Question:
Need a bearing seal to replace National Part No. 471750
asked by: Michael W
Expert Reply:
I cross-referenced the National 471750 grease seal for you and found that the seal has a 1.98 inch outer diameter and a 1.25 inch inner diameter and a .25 inch thickness which is comparable to the # 34823 double lip seal we offer.
This being said, from what I found the 471750 is described as a oil or a grease seal while the # 34823 seal we offer is best suited for grease. It's simple to convert to grease in your hub, you'd just need to drain them and pack the bearings. In a boat trailer application I actually prefer grease style hubs as you don't need to worry as much about water entering the hub.
