GC651 Improved Automatic Grease Cup

The improved automatic grease cup is of extra heavy substantial construction. It is particularly well adapted for use on movable bearings or where there is excessive vibrations. The body of this cup unscrews from the bottom for filling which is regarded by some engineers as a more convenient arrangement.
