Thomson Linear Motion Optmized
Ball Splines - Product Overview
Product Details
Ball splines require smaller forces to achieve axial displacement of the outer race while transmitting torque. Thomson ball splines have rolled inner races with non-preloaded outer races. They are best suited for power transmission applications such as motor couplings, translating drive shaft couplings, non-swiveling telescoping struts, and more.
