ASTM D1831 Lubricating Grease Roll Stability Tester Stainless Steel Roller

# SH129 Lubricating Grease Roll‑Stability Tester

**Compliant with ASTM D1831 & SH/T 0122**

## Product Description

The SH129 Lubricating Grease Roll‑Stability Tester is built in accordance with ASTM D1831 and SH/T 0122 standards. A prescribed amount of grease sample is loaded into the test drum and subjected to a 2‑hour test run at ambient temperature. The worked cone penetration of the lubricating grease is measured before and after the test procedure.

This instrument evaluates consistency changes of lubricating grease induced by mechanical shear inside the test drum, so as to characterize the mechanical shear‑stability performance of test greases.
