Your needs - our lubrication solutions
NORBERT GR AR 555 is a white, homogeneous, long-lasting, high temperature grease. It is based on a perfluoropolyether (PFPE) base oil and thickened with polytetrafluoroethylene (PTFE).
NORBERT GR AR 555 has excellent corrosion protection and evaporative stability, even under high temperature conditions.
Product Applications
NORBERT GR AR 555 has been widely used in many industries for high temperature lubrication points.
Typical applications are.
- Corrugated paper making equipment
- Sealing devices
- Conveying equipment
- Clean room control equipment and semiconductor technology
- Vacuum application equipment
Compatibility with plastic and rubber parts:
Grease consisting of perfluoropolyether as the base oil and PTFE as the thickener is usually neutral to rubber parts and plastic parts (except for fluoroelastomer parts). Even so, we recommend that a compatibility test with the material be conducted before applying the product in bulk.
Precautions for use
To optimize lubrication, we recommend cleaning the friction points first with petroleum solvent 180/210 and then with NORBERT XZ3-1. Then blow off all petroleum solvents with clean, dry compressed air or hot air. For initial lubrication, the friction points must be very clean (free of oil, grease and sweat stains) and free of any dirt.
NORBERT GR AR 555 can be applied to the lubrication points by means of a brush, spatula or greaser. To ensure optimal lubrication, you can consult the various technical sales departments of NORBERT in case of any questions.
The product can also be applied by means of our automatic grease fillers. Please consult Norbert Lubrication's application engineering experts to determine if an automatic grease filler can be used under your process conditions.
