OBERON G27 

OBERON G27 HEAVY DUTY INDUSTRIAL CALCIUM SULFONATE GREASE FOR EXTREME PRESSURE PROTECTION 

DESCRIPTION Oberon G27, is a state-of-the-art product, which is characterized by exceptional mechanical stability. The very high load carrying ability, excellent resistance to water, oxidation and corrosion, and outstanding performance in a wide temperature range, makes it a high performance grease. It contains no heavy metals or other harmful or environmentally undesirable additives, such as phosphorous, chlorine, zinc, phenols, antimony, barium or lead.

PERFORMANCE
Mechanical Stability Tests in the ASTM grease worker show virtually no change in consistency after 100,000 strokes, in addition, no significant change was observed in the Conventional Roll Test (D.1832). The Shell Roll test modified from 6 hours at room temperature to 100 hours at 150 deg F, to increase the severity and again no softening was observed.

Load Carrying Ability
Timken Values at 65lbs. OK Load, LWI of 65kg are typical of Oberon G27. Four Ball Wear Tests (D.2266) also demonstrate the excellent lubricity of this product.

Thermal Stability
1. Dropping Point – Oberon G27 will not become pourable until temperatures approaching 600 deg F is reached. After cooling to room temperature, it turns to its original grease structure, unlike some lithium complex, polyurea, calcium complex and clay greases.

2. Wheel bearing Leakage – (D.1263) In this test, modified at 325 deg F, Oberon G27 showed no leakage, hardening or other signs of failure and is comparable to other premium greases.

3. Oxidation Stability – Bomb oxidation stability tests (D.942) produced pressure drops of only 2 PSI after 500 hours and 9 PSI after 1,000 hours. These values reflect the excellent resistance of Oberon G27 to oxidation.

4. Resistance to Water
4.1 In a variation of the ASTM work stability test, Oberon G27 was mixed with 50% water and after working 100,000 strokes, remained virtually unchanged in consistency. Other premium greases run in this test tend to slump or break down.

4.2 Water Resistance – Oberon G27 has exhibited excellent adhesion, high water absorption and no sign of breakdown.

4.3 Water Washout (D.1264) Oberon G27 compares favorably to other greases in this test.

CORROSION RESISTANCE
In the Rust Test Rating (D.1743) Oberon G27 passes this test and is equivalent to other premium greases. In a more severe version of this test, modified with synthetic sea water, Oberon G27 still gives a 1,1,1 rating.
