Classic 4 Centric SoftGripper
SKU
SG-C-F4-160
Four-finger centric pneumatic soft gripper for compliant, food-grade handling of delicate or irregular products with radial automatic centering.
Sample image only. Product may differ
The Four-Finger Centric SoftGripper is a pneumatically actuated, compliant gripper designed for radial, symmetric enclosure of delicate and irregular products. Four evenly spaced fingers move inward toward the center point, surrounding the object and automatically centering it during the gripping cycle.
Compared to three-finger centric designs, the four-finger configuration increases surface contact and improves stability during transfer. The elastomer fingers conform to product geometry, distributing gripping forces evenly and reducing pressure concentrations.
This geometry is suited for round, irregular, or loosely positioned items where automatic centering and multi-point contact improve repeatability.

Typical Objects Handled
The four-finger radial configuration increases contact coverage compared to three-finger versions, improving stability for larger or less uniform products. It is well suited for fruits like strawberries, oranges and figs, as well as other delicate items like eggs and small vials.
Best Fit Applications
- Food and beverage automation handling round or irregular products
- Hygienic production environments requiring symmetric multi-point enclosure
- Pick-and-place of cylindrical or loosely positioned objects
- Applications requiring automatic object centering during gripping
- Cobot-based automation cells handling delicate or deformable items
For applications requiring lateral clamping instead of radial enclosure, reference the Four-Finger Parallel SoftGripper. For smaller diameter objects with reduced contact coverage, reference the Three-Finger Centric SoftGripper.
