Ive farmed 45 years. I had one big sweep plow with 10 cylinders. We had very few problems, although it would wear over time. Thr ouside seal is a wiper so of course its job is to clean off the shaft. The biggest problem are bear shafts out in elements during off season. Over time the shaft would pit and cause seal to leak. We would coat them would stuff designed for that purpose.
