The HS04, which is manufactured by SKF, is a hydraulic driven, automatic lubricator that has been developed to provide efficient, and reliable quality performance. This high-temperature separating paste is specifically used on hammers, breakers, chisels, bushings, and other parts subject to improper or infrequent use can fail which would delay projects and increase repair expenses. It is a high solid content in the form of copper, and graphite which prevents it from flowing, cold galling, seizing, and premature wear.
