Question:
I have a 5th wheel which has Dexter 7k axles. Do you carry Timkin wheel bearing that would be compatible? If so, what would the part numbers be?

Expert Reply:
Hey Roger! Assuming your hub uses the standard 7k bearings we have the Timken 14125A # TMK54FR and Timken 25580 # TMK44FR. If you have the original Dexter hubs on there it is safe to assume these are correct.
If you're looking for a full bearing kit you will need to figure out if your grease seal has a 2.125" or 2.25" inner diameter. The # TMK32VR is the 2.125" and the # TMK92VR is the 2.25" kit. If you aren't sure I can use the S/N off your axle tag to identify it just let me know below.
