What bearings did you use around the CIMs? Are they roller bearings or ball bearings? Also, do you have a sleeve around the CIM, or are the bearings riding on the CIM?

Between the steering gear and the mounting plate there are two .25" diameter semi circle grooves (one in each plate) with .25" diameter delrin balls running in them, essentially forming a "deep groove" thrust bearing that can also handle axial load. (This was borrowed from team 16 who has perfected this bearing and graciously answered all of my questions regarding it)

The bearing is then kept from coming apart by a set of white delrin sliders that go up over the mounting plate from the steering gear and retain it.

Around the CIM exists a ~.090" thick 4340 alloy steel sleeve (we went pretty hard as it was round 1 of this bearing concept). Riding on the sleeve are 12 r3 ball bearings (6 on each side) each riding on a 10-32 bolt.
The bearings also have a groove in the steel sleeve that is deeper than the outer race of the bearing providing an thrust surface to retain the wheel in the middle of the module.
