Best Single Ball Bearing

Witproton Ball Splines - Both Ends Tapped 8mmX270mm 1pc

Low friction: The ball does not cycle and can achieve rolling motion with minimal friction..
High precision linear movement: as part of shaft and nut, the clearance in rotation direction can be adjusted to ensure accuracy..
Transferable rotating torque: the ball rolls on the ball groove of the spline shaft and moves in a straight line while transferring the rotating torque..
Compact design: even a single shaft mechanism can move in a straight line, while keeping the nut in the direction of rotation without deviation..
Large bearing capacity and long service life: Because the rolling surface adopts r-shaped ball groove matching with the ball diameter, the contact area is large, the bearing capacity is strong and the service life is long..
