CRG pneumatic needle grippers are ideal for handling textiles, fabrics, carpets, and other penetrable materials, particularly porous workpieces that cannot be handled reliably with vacuum cups.
These EOAT needle grippers are suitable for textile, food-processing, and other automation applications. Compatible fittings are available for easy integration into robotic gripper systems.
Our catalog includes four needle-gripper models. Leave your email and one of our experienced engineers will contact you within 24 hours.

A pneumatic needle gripper uses controlled pins to penetrate and hold porous or flexible material that is difficult to handle with vacuum. Typical applications include textiles, insulation, foam and layered technical materials.
Confirm that controlled needle penetration is acceptable and that the material has enough structure to retain the pins during acceleration.
Match the number, angle and penetration depth of the needles to material thickness, density, layer structure and allowable penetration.
Check whether the material needs a support surface, stripping action or multiple grippers to prevent sagging, tearing or rotation.
Confirm operating pressure, cycle time, retraction reliability, mounting orientation and whether material-presence feedback is required.
Use controlled penetration for porous, fibrous or air-permeable materials where suction cannot establish a stable seal.
Use suction when the surface can seal reliably and penetration or visible pin marks are not acceptable.
These application details help define the needle arrangement, stroke, quantity and EOAT layout.
For non-porous surfaces, compare a vacuum gripper. For defined mechanical grip points, review CRG pneumatic finger grippers.
Needle grippers are commonly used for textiles, foam, insulation, carpets and other penetrable porous materials. Suitability should be confirmed with the actual material.
The pins penetrate the material, so small holes or marks may remain. Penetration depth, needle angle and pickup location should be tested against the product requirement.
The quantity depends on part size, stiffness, weight distribution, acceleration and allowable sag. Large flexible sheets may require several pickup points.
Send material samples or specifications, dimensions, thickness range, weight, pickup orientation, cycle time, robot interface and any mark limitations.
Send the material, thickness, part size and pickup conditions for a practical recommendation.
