Ball Nut Lead Screw
Ball Screw is made of screw and ball nut. It's function is to turn the rotary motion into linear motion which is a future extension and development of ball screw. The significance of the development is to move into a rolling bearing from sliding action. With little frication, Ball Screw are widely used into various industrial equipment and precision instruments.

Structure and Features
Compact
Because of the internal circulation mechanism using a deflector, the outer diameter is only 70% to 80% of that of the return-pipe nut, and the overall length is 60% to 80%, thus reducing the weight and decreasing the inertia during acceleration.
Since the nut and the support bearing are integrated, a highly accurate and compact design is achieved. In addition, small inertia due to the lightweight ball screw nut ensures high responsiveness.
Capable of Fine Positioning
Being a standard-lead ball screw, it is capable of fine positioning despite the rotation of the ball screw nut.
Accuracy Can Easily Be Achieved
As the outer ring of the support bearing is integrated, the bearing can be assembled with the nut housing on the end face of the outer ring flange. This makes it easy to center the ball screw nut and establish accuracy.
Well-Balanced
Since the deflector is evenly positioned along the circumference, superb balance is ensured while the ball screw nut is rotating.
Stability in the Low-Speed Range
Traditionally, motors tend to have an uneven torque and lower speeds due to the external factors. With this product, the motor can be connected independently with the screw shaft and the ball screw nut, thus allowing micro feeding within the motor’s stable rotation range.
Smooth Motion
It achieves smoother motion than rack-and-pinion-based linear motion.
High Rigidity
The support bearing of this model is larger than that of the screw shaft rotational type. Thus, its axial rigidity is significantly increased.
Compact
Since the ball screw nut and the support bearing are integrated, a highly accurate and compact design is achieved.
Easy Installation
By simply mounting this model to the housing with bolts, a ball screw nut rotating mechanism can be obtained. (For the housing’s inner-diameter tolerance, H7 is recommended.)
The Elements of a Ball Screw
Threaded shaft:
The threaded shaft is the core component of the ball screw. It is made of high-strength steel and has a precise thread profile that the ball bearings move along.
01
Nut:
The nut is the housing for the ball bearings. It is typically made of steel and is designed to minimize friction between the ball bearings and the threaded shaft.
02
Ball bearings:
The ball bearings are what enable the nut to move along the threaded shaft. They are typically made of steel or ceramic and are designed to minimize friction and wear.
03
End supports:
The end supports are used to hold the ball screw in place and support the load. They are typically made of cast iron or steel and are designed to minimize deflection and vibration.
04
Machine tools: Ball screws are used to provide the precise linear motion required in lathes, milling machines, and other CNC machines.
Robotics: Ball screws are used in many robotic applications, including robotic arms and legs.
Aerospace systems:
Ball screws are used in aircraft control systems and other aerospace applications.
Medical equipment:
Ball screws are used in many medical devices, including surgical robots and imaging systems.
Automotive industry:
Ball screws are used in automotive manufacturing, including assembly lines and robotic welding systems.
