Nye Lubricants adds more food grade lubricants
The faster food process machinery runs, the more likely it is to benefit from synthetic oils and greases: Nye Lubricants has added more food grade lubricants to their portfolio
The NyeCorr PFPE is completely compatible with other PFPEs currently used in the heated roll bearings of single facers and large 36 inch preheaters.
The NyeCorr 140 PFPE has a base oil viscosity equivalent to an ISO 460 base oil while other PFPEs use only ISO 220 base oil stock.
The NyeCorr higher viscosity base oil provides more load carrying capability and will be able to better withstand the operating temperatures of the single facer application.

Whether you are using an existing PFPE grease or converting from a conventional hydrocarbon oil system, Nye Lubricants can help make the transition easier.
To explain further, below there are a few commonly asked questions about converting to NyeCorr.
Our plant is currently using another more expensive brand of PFPE grease.
CAn we switch to NyeCorr now?.
Answer: Yes.
NyeCorr is a PFPE base oil grease which has the same chemistry as the other, more expensive, PFPE grease.
It is completely compatible with and can be pumped directly over the other PFPE brand.
There is no need to remove the brand "X" PFPE grease, simply start using NyeCorr and save money.
When is the best time to change our single facer oil system over to NyeCorr grease?.
Answer: The best time to convert from hydrocarbon oil or grease to NyeCorr is during the roll change.
What changes need to be made when converting a single facer or pre-heater from an oil system to NyeCorr?.
Answer: C-4 or greater internal bearing clearance is required since bearings tend to run slightly hotter with PFPE type greases.
New bearings should be thoroughly cleaned to remove any rust inhibitors or oils that my have been applied by the bearing manufacturer.
Nye Lubricants can provide you with an effective hydrocarbon solvent for the job, NyeSolv HG.
Pack the new bearings and cavities with NyeCorr before re-installing them into the housing or on the roll shafts.
Finally, after complete assembly and the equipment has reached normal operating temperatures fill the bearings completely with NyeCorr.
Use a pin type or button head grease fitting on all NyeCorr greased bearings and use a dedicated grease gun with the proper mating fitting.
This will prevent the chance of a petroleum or other hydrocarbon grease from being accidentally mixed with NyeCorr.
What are some of the advantages of converting to NyeCorr?.
Answer: NyeCorr grease will improve safety and housekeeping by eliminating the slipping hazards around machinery usually associated with oil systems.
Product quality can be improved because oil will no longer be getting on your corrugated board.
EPA fines are avoided with the removal of oil running down the single facer side frames into sewer drains.
NyeCorr greases were specially formulated for more resistance to high temperature, improved corrosion and wear prevention properties.
This will protect your single facer bearings and reduce downtime over other more expensive PFPE base oil grease.
What solvent can be used to remove PFPEs from housings and other re-ussable single facer parts?.
Answer: Nye Fluorosolvent 504 is completely fluorinated, fast evaporating "ozone-safe" solvent intended as a cleaning solvent for NyeCorr PFPE greases.
