High precision: Provides good repeat positioning accuracy, suitable for applications requiring high-precision motion control.
Strong load capacity: Able to withstand large loads, maintain stable motion performance under high loads, suitable for heavy load applications.
Smooth motion: Able to achieve smooth linear motion during operation, reducing vibration and noise.
Application: Widely used in high-precision CNC machine tools, robot joint drives, medical equipment, measuring instruments, electronic equipment, aerospace and other fields.
QIBR - SDA2520V-3 Ball Screw Optimization
Adjustable Dimensions: The screw shaft's terminal end is unprocessed, allowing for additional machining to customize the shape and size according to the customer's ball screw requirements.
Process Optimization: The geometry of the threads and balls is optimized to increase contact area and load capacity.
Further Customization:QIBR can design and optimize ball screws according to customer drawings and operating conditions.
More customization: QIBR can design and optimize the ball screw according to customer requirements for drawings and ball screw working conditions.
QIBR - SDA2520V-3 Ball Screw Quality Control
Dimension measurement: Use a variety of professional high-precision instruments to measure multiple dimensions of the ball screw, with a maximum accuracy of 0.001mm.
Hardness measurement: Use a hardness tester to measure the surface hardness of the guide rail, with a measurement accuracy of ±0.5HRC.
Roughness measurement: Use a surface roughness meter to measure the surface roughness of the ball screw, with a maximum accuracy of ±0.01μm.
Load measurement: A load is applied using a force sensor, and the deformation of the ball screw is measured with a micrometer.
Geometric tolerance: Use a profiler to measure the geometric shape and relative position of the ball screw.
Raw material control: Procurement of steel and parts from ISO 14001 certified suppliers ensures product stability while promoting sustainable development.
Features & benefits
The SDA series features a caged ball design, which helps to reduce friction, minimize heat generation, and improve lubrication retention. This design contributes to a longer service life and higher operational speeds.
The nut is a part that matches the screw, usually made of metal, with a thread structure inside that matches the screw thread. There is also a guide groove inside the nut for accommodating the ball.
