Abstract

The bearing is intended for an electric motor and has a bearing bush(2) in sintered metal with a lubricant reservoir formed by a felt ring (5). the ring has openings(6) and there is a locating disc(3) with corresponding openings(7) or recesses whilst the bearing housing(4) contains radially extending grooves (10, 11). The openings(6) may be spaced at a maximum distance of twice their diameter. They may be arranged near the circumference of the ring or near the bush.
