The LS Bell Hammer series is based on class 4 petroleum, which is most suitable for rubber and resin among industrial fats and oils.
If you have problems with fats and oils using our products, the same results will be obtained with other fats and oils.
The main cause of swelling and deterioration of seal parts is cleaning with a parts cleaner before applying oils and fats. The point that is easily mistaken here is that swelling and deterioration do not appear immediately. When swelling or deterioration appears with a delay, the fat is already applied, so it feels as if the fat is the cause.
There are many people who misunderstand these actions and changes and send out incorrect information. This is a very disappointing situation as it can be seen well in chemical products other than our company.
