YBS-46 MR 401 White High‑Pressure Assembly Lubricating Paste,‑40℃~150℃ Anti‑Fretting‑Corrosion Paste for Press‑Fit Joints, Spline Shafts, Plastics & Elastomers

YBS-46 MR 401 is a clean‑looking high‑performance mounting paste developed for precision heavy‑duty assembly and long‑term thin‑film lubrication. Formulated with synthetic base oil, lithium‑soap thickener and selected solid lubricants, free of lead, cadmium, nickel, sulfur and halogens. It offers excellent load‑carrying performance, suppresses tribo‑corrosion (fretting corrosion) and stick‑slip effect caused by vibration, micro‑oscillation and boundary friction. It shows good material compatibility with copper, aluminium and other non‑ferrous metals, as well as many plastics and rubber elastomers. Its white‑ivory paste leaves no dark stains on precision surfaces. Widely used for press‑fit pins, bolt connections, flanges, spline shafts, ball‑and‑socket joints, low‑speed bearings and shaft seals. It protects components during assembly and long‑time service, simplifies disassembly and lowers premature wear and maintenance cost。
