HOW TO SELECT THE RIGHT MODEL
Pick a genuine Bearing Buddy® to match your hub bore. To convert a model number to the hub bore in inches (or dust cap diameter), simply place a decimal point after the first digit in the model number.
Model #1980, for example, fits a 1.980'' bore hole diameter. Our 2080T (threaded model 2080) will fit the Reliable oil bath unit that is on many of the EZ Loader trailers.
A somewhat less accurate, alternative sizing method, uses our Size Gauge Card. ( Click here ) The card can be used to select a Bearing Buddy® model based on the size of your dust cap. *The 1980 and 1980A both fit a hub bore of 1.980 inches, however the 1980A has a blue ring which acts as a visual lubricant level indicator inside the hub.
