INDUSTRY COMPONENT

Gripper Jaws/Fingers

Gripper jaws or fingers are the contact components of robotic grippers that directly handle objects in automated systems.

Component Specifications

Definition
Gripper jaws, also known as fingers, are the interchangeable or adjustable contact surfaces of robotic grippers designed to securely grasp, hold, and manipulate objects during automated material handling, assembly, or packaging operations. They interface directly with workpieces and are critical for precision, repeatability, and adaptability in industrial automation.
Working Principle
Gripper jaws operate by applying mechanical force through pneumatic, hydraulic, or electric actuation to clamp onto objects. They convert the gripper's linear or rotational motion into secure holding force, often using friction, form-fit, or vacuum-assisted methods to prevent slippage or damage to the workpiece.
Materials
Common materials include aluminum alloys (e.g., 6061-T6) for lightweight applications, hardened steel (e.g., AISI 4140) for durability, polyurethane or silicone for soft gripping, and engineering plastics like PEEK for chemical resistance. Coatings such as titanium nitride or diamond-like carbon may be applied to reduce wear.
