SH129 Grease Drum Stability Tester for Grease Mechanical Shear Stability Test ASTM D1831

SH129 Grease Drum Stability Tester for Grease Mechanical Shear Stability Test ASTM D1831

The SH129 Grease Drum Stability Tester meets ASTM D1831 and SH/T 0122, the grease roller‑stability testing specification. For operation, load a defined grease specimen and run a 2‑hour room‑temperature cycle on this drum test unit, then compare the worked penetration values of grease pre‑test and post‑test. Designed to evaluate consistency variation of grease after drum‑type mechanical cycling, this lab equipment evaluates grease resistance to mechanical shear forces.
