Spline Shaft Stub

The universal joint is the core component of the Cardan Shaft, which allows the
shaft to transmit rotational motion when the angle is inconsistent. The
universal joint can absorb angle changes and maintain the continuity of power
transmission.
Drive Shaft Tube
The drive shaft tube is the main shaft body part connecting the universal
joint, which is responsible for transmitting rotational motion from the engine
or power source to the drive device or other mechanical parts. The length and
diameter of the shaft tube are adjusted according to the specific application.
Sliding Spline
The sliding spline allows the Cardan Shaft to expand and contract in the axial
direction (length direction) to adapt to the length changes that occur in the
transmission system, such as the movement of the suspension system or load
changes. This part realizes the free expansion and contraction of the shaft
through the mutual engagement of the internal and external splines.
