Features and advantages of QIBR ball screw SDA series

QIBR ball screw SDA series solve multiple key problems across various fields, mainly in the following aspects:

1. High-speed feed and micro-feed capability

Due to the rolling motion of the balls, the starting torque is extremely low, eliminating creeping issues, making it ideal for high-speed and micro-feed applications.

2. Low friction and long service life

Unlike traditional sliding friction mechanisms, the Ball Screw SDA Series transmits power through rolling friction, reducing energy loss and wear. Since rolling friction generates less heat compared to sliding friction, the system experiences lower temperature rise, enhancing durability and stability.

3. High precision

The Ball Screw SDA Series enables high-precision motion control, making it widely used in applications requiring precise positioning, such as CNC machine tools and precision instruments.

4. High load capacity

The rolling motion of the balls allows for better load distribution between the screw shaft and the nut, significantly enhancing the load-bearing capacity compared to traditional linear bearings. This makes it well-suited for mechanical transmission applications that require higher load capacity.

Performance enhancements and solutions for QIBR ball screw SDA series

1. Precision improvement

Using high-precision machining equipment (such as CNC machines and grinding machines) ensures that the screw and ball tracks achieve superior geometric accuracy, dimensional precision, and surface finish.

2. Reduced friction and increased transmission efficiency

High-performance lubricants (oils or greases) can reduce friction, improve transmission efficiency, lower temperature rise, and extend service life.

Optimized lubrication design: By designing the contact angle and contact method between the balls and the track and employing an effective lubrication system, friction can be reduced while maintaining efficiency.

3. Improved torsional strength and stability

Enhancing the size ratio of the screw or using high-strength materials can increase its resistance to bending and torsion, thereby improving overall stability.

4. Self-locking design

The self-locking design of the ball screw allows it to hold its position without load or with minimal load, reducing unwanted movement when the system is stopped and improving stability.

Main application fields of QIBR ball screw SDA series

1. CNC machine tools

Ball screws are widely used in CNC machine feed systems, providing high-precision positioning and motion control.
