Ball screws and ball splines

Special support bearings are directly installed on the outer circles of the nuts of the ball screw and ball spline. By rotating or stopping the nut or spline nut, various forms of movement (rotary, linear and spiral) can be performed using only one axis. Its uses include axes of horizontal multi-jointed robots, assembly robots, automatic loaders, machining center devices, and other devices that are most suitable for combinations of rotary motion and linear motion.
[Axial clearance is]< Because the ball spline has an angular contact structure with no dead stroke in the rotation direction, it can perform high-precision positioning. < [Lightweight and compact] The integrated structure enables a design with high precision and small size. In addition, due to the light weight of the nut and the small inertial force, a high degree of responsiveness can be achieved because the nut and the support bearing are in one piece. <【Easy to install】< The ball spline nut is designed to have a structure in which the steel balls will not fall off even if the nut is removed from the shaft, so it is easy to assemble. The ball screw ball spline can be installed simply by bolting it to the support base. (The inner diameter tolerance of the support seat is recommended.) < [Low noise and smooth movement] < Because the ball screw adopts the end cover circulation method, it has low noise and can achieve smooth and smooth movement. < [High Rigidity Support Bearing] < The support bearing on the ball screw side adopts a high rigidity contact angle in the axial direction and the support bearing on the ball spline side adopts a torque direction < high rigidity contact angle, so high rigidity can be obtained of support bearings. < In addition, a special rubber sealing baffle is equipped as standard to prevent the entry of foreign matter < Ball spline and ball screw are used together < Low noise can be maintained even during high-speed operation < Because the R type uses an end cap method, the steel ball is scooped into the inside of the nut The sound is very small. Moreover, the steel balls circulate inside the nut and the noise is very low even at high speed. <
