Your needs - our lubrication solutions
NORBERT GHY 72's outstanding product performance is due to its optimized product composition (including: ester oils, polyurea thickeners and special additives) and extremely clean manufacturing environment. This ensures the outstanding characteristics of NORBERT GHY 72 in rolling bearing applications:
high purity
Low noise
long shelf life
Excellent water resistance
Excellent corrosion resistance
Product application
The NORBERT GHY 72 is particularly suitable for bearing applications that require long-term or lifetime lubrication over a wide operating temperature range, such as ball bearings in industrial motors, fans, air conditioners, automotive generators, computers, CD drives, and home appliances and office equipment.
Precautions for use
The NORBERT GHY 72 can be greased by means of a brush, scraper, grease gun or grease cartridge. If using a centralized automatic lubrication system, we recommend testing the NORBERT GHY 72 for pumpability in the system before use (it is recommended to refill the grease within 2 months after receiving it). The typical characteristic of polyurea grease is curing after long-term storage. This increase in consistency usually does not affect the performance of the grease in use and can be restored by shearing or agitation.
Compatibility with rubber and plastic parts
NORBERT GHY 72 has been statically tested for compatibility. We recommend testing the grease for compatibility with related materials before batch application.
