    CM-30T-SERVO

    The SEALS CM-30T-SERVO adopts a high-precision, low-reaction-force servo nut runner that delivers detailed fastening data for every screw, ensuring speed, stability, and process transparency. When fastening parameters deviate from preset values, the system provides real-time alerts and generates a complete, traceable report to support quality control and auditing. This system supports multi-step fastening actions programmed into a single job—ideal for complex tasks that conventional electric screwdrivers cannot perform. Additionally, it allows precise control of rotation angle and speed to meet specific tightening requirements. The screw jaw is custom-built based on the screw type and working environment, ensuring reliable positioning and stable operation. The lever-activated design meets ergonomic and labor-saving standards; the screwdriver automatically initiates fastening with a single press of the lever. When paired with the TA-300 torque reaction arm, the tool maintains a stable vertical alignment, improves torque accuracy, and reduces operator fatigue. This setup is especially effective for high-torque shut-off applications where consistent torque control is essential.

  • TR-650M Multi-Drive Fastening System with torque reaction arm
    TR-650M Multi-Drive Fastening System with torque reaction arm
    TR-650M

    SEALS, TR-650M, Multi-Drive Fastening System, increases screw fastening productivity and quality by fastening more than two screws at the same time. By installing two or more screwdrivers in torque reaction arm, TR-650Multi-Driver not only increase efficiency but also enhance fastening balancing. This solves the problem of fastening sequence for multi screws in the sealing cover of container chamber, cylinder, tank, housing, etc. The multi screw is fastening simultaneously so that there will be no problem the first screw cause the gap or relevant issue. By the handling bar, it is easy to aim at the screw holes. Meanwhile, there is a lever trigger in the handling par to control the fastening process. The torque reaction and tool supporting arm TR-650 allow weight less operation experience and flexible aimming movement.
