Danaher Motion 5708945 Ball Spline Outer Race Only 1.500 In Spline Nominal

Description:

The Danaher Motion 5708945 Ball Spline Outer Race is used in precision linear motion systems to provide smooth linear travel while simultaneously transmitting high torsional loads. Commonly installed in CNC machine tools, industrial robotics, automated assembly systems, packaging equipment, semiconductor machinery, and material handling systems utilizing a 1.500-inch nominal ball spline shaft. Maintenance teams, OEM machine builders, and system integrators use this outer race for machine repairs, linear motion retrofits, automation upgrades, and replacement of worn ball spline bearing assemblies.

Applications:

The Danaher Motion 5708945 is designed for high-precision linear motion applications requiring simultaneous rotational torque transmission and smooth axial movement. It is widely used in CNC machining centers, robotic actuators, automated manufacturing equipment, indexing systems, pick-and-place machines, packaging equipment, and custom OEM machinery where accurate positioning, high load capacity, and low-friction linear travel are essential.
