Replacement Hub for Master Pro PT A-4 and National Bearing A-17 Bearings on a Utility Trailer
Question:
I dont have the trailer with me to take measurements: but its a 5 stud bolt pattern, none brake hub style on a single axle 12 foot utility trailer. I have the bearing part #s which U may be able to figure out. Outer smaller bearing which I purchased was a Master Pro PT A-4, Inner larger bearing was a National Bearing A-17. Studs are mounted on the solid flat plate not the X style. I needed to add its a 15 inch wheel, thanks for any help

Based on the information I could find on those 2 bearings it appears that they are the same as L44649/L68149 bearings. Hubs that take these bearings include:
# 84545BX for a 5 on 4-1/2 bolt pattern
# 84545UC1-EZ for an EZ lube axle and 5 on 4-1/2 bolt pattern
# 84550BX for a 5 on 5 bolt pattern
# 845475UC1 for a 5 on 4-3/4 bolt pattern
# 845475UC1-EZ for an EZ lube axle and 5 on 4-3/4 bolt pattern
# 84555UC1 for a 5 on 5-1/2 bolt pattern
The star design is just a newer style of idler hub. They will still fit in place of the older style with the solid metal ring. To determine bolt pattern I have included a link to an FAQ that will help.
