Trailer Bearings: The Essential Guide to Keeping Your Trailer Rolling
Trailer bearings are critical components that keep your trailer moving smoothly and safely. They reduce friction between the axle and the wheel, allowing the wheels to rotate freely. Without properly maintained bearings, your trailer can experience premature wear, decreased fuel efficiency, and even catastrophic failure.
Industry Insights:
According to the American Trucking Association, over 42% of all trailer failures are caused by bearing issues. Regular inspection and maintenance of your trailer bearings can significantly reduce the risk of these failures and keep your fleet running at peak efficiency.
