Bearings for 2021 Boreas XT camper
Updated 06/29/2026 | Published 06/25/2026
Question:
Good day, I have a Cruisemaster CRS suspension on my 2021 Boreas XT camper. The Inner bearing is: NTN 4T-L68149. I cans see the Outer bearing details as the Seal is in the way. I dont want to destroy the seal atm. The Seal is: NAK TC 1.750 2.328 0.250 Do you have replacement bearings/seal for this setup? Thanks.

Hey Paul, the seal dimensions you mentioned are throwing me off as it doesn't seem to match either a 3,500 or a 4,400 lb axle so I can't guarantee what the other bearing number would be. The other thing you can try is pull the hub off and measure the spindle where the bearings ride as that would let me know.

If you plan to add bearing buddies, make sure you get etrailer to supply the special inner seal.

The wheel hub is a Cruisemaster 10×2 1/4", 4 holes. Where I could measure the spindle it's 35 mm. The brake assembly backing plate is: Dexter: 023-086-00. (Surprisingly this is not a Cruisemaster component so perhaps the previous owner have replaced it already) The NAK seal dimensions is in inches and correlates with the Cruisemaster website where it's listed in mm, except for the width,which in my seal is 0.25", and the Cruisemaster website lists the width as 10.16 mm. Their seal is listed as: OD×ID×W= 59.13×44.45×10.16. It's a 3500 lb axle between the 2 wheels. GVWR=3500 lb. Thanks.
