TY - JOUR AB - FOR many years the concept of maintaining relatively low operating pressures for centralized grease lubrication systems has been virtually universal in this country, due mainly to a general apprehension of the term “high pressure”. This same apprehension of higher pressure systems was prevalent in hydraulic power systems until very recently. However, with the advent of the present‐day sophisticated high pressure hydraulic systems demanded primarily by the aviation industry, modern concepts of hydraulic systems throughout industry in general have resulted in operating pressures generally within the range of 200 to 300 bar.
