Scanning for Ideas: Single-Point High-Volume Lubricators

The Lage 125 and 250 lubricators from SKF, Kulpsville, Pa. (skf.com), have double the capacity of most other single-point lubricators.

They hold up to 250 ml of oil or grease, bridging the gap between low-capacity lubricators and multipoint systems. The electromechanically driven devices can lubricate roller bearings, open gears, chains, and other components. They have a 4.5-V battery pack, motor, and a canister filled with grease or oil. The motor turns a threaded spindle that drives a piston. The piston, in turn, pressurizes the canister to 5 bar. Both units can also send lubricant along feed lines so that the drive components aren’t exposed to high temperatures or vibrations. Maximum feed line length is 10 ft for grease, 16 ft for oil.
