The use of open porous foam polyurethane sprockets to automatically apply the gear and rack lubricant is a very economical technical solution.
The expanded polyurethane (PU) does not transfer forces or twists but only releases lubricant in the contact area between the gears.
The material retains the lubricant and distributes it in small quantities in the contact area of the teeth. The excess lubricant is reabsorbed, which prevents grease spills from over dosing.
The FlexxPump can be customized to match customer requirements.
