ABSTRACT:
A large round baler includes a plurality of bale-forming rolls which each have opposite ends defined by stub shafts rotatably supported in respective bearings fixed to opposite side walls of the bale chamber. The rolls are each in the form of a hollow cylindrical drum and each stub shaft includes a flange having a diameter corresponding to the inside diameter of the drum and being secured to the drum at a location spaced inwardly from an end face of the drum. For preventing crop particles and juices from reaching each bearing, a ring-like seal body is fixed to the outer surface of the flange in concentric relationship to the stub shaft and to, and between, a cylindrical sealing surface of a collar that is fixed to the wall and a ring that is also fixed to the wall. The seal body has a plurality of radially outward projecting lips disposed very close to the sealing surface of the collar and a single radially inward projecting lip disposed very close to the ring.
