GBLY series rotary spline
Nut rotating ball screw is a special bearing sleeve installed on the outer diameter of the nut to make it operate. By rotating or stopping the nut, only one shaft can operate in two modes (rotation and spiral). The rotary ball spline is equipped with a special bearing sleeve on the outer diameter of the spline outer cylinder to make it operate. By rotating or stopping the nut, only one shaft can operate in two modes (rotation and linear). Rotation is achieved through ball screw splines, which allow the nut/outer cylinder to rotate or stop, allowing for three modes of movement (rotation, spiral, and linear) with just one shaft. Suitable for horizontal multi joint robotic arms (SCARA), industrial robots, automatic loaders, laser processing machines, conveyors, ATC devices in machining centers, etc., it is most suitable for use in combination devices of rotational and linear motion.

Zero clearance in rotation direction/high positioning accuracy
The contact angle between the nut and the steel ball is 40 °, and the bearing DB type (back-to-back combination) design is adopted. Due to the wide span between the effective centers of the ball groove, this design is particularly suitable for bearing moment loads. (See Figure 1.1.1)

High speed/smooth operation
The rotating series screws are all designed with high lead, allowing for high-speed, smooth and smooth movement.

Low noise
Through high-precision grinding technology, the steel ball smoothly travels along the tangent direction inside the nut, reducing the noise and friction caused by yang stagnation.

Easy installation/space saving
The nut and bearing sleeve are integrally formed, and the nut has a small volume and a large assembly space. When assembling, simply lock the screws and bearing sleeves onto the support seat, which is very convenient.

Precision specifications
Please refer to tables D05-09 for detailed information.

Selection of shafts (solid shaft, hollow shaft)

When the diameter of the spline shaft end or middle part is large, GAOJ-K will perform cutting processing according to customer needs. For areas that require piping, wiring, exhaust, or weight reduction, hollow spline shafts can be used in combination.
