Cheap Price Ball Spline For CNC Lathe

Product Application

The ball spline is a type of rolling guide spline. This is an innovative product. Through the rolling of the balls in the groove connected to the shaft, a larger allowable load can be achieved than when a linear bushing is used, and it can transmit torque while performing Linear Motion.

The ball spline is composed of a spline shaft with a transfer groove and an outer cylinder. A retainer, side ring, steel ball, etc. are installed inside the spline outer cylinder, and it is designed and manufactured for smooth sliding.
Large load capacity and long life
Because the track surface is ground into an R shape close to the diameter of the steel ball, the contact area of the steel ball is increased, the load capacity is increased, and the life is prolonged.
Make additional processing easier
The NB ball spline adopts a shape in which a transfer groove is provided on the round shaft, so it is easier to process the shaft end during installation.
Rich type
The diameter of the NB spline shaft is 4~100, and the outer cylinder shape is divided into cylindrical, flange, and slider type. Stainless steel type can also be produced according to different models, and the appropriate type can be selected according to the application.
High-speed movement and high-speed rotation can be realized.
The outer cylinder is small and compact, with good balance, and can give full play to its performance even in high-speed operation or high-speed rotation.
Realize high-precision torque transmission
The transfer groove of the shaft and the outer cylinder forms an appropriate contact angle with the steel ball, which can transmit a large torque. In addition, by applying preload, the gap in the rotation direction is eliminated, thereby improving rigidity and realizing correct rotation positioning.
It is optimal for machines using a combination of rotary and straight motions, such as scholar robot's Z-axis, assembly robot, automatic loader, and machining center's ATC equipment.
