Geared Type Rotary Ball Spline
With the Rotary Ball Spline, the shaft has three crests, and along both sides of each crest, two rows of balls (six rows in total) are arranged to hold the crest so that a reasonable preload is applied.
These models are unit types based on model LBR, but have gear teeth on the flange circumferenceand radial and thrust bearings on the spline nut, all compactly integrated.
No Angular Backlash
Optimal for Torque Transmission with Spline Nut Drive
