Overview
The Thomson Saginaw ball screw linear actuator assembly (B-3-1-463) is designed to convert rotational motion into smooth, precise linear movement for industrial control and automation applications. This assembly consists of a precision ball screw and a ball nut packaged with recirculating ball bearings, delivering high-accuracy positioning with minimal internal friction and wear.
Key Features
- Ball Screw Design: Rolling elements provide a low friction coefficient (typically up to 98%), with forces distributed over multiple balls for low relative load per ball
- Precision Positioning: Capable of applying or withstanding high thrust loads with minimum internal friction and manufactured to close tolerances suitable for high-precision applications
- Reliable Operation: Recirculating ball bearing design ensures smooth, repeatable linear motion suitable for continuous-duty industrial environments
- Compact Assembly: Integrated motor and screw assembly in a self-contained package for simplified installation
- Versatile Application: Suitable for factory automation, material handling, positioning systems, and other precision motion control tasks
