Abstract
An archery bow is provided including an axle assembly that compresses bearing and other components between limb portions to clamp those components against one another, with zero gaps therebetween, yet enable a cam to freely rotate relative to the axle. The bow can include bearings having an inner portion, and an outer portion non-rotatably joined with a cam. A fastener is operable in a compression mode to exert a compression force, such as an axial clamping force, against the bearing inner portion so it is non-rotatable relative to the axle, while the outer portion remains uncompressed and rotatable relative to the axle. The assembly can include a compression spacer clamped under the compression force between inner portions of bearings. These constructions can enhance the consistency of cam rotation and promote a smooth draw of the bow. Related methods are also provided.
