It has the same contact structure as the LBS shape, with gear machining on the outer flange and a unit type where bearings are assembled on the outer diameter.
The type with support bearings, the rotary ball spline LTR, features gear machining on the flange outer circumference of the LBR type, and is a unit type where radial and thrust bearings are compactly combined in the spline nut section. The ball rows are held in a way that allows them to circulate in a lined motion due to a special synthetic resin retainer, so the balls do not fall out even when the spline shaft is removed. 【Angular Backlash "Zero"】 The structure allows the ball rows to sandwich three rows of rolling protrusions evenly distributed around the outer circumference of the spline shaft, enabling preloading and eliminating backlash in the rotation direction, thereby increasing rigidity. 【Compact Design】 The structure combines radial and thrust bearings compactly in the spline nut section, allowing for a compact design. 【Easy Installation】 It can be easily installed by simply securing it to the housing with bolts. 【High Rigidity】 By providing a large contact angle and appropriate preloading, high torque rigidity and moment rigidity can be achieved. Additionally, the needle bearings in the support section enable strong and rigid nut support against radial loads.
