A seal carrier, which receives a rotatable shaft therethrough, has two spaced apart seals mounted therein. A first annular grease chamber around the shaft is defined between the two seals, and a second annular grease chamber around the shaft is defined between one of the seals and a circular flange of the carrier which is spaced from said one seal. The carrier has a grease inlet fitting in communication with both grease chambers, and has a discharge opening diametrically opposite the inlet fitting. The circular flange is closely spaced to the shaft and defines a small, annular discharge opening therewith. Grease introduced under pressure through the inlet fitting is distributed all around the annular grease chambers, with excess grease being discharged from said discharge openings.
