Black Pearl SRI 2
High performance high temperature polyurea grease
Black Pearl™ SRI 2 is a high performance, high temperature ball and roller grease, designed for use in a wide range of automotive and industrial applications across a wide temperature range.
Applications
Black Pearl SRI 2 is recommended:
- for use in a wide range of automotive and industrial applications
- for use in antifriction bearings operating at high speeds (10,000 rpm and greater)
- 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 Black Pearl SRI 2 will perform in bearings at temperatures as low as -30°C
- Under normal operating temperatures and conditions, Black Pearl SRI 2 can be used as a “Life Pack” lubricant in sealed bearings
Note that in today’s more modern, high output (horsepower), high load electric motors, there are times where these units employ ball bearings and roller element bearings on the same motor. On units where horsepower and load are considered high on the roller element bearing, EP greases should be employed.
