Does spray grease replace grease from a gun?

Not at sealed bearings and points with a grease nipple; those need a grease gun. On open gears, chains, joints, rails and hard-to-reach points, spray grease is the right product.

What temperature range does it work in?

Liquid grease has outstanding thermal stability, and the rubber-reinforced version is formulated for heavy load and harsh weather. For applications at extreme temperatures, work from the product data sheet.

Should the surface be cleaned first?

Yes. New grease over old grease, dust and swarf makes an abrasive paste. Clean the surface with degreaser or parts cleaner first.

Grease & Grease Guns

Grease exists so the lubricant stays where it is put: base oil held in a thickener does not run out of a bearing or a joint. Liquid grease spray combines that cling with the reach of an aerosol — it gets into points a grease gun cannot.

Liquid grease and rubber-reinforced grease

Standard liquid grease (LU-500) gives long-lasting adhesion and effective protection on the surface it is sprayed on. It has outstanding mechanical and thermal stability, and its resistance to water also protects against corrosion and rust.

Rubber-reinforced liquid grease (LU-1000) is for heavy duty: its elastic strength is reinforced with rubber and it keeps assemblies running at loads up to 100,000 psi. It is the choice for resistant metal-to-metal contact and heavy load; the manufacturer's MRO testing measured it staying active on the surface for 25-28 days.
