A camera lens suspension assembly in comprises a support member including a support metal base layer formed as single piece of metal, a moving member including a moving metal base layer formed as a single piece of metal, a plurality of bearings and smart memory alloy wires. The support member includes a bearing plate portion, a plurality of static wire attach structures, and a plurality of mount regions, all formed from or on the support metal base layer. A printed circuit on the support metal base layer includes traces extending to each static wire attach structure. The moving member includes a moving plate portion, a plurality of elongated flexure arms extending from a periphery of the moving plate portion and including mount regions on ends opposite the moving plate portion, and a plurality of moving wire attach structures, all in the moving metal base layer. The bearings are between and engage the bearing plate portion of the support member and the moving plate portion of the moving member, to enable movement of the moving member with respect to the support member. Each of the smart memory alloy wires is attached to and extends one of the static wire attach structures and one of the moving wire attach structures.
