Rail Damping Grease High-Viscosity Polymer High-Adhesion, for Rail Transit Damping Shock Absorption Guide Silencing
This rail damping grease is a high‑viscosity special polymer‑modified lubricating grease formulated with base oil, polymer tackifier and dedicated thickener together with anti‑oxidant, anti‑wear and anti‑corrosion additives. It features exceptional surface adhesion and stable viscoelastic damping performance under persistent vibration and reciprocating sliding. The grease absorbs mechanical shock energy, reduces friction‑induced noise, and delivers durable damping, shock‑absorption and silencing
Product DetailsRail Damping Grease High‑Viscosity Polymer High‑Adhesion, for Rail Transit Damping Shock Absorption Guide SilencingThis rail damping grease is compounded with refined base fluid, proprietary viscoelastic thickener and high‑molecular polymer tackifying agent, combined with anti‑wear, anti‑oxidant and corrosion‑inhibiting additives. The incorporated high‑viscosity polymer component significantly improves the grease’s surface‑adhesion property. It strongly resists grease throwing‑off caused by continuous high‑frequency vibration, which frequently occurs during rail transit operation. The stable viscoelastic matrix maintains consistent damping characteristics under fluctuating service temperatures.
When applied on rail transit sliding guides, pivot joints and moving contact interfaces, the grease forms a thick, tenacious viscoelastic lubricating film. This viscous layer dissipates impulse vibration energy generated during vehicle starting, braking and travelling. It mitigates metal‑to‑metal knocking and sliding friction noise, realizing effective shock‑absorption and silencing for guide movement assemblies. Reliable damping torque reduces clearance‑related rattling of movable mechanical parts.
Under long‑term reciprocating sliding and sustained intense mechanical vibration, the grease internal structure exhibits excellent anti‑shearing stability and inhibits oil separation. The antioxidant additive system slows thermal‑oxidative ageing of base oil, extending the service interval for on‑site maintenance. Anti‑corrosion ingredients provide reliable protection for metallic guide substrates against humid air and occasional rainwater splashing in open or semi‑open rail transit operating environments.
It is suitable for maintenance lubrication of rail transit sliding guides, hinge assemblies, positioning pivot points and related vibration‑prone moving components. The coating thickness needs proper control. Excessively thick grease coating will increase sliding resistance and may accumulate dust and grit; insufficient coating cannot form an integrated damping film, leading to early attenuation of shock‑absorption and silencing performance.
Do not mix this polymer high‑adhesion rail damping grease with ordinary lithium grease, molybdenum‑disulfide‑containing grease or fluorinated lubricants. Incompatible blending will break the polymer‑modified viscoelastic network, reduce surface adhesion and cause severe fluctuation of damping effect. Store in tightly sealed original containers inside cool, dry indoor warehouse. Avoid prolonged high‑temperature storage to retain high‑adhesion damping, shock‑absorption and silencing performance for rail transit guide components.
