• Ability to meet bearing OEM requirements — Suitable for high rpm operations, operating temperatures ranging from -34°C to 204°C (-30°F to 400°F) and offers excellent rust protection in the presence of both salt and fresh water.
• Excellent oxidation stability — Provides excellent bearing life with continuous service possible at temperatures up to 160°C (320°F). For short exposure, the maximum is 200°C (392°F).
• Corrosion protection — Provides superior water resistance and protection of bearings against rust and corrosion.
• Good low shear stability — Will not soften excessively under prolonged low shear stress.

Texaco Polystar RB 2 is a high temperature ball and roller bearing grease.

It is formulated with high quality base stocks, a synthetic polyurea ashless organic thickener, and high performance rust and oxidation inhibitors (the latter to provide superior rust protection in severe applications).

Texaco Polystar RB 2 is specifically designed to meet the factory-fill performance requirements of the major manufacturers of rolling element bearings.

Texaco Polystar RB 2 is recommended:

• For use in antifriction bearings operating at high speeds (speeds up to 500,000 DN).
• Where the operating temperatures are on the order of 150°C (302°F) and higher.
• Where there is a likelihood that water or salt water will get into the bearings.

Typical test data are average values only. Minor variations which do not affect product performance are to be expected in normal manufacturing.

Notes:

1. Minimum operating temperature is the lowest temperature at which a grease, already in place, could be expected to provide lubrication. Most greases cannot be pumped at these minimum temperatures.
2. Maximum operating temperature is the highest temperature at which the grease could be used with frequent (daily) relubrication.
3. Determined on mineral oil extracted by vacuum filtration.
