Abstract
Rotatable cutting elements for earth-boring tools may include a substrate and a polycrystalline, superabrasive material secured to an end of the substrate. A sleeve may be sized and shaped to circumferentially surround at least a portion of the substrate. Rollers may be sized and shaped for positioning between, and making rolling contact with, the substrate and the sleeve, the rollers configured to rotate relative to the substrate and the sleeve and to enable the substrate to rotate relative to the sleeve. The rollers may be configured to bear at least radial forces acting on the substrate and the sleeve.
