SMC ZP3E-T80BMS-B12 – ZP3E Series High Rigidity Vacuum Pad, Bellows Type with Ribs & Groove, Vertical Vacuum Inlet with Adapter

The SMC ZP3E-T80BMS-B12 is a high-rigidity vacuum suction cup from the ZP3E series, engineered for stable, repeatable handling of uneven, curved, or irregular workpieces in automated manufacturing and material handling systems. Featuring a bellows-type pad with ribs and groove, this vacuum pad delivers enhanced sealing performance on non-flat surfaces while maintaining high lateral and torsional rigidity for precise positioning.

Key Technical Features

• Series: ZP3E – High rigidity vacuum pad with improved suction stability and ease of removal
• Pad Form: Bellows type with ribs and groove – optimized for conforming to curved, warped, or textured surfaces while resisting lateral shear forces
• Pad Diameter: 80 mm – provides a large effective suction area for reliable lifting and transfer of medium to large workpieces
• Pad Material: NBR (Nitrile Butadiene Rubber) – offers excellent resistance to oils, greases, and general industrial environments; also available in mark-free NBR, silicone, urethane, and FKM for specialized applications
• Mounting Thread: Male and female thread options – enables flexible integration into custom mounting blocks, grippers, or end-of-arm tooling
• Vacuum Inlet Direction: Vertical entry with integrated adapter – simplifies hose routing and reduces profile height in space-constrained applications
• Vacuum Inlet Type: Threaded connection (M5 or equivalent, depending on model) – ensures secure, leak-free connection to vacuum lines or manifold systems
• Buffer Type: Non-rotating buffer with bushing – absorbs misalignment and vertical shock loads during pick-and-place cycles
• Buffer Stroke Options: 10 mm, 30 mm, 50 mm – selectable stroke allows tuning of compliance and damping characteristics for specific workpiece dynamics

Performance & Application Advantages

• Improved Suction Stability: Grooved and ribbed bellows design enhances sealing on uneven or slightly contaminated surfaces, reducing drop-out risk in high-speed automation.
• Compact, Low-Profile Design: The ZP3E series features a shortened buffer body compared to standard ZP pads, minimizing overall height and enabling use in tight vertical spaces.
• Reduced Mounting Hardware: Single mounting screw design simplifies installation and reduces part count, improving assembly efficiency and serviceability.
• Separable Pad & Metal Components: Rubber pad and metal body can be disassembled for separate disposal or replacement, supporting sustainability and reducing lifecycle costs.
• High Rigidity Construction: Optimized internal structure provides superior resistance to deformation under load, maintaining consistent suction position and orientation during transfer.

Typical Applications

• Automated pick-and-place of sheet metal, glass, or composite panels
• Handling of curved or domed workpieces in automotive, appliance, and electronics assembly
• Robotic palletizing and depalletizing of boxes, trays, and containers
• Conveyor transfer systems requiring high positional repeatability and shock absorption
• Applications where oil mist, light contamination, or surface irregularities are present

Material & Compliance

• Standard pad material: NBR (oil and abrasion resistant)
• Optional materials: Silicone (high/low temp, FDA-compliant), Urethane (high wear resistance), FKM (chemical/oil resistance), Mark-free NBR (for sensitive surfaces)
• RoHS compliant – suitable for use in regulated industrial environments

Integration & Selection Guidance

• Select pad diameter based on required theoretical lifting force at operating vacuum level (e.g., ?40 kPa to ?80 kPa)
• Use bellows with ribs and groove for workpieces with moderate curvature, surface texture, or minor warpage
• Specify buffer stroke (10/30/50 mm) based on expected misalignment, vertical travel, and damping requirements
• Verify compatibility with vacuum generator or ejector flow rate to ensure adequate evacuation time in cycle
• Always perform a real-world suction test with actual workpiece and vacuum system before full deployment
