Grease is composed of a thickener (sponge) and a base oil (oil and fat) contained in it.
When friction occurs, the base oil (oil and fat) exudes from the thickener (sponge) and exerts a lubricating effect.
Due to the characteristics of the base oil (oil and fat), LS bell hammer grease has the property that the base oil (oil and fat) is more likely to seep out (oil leakage/drip) than ordinary grease.
