    Ball Screw/Splines and Bearings

    Image of Product. Front orientation. Contains Annotated. Ball Screw/Splines and Bearings.
    From one compact system, transmit linear or rotary motion or both at once (sometimes called spiral motion). Because of these different motions, these ball screw/splines and bearings create efficient, fluid movements in complex automated applications, such as pick-and-place robots.
    The ball bearings move smoothly and precisely, even at high speeds. They're powered independently, so you can drive one bearing at a time or both together to coordinate movements.
    The ball screw/splines are hardened on the surface, so they stand up to repeated motion. They’re also hollow, so you can run electrical wiring, compressed air tubing, coolants, or lubricant through their center.

    Mounted Linear Bearings for Ball Splines

    A flange with mounting holes makes it easy to attach a load to these bearings. Create a compact linear and rotary motion system for robots and other applications requiring complex, fast movements, by combining them with ball splines. These bearings move smoothly and precisely even at high speeds along ball splines while grooves on the ball spline transmit rotary power. Clip a retaining ring (not included) into the groove on these bearings to position them in your system.

    Splines are alloy steel for high strength and wear resistance. They're hardened only on the outside, so they stand up to repeated motion while keeping their center soft enough to absorb stress from shifting loads.
    Step-Down End—Splines with a step-down end have a shoulder near the end to stop gears, sprockets, and bearings.
