Handling cylindrical, spherical, or irregular parts often exposes the limitations of conventional 2-jaw parallel grippers and vacuum suction cups—resulting in off-center placement, clamping slippage, or dropped components during rapid acceleration.
The ZEKEEP 3-Jaw Pneumatic Gripper addresses this with a synchronized 120° radial mechanism. Driven by an industrial-grade pneumatic cylinder, its three extended high-rigidity metal fingers open and close synchronously to provide true concentric self-centering, locking target parts firmly in place for high-speed automated machine tending and assembly.
True 3-Point Concentric Self-Centering: Three jaws spaced evenly at 120° close synchronously toward the center axis, automatically correcting incoming part misalignment without requiring complex vision offsets.
Extended Encirclement Metal Fingers: Formed from high-tensile structural metal, the extended fingers provide deep-reach capability and geometric encirclement, supporting both external gripping (OD clamping) and internal expansion (ID gripping).
Direct Pneumatic Actuation & Fast Response: Delivers rapid millisecond-level opening/closing cycles with smooth pneumatic damping. Clamping force can be modulated directly via air pressure regulation.
Superior Torsional Stability: The 3-point contact geometry provides multi-directional restraint, counteracting rotational inertia and side forces far better than 2-point parallel grippers during high-speed robotic maneuvers.
Turnkey Robotic Flange Adapter: Features a standardized, offset aluminum/steel mounting bracket for direct attachment to ZEKEEP robotic arms and standard industrial tool flanges.
