How to Identify Correct Replacement Hub Based on Bearing Part Number or Spindle Dimensions
Question:
Where can I find this? hub with 1 3/8 inch inner bearing and 7/8 inch outer bearing
asked by: Matthew F
Expert Reply:
The bearings in trailer hubs are measured to very precise dimensions, to the nearest thousandth of an inch, such as 1.234-inches. To find a suitable replacement hub to fit on your existing trailer spindles either the bearing part numbers or these precise measurements are needed to ensure you select a hub that fits on the spindles. The new hub must use the same bearings as the original.
If you refer to the linked photo you'll see how these part numbers typically appear on bearings. If these are not available you'll instead need to use a precision caliper to measure the spindle diameter where the inner and outer bearings ride on it. You also need to match the hub to the axle weight rating and choose one with the correct bolt pattern for your wheels.
Once you have the bearing part numbers or measurements you can use the linked page to select a new hub. We have idler hubs and also hub/drums for trailers with brakes.
