and roller bearing grease. It is dark green in colour and has
a smooth, buttery structure. • Temperature range, from -20°C to +150°C
• Formulated to offer robust oxidation stability
SRI Grease 2 is formulated with highly refined base stocks, • Helps protect at high temperatures and speeds
a high performance ashless organic polyurea thickener and
robust anti-rust and anti-oxidation additives. • Provides rust protection as defined by ASTM D5969

Selected specification standards include:

Customer benefits
DIN 51 502 ISO 6743-9
• Designed for use in a wide range of high temperature,
high speed applications helping reduce inventories and Schaeffler
associated costs
• Offers component protection across a wide operating
temperature range, from as low as -20°C up to +150°C
• Formulated to offer reliable long service oxidation
stability, helping improve equipment performance and
protection
• Helps protect components at high temperatures, and
speeds in excess of 10,000 rpm and where salt water
ingress is possible
• Provides rust protection as defined by ASTM D5969
helping provide longer bearing life in high speed, high
temperature operations

Always confirm that the product selected is consistent with the original equipment manufacturer’s recommendation for the equipment operating conditions and
customer’s maintenance practices.
