SH129 Lubricating grease roller stability tester
The SH129 lubricant roller stability tester is applicable to the
standards ASTM D1831 and SH/T0122 "Determination of Lubricant
Roller Stability". When operating this instrument, a certain amount
of sample is used, and after working on the roller testing machine
for 2 hours at room temperature, the working cone penetration of
the lubricant before and after the test is measured. This
instrument is suitable for measuring the viscosity change of
lubricating grease after working on a drum testing machine, in
order to determine the mechanical shear stability of the
lubricating grease.
