Water resistance testing

Definition: Refers to the ability of grease to res₽↔∞♥ist being washed out oβλ f ball bearings by water under t¥→±€est conditions. This is a critica™λ>£l factor when selecting grease for mach ≠$inery operating in humid environmen•βts.

① Under specific conditions, the percαβentage mass of grease washed awa™™¶ y by water is measured. The smalle®≈≠☆r the loss, the less the performanc→←e changes upon water exposure. Ω£Such grease exhibits better ¥≠water resistance, making it more ef±←≠©fective for sealing a★βnd protective applications. This ✔&→πis one of the most important ind ↕icators of grease<♦∑217;s sealing and prot✔₹¥‍ective properties.
