The SKF SYSTEM 24 LAGD consists of a transparent container filled with a specified lubricant and a cartridge containing an electrochemical gas cell. Once activated the internal batteries are electrically connected and gas production can begin building up the pressure until the piston moves, pushing the lubricant into the application. The gas production rate is proportional to the electrical current. Therefore, each position of the dial is designed to allow a given current flow, thus adjusting the dispensing period between 1 and 12 months.
