What are Oil Bath Trailer Hubs?

Oil bath trailer hubs are designed to provide better lubrication and protection for the wheel bearings compared to traditional grease-packed hubs. They use oil to keep the bearings lubricated, which helps reduce friction and heat. I found that this design can lead to longer bearing life and less maintenance over time.

Factors to Consider When Buying

When I was in the market for oil bath trailer hubs, there were several key factors that I considered:

1. Size Compatibility: I made sure to check the size of my trailer’s axles and wheels to ensure the hubs would fit properly. It’s crucial to get the right dimensions for optimal performance.
