Detailed description

Overview:

Great Wall 7028 Aircraft Wheel Grease is formulated from synthetic oil thickened with an organic thickener and refined with various additives, including antioxidants, anti-corrosion agents, and rust inhibitors.

Performance characteristics:

◎ Excellent high and low temperature performance ensures normal bearing operation over a wide temperature range.

◎ Excellent rust and protective properties effectively protect the bearing's metal components from external corrosion.

◎ Good lubricity ensures proper bearing lubrication and reduces bearing wear.

◎ Excellent storage stability ensures normal product use.

◎ Excellent impact load resistance effectively protects bearings from accidental overloads.

◎ Excellent rubber compatibility, compatible with most rubbers.

Recommended:

Suitable for lubrication and sealing of aircraft wheel bearings, aircraft engine accessories, and rubber components in sealing systems.

Applicable temperature range: -40°C to 150°C, temporarily up to 180°C.

Execution standard:

GJB 1239-91
