Safety and Reliability
The MDF jackshaft drives prioritize safety with an integrated safety catch device that operates independently of position and speed, ensuring maintenance-free and wear-resistant performance. Thermal protection in the motor windings further enhances reliability, while high-duty motor cycles are standard, with custom options available for varying protection classes and hollow shaft diameters.
Precision and Performance
Designed for precision, the roll-formed worm shaft allows for more accurate tolerances and improved performance. Self-aligning bearings enhance smooth operation, and end position settings can be adjusted using an electronic absolute encoder or mechanical limit switch to ensure optimal functionality.
Ease of Use and Customization
The drives are user-friendly, featuring emergency operation options with either a hand crank (1-sided or 2-sided) or hand chain, and allow for straightforward conversion from crank to chain. Plug-in connections and external control options provide flexibility, while custom versions are available for varying voltages, frequencies, and motor speeds to meet specific industrial needs.
Technical Specifications
With dimensions between center lines at 5.71 or 4.72 inches, the MDF jackshaft drives can handle diverse applications. The powerful system operates on a 240V/480V, 60Hz 3-phase power supply, and supports a control voltage of 24V-DC, with custom solutions available upon request.
