Norchem 761 is a premium grade heavy-duty wire and open gear grease formulated with highly refined mineral base oil, calcium sulfonate complex thickener and varieties of additives including anti-rust, anti-wear, water-resistant properties, and antioxidant for high temperature. It is especially suitable for use in high temperatures, harsh and wet environments.

Features & Benefits:

• Protects against the corrosion effect of either salt or fresh water.
• Excellent adhesion and super tacky. Prevents grease breakdown even in presence of water
• Extraordinary performance at high and low temperatures.
• Lengthens service life and provides an extended safety factor to wire ropes, open gears and equipment.
• Excellent lubrication under heavy loaded gears and wire ropes.

Application:

This grease is particularly well-suited for lubricating wire ropes and open gears in heavy machinery, construction equipment, mining equipment, marine applications, and other industrial settings where extreme conditions are encountered. It helps to reduce friction, wear, and corrosion, thereby extending the life of these components and ensuring smooth operation.
