The NB BALL SPLINE is a linear motion mechanism utilizing the recirculating motion of ball elements that can sustain loads and transfer torque either simultaneously or independently. It can be used in a wide variety of applications including robotics and transport type equipment.
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
Configurations and Applications
To support a wider range of installations and applications, NB manufactures several different ball spline nuts:
SSP/SSPS cylindrical-type spline nuts with a key groove and special key
SSPM cylindrical-type spline nuts without a key groove, with lock plates
SSP-AM/SSPS-AM special compact cylindrical-type spline nuts with a countersink and special key
SSPF/SSPFS flanged spline nuts
SSPT flanged spline nuts with two side cut flange
We also can machine spline shafts to custom specifications. All NB ball spine nuts bearings feature standard side seals for dust protection. For detailed information about each product, download the NB ball spline catalog or speak with a sales representative directly.
