    Mounted Linear Bearings for Ball Splines

    Image of ProductInUse. Front orientation. Contains Annotated. Ball Splines and Bearings. 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.

    Sleeve Splines and Bearings

    Image of ProductInUse. Front orientation. Sleeve Splines and Bearings.
    Often used in wet and dirty environments, these sleeve splines and bearings create a compact linear and rotary motion system. The grooves on the splines transmit rotary power as the sleeve bearing moves freely along their length. Sleeve bearings don't have moving parts that can be damaged from dirt and debris. And they don't need to be lubricated, making them overall lower maintenance than ball bearings.
    Splines
    Image of Product. Front orientation. Sleeve Splines and Bearings. Splines.
    Splines are PTFE coated to reduce friction, so bearings slide smoothly and last longer. They’re stainless steel, so they won’t rust.
