The only hub we have that is currently available for a 3/4 inch spindle is Item # AH15450ECOMP. This is an agricultural hub that fits 3,000 lbs axles for 4 on 5 inch bolt pattern. It takes an inner bearing, Item # LM67048, and outer bearing, Item # LM11949. It is meant to be used for low speed (less than 20 mph) agricultural applications. It is designed for a spindle like Item # TRU54FR.

If you can find the actual bearing number on your old bearings and seal or can send me a bearing measurement then I could find the correct parts for you. To find the correct bearings measurement, you will want to use a digital caliper like Item # PTW80157 to measure both inner and outer bearings. This will tell us what we need to get the correct replacement parts for you (additional information on measuring bearings attached).

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…
