In many grease lubricated bearings, periodic regreasing is required. The regreasing interval and quantity are a complex function of speed, operating temperature, shaft diameter etc. Over greasing can result in overheating, causing damage to seals, also sometimes resulting in grease to liquify prematurely Under greasing is a sure recipe for equipment failure.

The simple solution is to install a LUBEX spring loaded grease feeder. This grease feeder has to be installed directly over the bearing housing in place of grease nipple. (Ref. fig.2)

The grease feeder can be installed in any position i.e. straight, 45°, 90° or upside down by using a suitable adaptor. (Ref. fig. 3.)

How does LUBEX grease feeder work?

Fill grease in the grease feeder by a grease gun through a non return valve (MW) in grease feeder. Grease pushes up the piston against a spring causing the spring to compress. A clear polycarbonate dome allows easy visibility of grease within the dome, also indicates when it is time to re-fill the grease feeder. Since there is no way your can see what is going on inside a bearing, bushing, pillow block, there is only guesswork, LUBEX dispenses right amount at right place all the time. Grease is discharged from LUBEX grease feeder base to the bearing at minimum pressure usually less then 2 psi.

The bearing’s natural venturi (vacuum) causes the grease to gradually flow into the bearing. This causes the bearing to use grease only as and when required. Grease is not forced or packed into the bearing. When the bearing or equipment stops the grease flow stops.
