That CIM sleeve is a beefcake. See linked cartoon-CAD of our 2016 winch. (We ended up using an igus bearing, not the PTFE called out in the cartoon. Metric 64mm i.d. fits nicely over the CIM sleeve paint. See picture of the innards also.)
My theory as a motor designer: if you have more than the minimum steel required for magnetic flux, the excess should perform another useful function to justify its weight, cost, claimed space, etc.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
