Can a Different Grease Seal Be Used on Dexter Trailer Hub and Drum # 8-247-50UC3

Question:

Can 168255TB seal be used with the Code: 8-247-50UC3 drum assembly? The manufacturer specifies the 168255TB seal which has different slightly different specs than the 58846 grease seal. Thank you

The Dexter Trailer Hub and Drum Assembly # 8-247-50UC3 that you referenced calls for a single-lip grease seal # 58846 which has an inner diameter of 1.719 inches and an outer diameter of 2.565 inches.

The seal you referenced, part # 168255TB, is a double-lip type with an inner diameter of 1.687 inches and an outer diameter of 2.561 inches. We do not recommend using other than the specified seals for any hub application. Using an incorrect size will either allow grease to leak out or result in a too-tight fit that will lead to premature wear of the seal's inner surface.

We do offer the correct seal # 58846; and the linked video on bearings and seals may be helpful to you.
