PTM Three-Pivot-Finger Gripper Series DSG

Powerful, Precise, and Adaptable for Complex Clamping Tasks

The PTM DSG series of three-pivot-finger grippers sets a new benchmark in precision clamping technology. Designed for demanding industrial applications, these grippers offer unmatched versatility, high clamping force, and delicate handling of sensitive workpieces – all while keeping tooling times and maintenance to a minimum.

At the core of the DSG series lies the distinctive three-pivot-finger system, with fingers arranged 120° apart. This configuration allows rotational movement of up to 180°, enabling the gripping of various geometrically similar yet differently sized components without needing to frequently swap clamping jaws.

Thanks to the exceptionally large clamping stroke, the DSG gripper adapts quickly to a wide range of workpiece sizes. The clamping jaws are easily replaceable, and in many cases, unnecessary due to the system’s broad clamping range—delivering significant savings in setup and tooling time.

Whether you need robust clamping force or a gentle touch for deformation-sensitive parts, the DSG series delivers. The ability to fine-tune clamping force ensures that even delicate components are securely held without damage.

Key technical specifications:

• Torque range: 6.5 Nm to 585 Nm
• Available in 12 types with numerous variant options
• Large, adjustable clamping strokes with fixed stop control
• Pneumatically driven using 4 motor variants and adaptable gearing
• Optional features:
• EX Certificate (94/9/EC)
• Electronic end position monitoring
• Mounting flange & brackets
• External sealing options

Built with hard-coated aluminum housing, the DSG grippers are both lightweight and durable. Their minimal air consumption and maintenance-free drives reduce operational costs while offering spray-water protection—making them ideal for harsh industrial environments.
