High precision ball screw linear actuators are mechanical devices used to convert rotational motion into linear motion with high accuracy and repeatability. These actuators are commonly used in applications requiring precise positioning and control, such as CNC machines, robotic systems, medical devices, and semiconductor manufacturing equipment.

Here’s a breakdown of the key components and benefits of high precision ball screw linear actuators: Key Components:

Ball Screw:Converts rotational motion to linear motion. Consists of a threaded shaft and a nut with ball bearings riding in the helical grooves.
Nut:Engages with the ball screw to translate rotary motion into linear motion. Contains recirculating ball bearings to reduce friction and wear.
Motor: Powers the rotation of the ball screw. Can be a stepper motor, servo motor, or other types of motors depending on the application.
Linear Guide: Provides support and guidance for the linear motion. Ensures smooth and accurate movement along the desired path.
Housing/Frame: Encapsulates and supports the components of the actuator. Provides structural stability.
Coupling: Connects the motor to the ball screw. Allows for the transfer of motion with minimal backlash.

Today, here we introduce one of our screw type linear modules TMS65 for general environment as follows:

  3. Medical Devices:Used in devices requiring accurate motion control, such as surgical robots and imaging equipment.

  4. Semiconductor Manufacturing:Essential for positioning wafers and other components with high precision.

  5. Optical Equipment:Used in positioning lenses and other optical components accurately.

Selection Criteria: When selecting linear modules, consider the following factors:

  1. Stroke Length:Determine the required travel distance for your application.

  2. Load Capacity:Ensure the actuator can handle the maximum load.

  3. Speed and Acceleration:Match the actuator’s capabilities with the application’s speed and acceleration requirements.

  4. Resolution and Repeatability:Ensure the actuator meets the desired precision specifications.

  5. Environmental Conditions:Consider factors such as temperature, humidity, and potential exposure to contaminants.

  6. Mounting and Size Constraints:Ensure the actuator fits within your spatial constraints and mounting requirements.

By carefully considering these factors and the specific needs of your application, you can select a high precision ball screw linear actuator that provides reliable and accurate performance.
