Ball Spline SSP-SSPM

NB ball splines are used in a wide range of applications, including robotics, transport-type equipment and other machinery where it is necessary to sustain heavy loads while transferring torque smoothly. Several models are available, including various nut and shaft configurations.

Key Features At-a-Glance

NB ball splines are comprised of a shaft and nut assembly. Ball spline shafts feature raceway grooves. Nut assemblies consist of an outer cylinder, retainer, side rings and ball elements. This type of configuration offers many advantages, including:

• Reliably smooth motion with specially designed spline nut and shaft
• High load capacity and long travel life are realized by large ball contact areas and machined grooves that maintain a close radius between shaft and nut components
• Precise high torque transmission capability with an effective contact angle between shaft and ball elements
• Adjustable preloads that can be configured to deliver higher rigidity and positioning accuracy
• High-speed motion performance is realized with a well-balanced, compact outer cylinder design
