Description VGFR45-120
VGFR45-120 two-finger parallel pneumatic gripper for industrial automation
The VGFR45-120 pneumatic two-finger parallel gripper is designed for secure workpiece holding and precise positioning within industrial robot systems, CNC machining centres, and assembly lines. This model is widely used in metalworking, mechanical engineering, logistics, and foundry operations where stable performance under high cycle rates and dynamic loads is essential.
Design features and benefits
The toothed guide, developed on the principle of a chuck mechanism, provides increased load capacity and resistance to lateral and moment loads, significantly outperforming traditional T-slot designs in terms of service life. The wedge drive mechanism synchronises jaw motion, ensuring high repeatability (±0.02 mm) and consistent clamping force regardless of the contact point. The anodised aluminium body makes the gripper lightweight (0.9 kg) and rigid, which is critical for high-speed operations. The side pneumatic port simplifies installation in confined spaces.
Modifications and options
The base VGFR45-120 model can be enhanced with options to suit specific working conditions: IP64 dust protection cover (P), self-locking with normally open (NO) or normally closed (NC) springs, high-temperature version up to 240°C (H), and a short-stroke version (S) with 5 mm travel for miniature workpieces. Inductive and magnetic proximity sensors are available for finger position monitoring.
System integration and compatibility
For a complete solution, the VGFR45-120 base gripper can be supplemented with replaceable fingers, adapter flanges for robot or equipment mounting, and ZM-20X-A quick-change fingers for rapid changeover between different workpiece types. Compatibility with compensation modules and rotary units further expands functionality and protects the gripper from overloads.
