What is the Inner Diameter of Trailer Bearing # 25580 and Trailer Bearing # 14125A


I need to know the diameter of both of the bearings on the inside to see if it will fit my axel. this fits an old shop made trailer. I have an 8 hole hub now but no brake drum.

I went out to the warehouse and pulled bearing # 25580, and # 14125A, to measure them. Bearing # 25580 has an inner diameter of 1.74 inches. Bearing # 14125A has an inner diameter of 1.225 inches. I used digital dial calipers to take the measurements.
