Abstract
A sealing device for sealing off an opening between a shaft and a grease-lubricated split bearing housing comprises two halves divided by a diametrical cut and each having a main body arranged in a circumferential groove in the bearing housing opening. The sealing device is provided with sealing lips spaced apart from each other and forming an intermediate grease reservoir, and reinforcing portions arranged between the main seal body and the sealing lips to facilitate sealing engagement between the sealing lips and a shaft when an upper bearing housing half arranged with the upper seal half is mounted onto the shaft while the shaft is resting in a lower bearing housing half arranged with the lower seal half.
