Vacuum suction is a core solution for "flexible grasping" in industrial automation with four core advantages: non-damaging grasping, adaptability to multi-material/irregular workpieces, clean and environmental protection, and flexible operation. It can be adapted to different industry characteristics of workpieces (thin/thick, precision/coarse, sanitary/standard).

Resource
The Bellows Without Lock Ring Vacuum Suction Cups ZP2-J are designed for compact, precise, and adaptable automation applications. They are ideal for small components, irregular parts, and production lines with limited space.
Key Features of ZP2-J Bellows Cups Without a Lock Ring
High Flexibility
Multi-stage accordion design (2.5-layer or 3.5-layer) allows vertical stroke absorption, compensating for height differences and minor misalignments.
Ensures stable gripping on uneven or inclined surfaces.
Supports delicate or irregularly shaped workpieces without causing damage.
No Lock Ring Needed
2.5-layer models do not require a lock ring, simplifying installation and reducing assembly time.
Available in φ6mm, φ10mm, and φ15mm diameters to match different suction requirements.
Maintains reliable adhesion despite the absence of locking hardware.
Mounting Type
Designed for direct or modular integration into robotic arms and automated stations.
Compact structure fits tight spaces on production lines.
Supports efficient material handling in electronics, injection molding, and small metalworking industries.
Material Variety
The Bellows Without Lock Ring Vacuum Suction Cups ZP2-J is manufactured using high-quality silicone, rubber, or polyurethane (PU), offering a combination of exceptional abrasion resistance and flexibility.
Compatible with cleanroom or anti-static environments for electronics manufacturing.
Ensures long-term durability under frequent cycles, maintaining consistent vacuum performance.
What is the difference between ZP2-J and ZP2-ZJ?
ZP2-J
Type: Multi-bellows Bellows Without Lock Ring Vacuum Suction Cups ZP2-J
Lock Ring: Optional; 2.5-layer models do not require a lock ring
Sizes: 2.5-layer (φ6mm, φ10mm, φ15mm), 3.5-layer (φ9mm, φ14mm, φ16mm, φ25mm, φ30mm)
Applications: Works well on inclined surfaces or limited buffer space; ideal for small electronics, injection-molded parts, and compact metal components
Flexibility: High vertical stroke absorption due to accordion design
Mounting: Compact, easy integration into robotic arms and automated stations
ZP2-ZJ
Type: Single-stage or double-stage bellows vacuum cup with a lock ring
Lock Ring: Required for secure mounting
Sizes: Typically larger diameters than ZP2-J; designed for heavier or larger workpieces
Applications: Suitable for slightly larger, heavier, or more rigid objects; commonly used in industrial automation where stability and secure attachment are critical
Flexibility: Moderate stroke absorption; focus on reliable holding rather than extreme vertical compensation
Mounting: Requires lock ring for secure attachment, compatible with standard mounting hardware
