Featuring Hamilton's HPI Swivel Technology
The HPI Technology outperforms conventional CNC-machined ball raceways, kingpinless and unit load bearing swivel constructions.
The new design improves the bearings's element of contact and more than doubles the number of contact points. 
The raceways are also 45% harder than conventional hardened raceways and the surface finish is an incredibly smooth 16 micro inches.
