Place a recirculating-ball bushing on a shaft and what do you get? Frictionless movement of the shaft. But, create grooves along the axial length of the shaft that correspond to the radius of the ...

Ball splines provide nearly friction-free linear motion while simultaneously transmitting torsional loads. The path of the bearing balls is straight, not helical, which allows for a very efficient ...

The ball spline, now 55 years old, is a motion component that has stood the test of time but has not stood still. Indeed, in recent years, this innovation has evolved with sizes and designs that allow ...

Ball splines are often lumped into the category of recirculating linear bearing guides (aka linear bushings), but they offer functionality beyond that of traditional linear bushings. Standard ball ...
