Apps
HP-870 grease can be widely used under conditions such as low or high temperature, corrosive, solvent, liquefied natural gases, high vacuum, etc.
This grease is ideal for use in clean rooms, semiconductor manufacturing equipment, cardboard manufacturing equipment, hot air dryer motor axles, etc. where lubricant evaporation can be problematic.
- Bearings for ovens in the food industry (no contact with food)
- High-temperature aggregates for office and printing equipment, in particular thermal aggregates for laser printers, bearings for heating rolls of laminators, etc.
- Crimped bearings for equipment operating at high temperatures
- Bearings of pressure rollers and gluing edgebanders in the furniture industry
- Bearings for injection molding machines and extruders
- Bearings, seals and other vacuum system assemblies
- Pump bearings for pumping chemically aggressive media
- Oil extraction screw shaft bearings
- Friction units of clean room equipment in the electronics industry, semiconductor manufacturing where lubricant evaporation is undesirable
