This document is applicable for testing rolling bearing greases, especially of unused grease.

NOTE

Suitable greases are greases of NLGI classes 1 to 3 according to DIN 51818 [ 6 ]. Suitable greases for lubrication of rolling bearings are especially greases according to ISO 12924 . The test method according to this document delivers meaningful results for rolling bearings; however, it can also be applied for greases in similar applications [ 12 ][ 13 ].
