These lubricators can be set to expel grease over variable amounts of time to suit the application and bearing size. They can also significantly reduce the amount of labor required to individually grease the bearings as well as help to alleviate the ingress of contaminants by applying constant pressure on the bearing.

To understand why so many rulesofthumb exist, it may help to review some basic design factors for sleeve bearing machines, starting with the relationship between power, torque and speed. Torque (lbft) = hp x 5252 / rpm or Torque (N·m) = kW x 9550 / rpm. It follows that the higher the torque (lower speed and/or higher hp/kW rating), the ...
