Safety couplings from SUNG-IL MACHINERY CO., LTD are designed to ensure smooth and reliable power transmission while protecting machinery from overload damage under high torque conditions.

Why Sung-Il Machinery Safety Coupling?
In industrial automation and motion control, safety couplings are critical for protecting machinery from overload damage while ensuring efficient power transfer. Traditional couplings transmit torque and compensate for shaft misalignment, while torque limiters disengage when overload occurs. A safety coupling combines both functions into one compact design—delivering smooth motion, overload protection, and reliable performance.

Key Product Features
• Wide range of preset torque values: Available in multiple configurations to meet different torque requirements.
• Misalignment absorption: Plate springs in the disk coupling type provide excellent compensation for angular and axial misalignment.
• Easy torque adjustment: An adjusting nut and built-in spring pressure indicator make setup simple and precise.
• Flexible assembly options: Designed to suit ...
... various shaft clamping methods and installation conditions.
These features ensure that Sung-il Machinery safety couplings provide both versatility and dependability in demanding industrial environments.

Operating Principle
The safety coupling works on a simple but highly effective mechanism. When torque exceeds the preset disengagement value, balls fixed in V-shaped pockets of the ball plate are pushed out. This forces the ball guide away from the plate, causing the coupling section and the main hub to disengage. At this point, the coupling enters idle operation, instantly cutting off motion. This prevents overload torque from being transmitted further into the system, thereby protecting motors, gearboxes, and other sensitive machine components from damage.

Applications and Benefits
Sung-il Machinery safety couplings are widely used in:
• Robotics and factory automation systems
• CNC machinery and precision equipment
• High-torque industrial applications
By combining motion transmission with torque limiting, these couplings improve productivity, extend equipment lifespan, and reduce costly downtime caused by mechanical failure.
