carrier spacer dimensions running £4.50 bearings
When the two bearings are fitted in a carrier wheel upto the locating shoulder, the distance between them is 1 5/8" which is 41.275 mm, so your spacer needs to be 41.275mm long on its central widest part., the widest part is 60mm, with 50mm diameter for the bearings to go on either end and a 40mm hole drilled through the middle.
if you add 2 x 27mm then add 41.275 you get 95.275 mm for the total length of the spacer, I think my machinest made the total length as 95 mm, so each 50 mm diameter part was about 26.9 mm long, he did this so when you tighten up the nut you nip up the bearing onto the spacer. I hope you can understad this without a drawing, remember each wheel casting is different. I am running two of these spaced wheels on my carrier and they run fine with no wobble or movement, I have even left the bearing grease covers in the bearings. Best to have one made up, fit it and put it on your carrier and tighten it up, then check the tolerences. so just to recap, total length = 95mm, 40mm hole through the centre, each spigot the bearing sits on is 50mm diameter and 26.9mm long, central part of spacer is 41.275mm between shoulders. I know 0.075 mm is lost someware but dont worry.
