Hiwin
Hiwin ballsplines are linear motion systems, which can be used in SCARA robots, pick and place applications, and more. Offering flexibility for the design engineer, ballsplines do not require a horizontal base like linear guideways. An upgrade from bushings, Hiwin ballsplines and nuts are made of the same high-quality materials as Hiwin’s ground ballscrews and ballnuts.
Features include:
- Transmission of torque – the steel balls traveling on the groove with angular contact offer relative movement between the nut and the screw to achieve torque transmission.
- Integral structure – the integration of the nut and support bearings allows the ballspline to achieve high precision and a compact design.
- Easy installation – with the optimized retainer design, the nut can easily be removed from the spline shaft and the steel balls will remain secure in the nut.
- Lubricant path – the optimized lubricant path allows grease to be directly guided to the ball track improving lubrication and increasing service life.
IKO
IKO designs and manufactures a variety of compact ball spline guides to achieve precise linear motion across a diverse range of applications, from medical equipment to semiconductor manufacturing. External cylinders enable smooth linear motion along a spline shaft. IKO ball splines also provide maintenance-free options from the C-Lube line with a built-in lubrication unit.
Nippon Bearing
Nippon Bearing ball spline is a linear motion mechanism utilizing the recirculating motion of ball elements. It can be used in a wide variety of applications including robotics and transport type equipment. The NB Rotary Ball Spline can be used for both rotational and linear motion, including: SCARA robots, the vertical shaft of assembly equipment, and tool changers and loaders.The NB Ball Screw Spline combines ball screw and ball spline on a single shaft, allowing linear actuation, torque transfer, and rotational motion with a single compact assembly. It can be used in SCARA robots, the vertical shaft of assembly equipment, and tool changers and loaders.
