When you use an electric or pneumatic grease pump in a very noisy area (you cannot heard the sound of the pump), how do you know if the grease goes into the bearing? how do you calculate the amount of grease you put? Do you use a special adaptor? I heard about an electronic counter but it is very expensive and fragile, what else??
Thank you for your help.

Good Day,

The LubeChecker is a tool designed to let you know when the grease is in the bearing. It adapts to your grease gun and monitors the shock pulses from the bearing and indicates the effect of the fresh lubricant on the oil film inside the bearing. Instead of assuming your bearings are correctly lubricated, you can immediately watch the result.
