Description
REVHD RM-T03 RevMax trailer axle wheel seal for TN-style tapered spindles, replacing National 370025A / 380025A and SKF 46300. HNBR sealing lips run wider OD and ID than a standard CR/SKF seal for greater contact patch and longer service life on oil-bath and grease hubs. Fits Hendrickson, Meritor, and Dana/Spicer trailer axles using the TN tapered spindle design.
Signs You Need a New Wheel Seal
- Oil or grease leaking from the hub onto the wheel, brake drum, or backing plate
- Contamination, water, or metallic debris visible in the hub oil
- Wheel-bearing rumble, growl, or unusual heat at the hub
- Visible cracking, hardening, or wear ridge on the existing seal lip
- Hubcap window showing low oil level after a recent service

Applications
This wheel seal fits trailer axles built around the TN tapered spindle, including:
- Hendrickson trailer axles (TN spindle)
- Meritor trailer axles (TN spindle)
- Dana / Spicer trailer axles (TN spindle)
- Great Dane, Wabash, Utility, Vanguard, Hyundai Translead, Stoughton trailers, and other van / flatbed / reefer / tank / RGN trailers running TN tapered axles
Verify your spindle type, hub bore, and existing seal OD before ordering. The 6.000 in. OD x 4.625 in. ID dimensions identify the TN spindle envelope; non-TN axles (e.g., R-spindle) require a different seal.
