Thames Ultra Heavy Grease 89 is a premium grease designed to protect and lubricate heavy-duty bearings operated at a wide range of speeds in moist operating condition. It is formulated with mixed-base multi-complex thickener and a package of advanced additives to offer exceptional loadcarrying properties, excellent corrosion protection and water washout resistance over a wide range of temperatures. This grease is highly recommended, ultimately, to prolong the service lives of bearings and other greaselubricated components of heavy-duty machineries/equipment in industries such as agriculture, cement, construction, mining, quarrying, etc.


EXCEPTIONAL LOAD-CARRYING CAPABILITY: Quality designed to outperform all conventional EP (Extreme Pressure) greases, Thames 89 is formulated with an innovative mixed-base multi-complex thickener with outstanding EP performance. Based upon a mixture of lithium and calcium metal soaps processed with complexing agents, this special thickener offers outstanding lubricity, anti-wear property and load-carrying capability. The EP performance of Omega 89 is further enhanced by the addition of an advanced EP additive. To evaluate the EP performance of lubricating greases, a generally accepted test called “Four Ball (4-ball) Weld Load” test is used. Typically, greases with rating of over 250 kgf in the 4-ball weld load test can be classified as EP greases. Omega 89 out-performs the conventional EP greases by over three times with a rating of not less than 800 kgf. In the market, this exceptional rating is unmatched by 95% of the EP greases without the use of solid additives.
