ABSTRACT:
A sealing assembly, kit and method for rotatable shafts. The assembly includes a stationary seal member having an insert receiving opening dimensioned larger than a rotatable shaft, an insert member having an enlargeable shaft-receiving opening adapted to be mounted in the insert-receiving opening in the stationary seal member, and a rotatable seal member adapted to be mounted on the rotatable shaft to engage and cooperate with the insert member. The kit is similarly composed of the same elements but with a plurality of each such element having differing sizes to accommodate rotatable shafts of different dimensions. The method includes providing a stationary seal member, providing and mounting an insert member in an insert-receiving opening in the stationary seal member after which a shaft-receiving opening in the insert member is enlarged to generally conform to a rotatable shaft and the stationary seal member is mounted on a device carrying the shaft, and providing and mounting a rotatable seal member on the shaft. With the sealing assembly, kit and method for rotatable shafts, the invention provides a versatile and effective seal.
