Looking for Timken Bearing Kit for Grand Design with Curt 5,100 lb Capacity Axles  

Updated 05/19/2026 | Published 05/17/2026

Question:

Hello, I need to buy bearing seals, or better yet, Timken Bearing kits for a Curt Item V000845621, 5,100 axle on my Grand Design 5th wheel. I have a photo of the label. It also says CURT52-SBSA-86.5-68.5-NOSP-OSL-65517-RED-ABS-7226-BRONZE-30SPT-122446-CAP 5100, manufactured in 8/2024

Hey Don, thanks for the axle info. Based on that the correct Timken bearing kit would be the # TMK72VR that you referenced. Are you looking for a spare set to keep on hand?
