Gripper Jaws/Suction Cups: Weight Capacity 0.1-50 kg

Q: What factors determine whether to use gripper jaws or suction cups?

Gripper jaws are preferred for irregular shapes, heavy objects, or applications requiring precise force control. Suction cups are ideal for smooth, non-porous surfaces like glass, metal sheets, or packaging materials where surface contact is sufficient.

Q: How do I maintain gripper jaws and suction cups?

Regular inspection for wear, cleaning of contact surfaces, lubrication of moving parts (for gripper jaws), and checking vacuum seals and lines (for suction cups). Replace worn components according to manufacturer specifications.

Component Specifications

Definition

Gripper jaws are mechanical components designed to grasp, hold, and release objects through physical contact, typically using friction or form closure. Suction cups are pneumatic components that create vacuum pressure to adhere to smooth, non-porous surfaces for material handling. Both are critical sub-components of robotic end-effectors (grippers/suction heads) used in industrial automation for pick-and-place, assembly, and packaging operations.

Working Principle

Gripper jaws operate through mechanical actuation (pneumatic, electric, or hydraulic) to apply controlled force for grasping objects. Suction cups function by creating a vacuum seal against a surface; when vacuum pressure is applied, atmospheric pressure creates holding force. Both systems integrate with robotic controllers for precise positioning and force control during material handling tasks.

Materials

Gripper jaws: Aluminum alloy (6061-T6), hardened steel (AISI 4140), engineering plastics (POM, PA6-GF30), polyurethane for soft gripping surfaces. Suction cups: Nitrile rubber (NBR), silicone, polyurethane, fluorocarbon rubber for chemical resistance. Mounting hardware: Stainless steel (AISI 304/316).
