PRODUCT DESCRIPTION
NYTRON CALTECH XV/EP is calcium sulfonate complex grease especially developed for the steel industry. It is formulated to be used for high temperature lubrication of plain and rolling bearings exposed to heavy loads in the presence of water. Due to its unique thickener’s nature, it shows excellent anti-rust properties and outstanding resistance against water washout.NYTRON CALTECH XV/EP is specifically designed for use in the steel, iron and metallurgical as well as maritime industries. It is particulary suitable for use in bearings under heavy loads & vibrations with medium & low rotation speed, exposed to high temperature and in contact with water requiring anti-corrosive action. Its application temperature range is from -20°C to +200°C.
Properties
- Superior anti-rust and anti-wear properties.
- Extreme water washout performance.
- Excellent mechanical stability even in presence of plenty of water.
- Very high dropping point (>300°C).
- Exceptional load carrying properties (four ball welding load >500 kg).
- Very good adhesiveness to metal surfaces.
- Easy pumpability by centralized automatic lubrication systems.
- Shows sealing effect under wet and muddy environment.
- Contributes to longer bearing life
