Support Units(Shape:Round, 2 Set Screw Flats at both ends)

Support units are special parts for bearings used in a set together with a ball screw. Support units come in various shapes, such as square, round and round 2-surface chamfered. There are also 2 different types—models used at the fixed side and models used at the support side. Support units attach to the fixed side and support side of a screw shaft, enabling the screw shaft to be mounted in the correct position. A bearing integrated into the body of the support unit enables stable shaft rotation. Support units are available with various types of bearings, sizes, shapes and surface treatments. Models for various applications, operating environments and mounting spaces can be selected. Support units can be mounted in equipment as-is, with no need for additional processes or machining.

                              FAQ Ball Screw Support Units

                              Question: What are Ball Screw Support Units?
                              Answer: Ball screw support units are essential components used to support and stabilize ball screws in linear motion systems. They play a crucial role in ensuring smooth, precise, and reliable operation of the system.
                              Question: Why are Ball Screw Support Units Important?
                              Answer: • Precision and Accuracy: Support units help maintain the accuracy and precision of the linear motion system by preventing deflection and vibration of the ball screw.
                              • Extended Lifespan: Proper support reduces friction and wear on the ball screw, leading to a longer lifespan.
                              • Reduced Noise and Vibration: Effective support units minimize noise and vibration, improving overall system performance and user experience.
                              Question: What are the Different Types of Ball Screw Support Units?
                              Answer: • Pillow Block Bearings: These are simple and economical support units that provide basic support to the ball screw.
                              • Flanged Bearings: These units are attached to a mounting surface using bolts and are suitable for various applications.
                              • Compact Support Units: These are compact and lightweight units that offer high rigidity and precision.
                              • Adjustable Support Units: These units allow for fine-tuning of the ball screw alignment and can accommodate variations in installation.
                              Question: What Are the Common Applications of Ball Screw Support Units?
                              Answer: Ball Screw Support Units are widely used in applications requiring precise linear motion, including
                              • CNC Machines: Used to support the ball screws in the X, Y, and Z axes.
                              • Industrial Robots: Provide support for the robotic arm's linear motion.
                              • 3D Printers: Essential for precise positioning of the print head.
                              • Medical Equipment: Used in various medical devices requiring precise linear motion.
                              • Semiconductor Manufacturing Equipment: Support high-precision motion systems.
                              • Packaging Machinery: Ensure accurate and reliable packaging processes.
                              Their design helps maintain accuracy and stability in high-load, high-speed environments.
                              Question: How Does Thermal Expansion Affect Ball Screw Support Units?
                              Answer: Thermal expansion can impact the performance of Ball Screw Support Units, especially in high-speed applications. The floating support unit allows the ball screw to expand and contract without causing misalignment or binding, while the fixed support holds the ball screw steady. Proper support design prevents temperature-induced issues.
