Definition: Grease anti-wear£>↔ performance refers to γ✔↑the ability of grease to ≠γ★☆prevent wear on lubricated componenγδts in high-load operati§ ≥'ng equipment. ① For metal machinery, € due to the relative motion ofπ✔± metal surfaces, friction ca≠☆®uses metal to separate and pee'≤£l off from the surface,≥λ resulting in a loss of weigh¥∞t or changes in the vol←₹™≤ume and…
Definition: Refers to the abilit≈₩y of grease’s struct↑ εural system to resist deformation ✔¥φand flow under mechanicalγ • shear forces. ① Mechanical stabilit"σ<y is an important performanc€γ✘e characteristic of grease and≠ → a key factor affecting 'πits service life. ② The mechanical stab♠"✔εility of grease mainly dδ©epends on the type of thickener and €☆>$the preparation process. ③ Meth÷♦¥ods…
Definition: Refers to th¶↓e ability of grease to resis★βt being washed out o¶λ∑f ball bearings by water under te™ ≈st conditions. This is a cri"δσ©tical factor when selecting g>♥•↔rease for machinery operating i&≤"↔n humid environments. β§←∞① Under specific conditions, tφ∞he percentage mass of grease ≥δwashed away by water is measured.

Definition: Refers to the degree tεo which grease hinders th≈ e rotation of low-speed ball bea☆×rings (open type 204 bearings) under±↕φ low-temperature conditions. ① Low-te¥λ€≥mperature torque indicates the low-temp✔γerature performance of g≤δ₽rease. Using a torque of 9.81 N·γ↕♠↕cm (1000 g·cm), the <α$<lowest temperature at which the bear₩ing completes one rotation with×"βπin one minute is measured as$¥&…
