About the 60 series
Same bore as the 62, but thinner. A smaller OD and narrower. Used where there's no room: gearbox layshafts, small rollers, fans, power tools.
Lighter load than a 62. Don't swap a 60 into a 62's place with a sleeve to make it fit; it'll fail long before the 62 would.
Same bore, different size
