Ball screw support units are essential components that contribute to the improvement of machine efficiency, precision, and reliability in various industries. These units serve as bearings connecting ball screws to drive motors, enabling high-precision and high-rigidity linear motion. There are different types of ball screw support units, including fixed-end support units, free-end support units, and floating support units. The selection of these units depends on factors such as the lead of the ball screw, load capacity, speed, and rigidity requirements.

Fixed-end support units are installed at one end of the ball screw and are designed to bear both axial and radial loads while securing the position of the ball screw. Typically equipped with preloaded adjustable angular contact ball bearings, fixed-end support units enhance axial rigidity and precision. Representative models of fixed-end support units include AK, BK, EK, FK, FKA, LK, WBK, SBK and MBK.

Free-end support units are installed at the other end of the ball screw and are designed to bear radial loads while allowing for some longitudinal variation in the ball screw. Typically equipped with deep groove ball bearings, free-end support units aim to reduce starting torque and friction. Representative models of free-end support units include AF, BF, EF, FF, LF, LFA and HF.

Ball screw support units find wide applications across various industries. For instance, they can enhance the motion precision, efficiency, and lifespan of equipment.

Ball screw support units are widely utilized across various industries, including machine tools, industrial machinery, electronic equipment, CNC machine tools, industrial robots, printing machines, packaging machines, medical equipment, conveyor machinery, and more. They are employed to achieve precise positioning, measurement, control, and motion functions.

For example, in machine tools, ball screw support units can drive tools or workpieces to move in the X, Y, and Z directions. In electronic machinery, these units may be used to drive print heads or laser heads for scanning on flat or curved surfaces. In conveyor machinery, ball screw support units are employed to drive the movement of goods or personnel in horizontal or vertical directions. The versatility of ball screw support units makes them essential components in a wide range of applications, contributing to the efficiency and performance of diverse industrial processes.

Ball screw support units are crucial components that ensure the accuracy, stability, and durability of ball screw systems. They play a vital role in enhancing the efficiency, precision, and reliability of various industries and machines that utilize ball screws for linear motion applications.

Ball screw support units are mechanical components designed for fixing and supporting ball screws. They can convert the rotary motion of a ball screw into linear motion or vice versa. The compact design of ball screw support units allows them to be installed in narrow machine spaces. Additionally, due to the preloaded nature of the bearings, there is no need for additional processing before assembly onto equipment. This reduces assembly time and enhances assembly precision.

Ball screw support units come in various categories and are identified by specific code abbreviations. They can be classified into the following types based on their form and function:

• Fixed Side Support Unit: Used to secure one end of the ball screw, preventing axial deformation or displacement during rotation. Fixed-end support units typically employ angular contact ball bearings or tapered roller bearings and are preloaded with a certain axial force to enhance the rigidity and precision of the ball screw. The code abbreviations for fixed-end support units include AK**, BK**, EK**, FK**, FKA**, LK**, WBK**, SBK**, and MBK**.
• Supported Side Support Unit (Free-end Support Unit): Used to support the other end of the ball screw, absorbing elongation or contraction changes during rotation. Floating-end support units typically employ deep groove ball bearings or cylindrical roller bearings and are designed with a certain gap or elastic element to allow some axial movement of the ball screw. The code abbreviations for floating-end support units include AF**, BF**, EF**, FF**, LF**, LFA**, and HF**.
