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.

Eject parts smoothly from your mold without liquid lubricant—these bushings reduce friction between ejector pins and plates. These bushings have graphite plugs to help the pins slide without wearing your assembly.

Graphite plugs in these bushings help pins, punches, and other components slide through molds and dies without the mess of grease or oil. These bushings keep the upper and lower halves of your setup aligned. Made from aluminum-bronze, they can handle the high loads and repeat motion of production lines.

Convert the rotary motion of a smooth shaft into linear movement. Often used with conveyors and other equipment that already have a rotating shaft, these drive nuts move loads such as carriages and scanning sensors or cameras in a straight line. Internal friction rollers contact the shaft at an angle to create motion. The bearings are lubricated for life, so the drive nuts require little maintenance. Thrust adjustment bolts let you fine-tune the amount of force the drive nuts exert. If the load becomes too heavy or something blocks the motion, the drive nuts will slip along the shaft instead of damaging your equipment. You can push a load with these drive nuts or mount them to the top of a load to carry it.
