ABSTRACT:
A wick feed oil lubrication system for a bearing has a special wick element that is self-supporting and wear compensating. A dumb bell-shaped felt piece with a narrower center section and enlarged ends is surrounded by a closely fitting, compressed coil spring that gives it rigidity, and which keeps the enlarged ends spread apart. When installed, the wick element and supporting spring are compressed between the bearing spindle and bottom wall of the oil reservoir, running through a loosely fitting passage in the surrounding hub. Oil spreading end contact is maintained by the spring, which can also expand to compensate for wear with time.
