Mounting Paste for Heavy‑Load Metal Joints & Thread Connections

YBS NB 50 is a special high‑temperature assembly and lubricating paste. It is formulated to protect metal mating surfaces against fretting corrosion, scoring and seizure under static load, micro‑oscillation and high‑temperature conditions. It provides reliable separation between metal contact surfaces, prevents galling during assembly, reduces wear and corrosion for bolt threads, press‑fit components, taper sleeves and chuck connections. It can be used for assembly and long‑term protection of heavy‑load mechanical joints.

Operating Precautions

This is an assembly paste, not for rotating rolling bearing lubrication. Do not mix with ordinary lubricating greases or oils; confirm material compatibility with metals and plastics before application. Apply thin layer only; excessive paste may attract dust and impurities. Store in sealed container, keep away from direct sunlight and high‑temperature sources. Not for food‑grade or pharmaceutical contact applications without certification. Dispose of waste paste and packaging in accordance with local environmental regulations.

How To Use

■ Clean gears and remove old lubricant before application.
■ Apply grease evenly to gear teeth and contact surfaces.
■ Use an appropriate amount to ensure full coverage without excess.
■ Apply manually or through a lubrication system.
■ Run equipment at low speed after application to ensure proper distribution.
