A round baler (10) uses double bearing assemblies to journal each end of its bale supporting roll (148) where continuous exposure to the harmful effects of trash, dirt and moisture is at a high level. Each set of double bearings has an outboard bearing (120) that remains exposed to the elements at that location, as well as a second, back-up bearing (118) safely tucked away from the elements in a protected, inboard position. The outboard bearing (120) serves not only as a means for journaling the roll (148), but also as a means for shielding and protecting the inboard bearing (118) against contamination. |
