Optimal Gripping for Industrial Automation

Four Jaw Grippers ensure precise workpiece holding in CNC lathe operations, assembly robots, and automated machining. Their independent jaw adjustment and strong alloy steel construction accommodate a variety of part shapes and sizes, making them a perfect fit for demanding industrial applications. Factory pre-lubricated and fitted with durable dust seals, these grippers are built to thrive in both manufacturing and assembly line environments.

Engineered for Reliability and Accuracy

With a gripping force up to 2.8 kN and repeatability within 0.03 mm, these grippers provide stable, secure holding for high-load and high-precision applications. The case-hardened jaws with black oxide or nickel plating resist wear and corrosion, while a customizable ISO interface allows straightforward integration into diverse CNC and robotic systems.

FAQs of Four Jaw Grippers:

Q: How do the four independently adjustable jaws improve gripping versatility?

A: Each of the four jaws can be independently positioned, allowing secure clamping of irregular, rectangular, or custom-shaped workpieces. This enhances flexibility for gripping a wide range of component geometries in machining, assembly, or automation processes.

Q: What are the recommended operating pressures and temperatures for pneumatic models?

A: For pneumatic models, the optimal operating pressure is between 5 and 8 bar, while the temperature range is -10C to 80C. These parameters ensure reliable performance across standard industrial environments.

Q: When should I perform maintenance or lubrication on the gripper?

A: Though factory pre-lubricated, the gripper should be periodically relubricated depending on the operational environment and usage frequency. Jaw replacement is simple due to the grippers low-maintenance design and modular construction.

Q: Where can Four Jaw Grippers be installed or integrated?

A: These grippers feature a standard ISO mounting interface and are easily adaptable for CNC lathes, turning centers, assembly robots, and automated machine fixtures. Customized mounting options are available to fit unique requirements.

Q: What is the maximum load and gripping range for these grippers?

A: They can securely grasp workpieces weighing up to 120 kg and typically grip outer diameters between 80 and 160 mm, depending on the selected model and jaw configuration.

Q: How do dust protection seals benefit industrial applications?

A: The integrated dust protection seals shield internal mechanisms from particulate contamination, reducing wear and prolonging service life, even in harsh manufacturing settings.
