Krytox™ grease purged fromoutlet ports, seals, and/or shaft-bearing clearances
according to local, state, and federal codes.
• Keep all Krytox™ grease containers covered to prevent
contamination.
