# TWH pneumatic stopper cylinder for Conveyor Automation Date: 2026-05-09 Categories: Pneumatic Cylinder URL: https://homipneu.com/twh-pneumatic-stopper-cylinder.html ## Product Summary TWH Series pneumatic stopper cylinders are designed for conveyor stopping, pallet positioning, and transfer line automation. Compatible with Airtac TWH/TWM Series, they are commonly used in automated assembly lines, packaging machinery, sorting equipment, and pallet conveyor systems where stable stopping, buffering, and repeatable positioning are required. The widened piston rod structure supports improved impact resistance, while shockless stopper and self-locking configurations help reduce rebound during workpiece stopping. With aluminum alloy construction, ISO standard mounting, and practical integration into conveyor automation equipment, the TWH Series is suitable for demanding industrial transfer applications. OEM and ODM customization services are supported. ## Specifications Parameter Description Product Name Pneumatic Stopper Cylinder Series TWH Series Related Model TWM Series Cylinder Type Stopper Cylinder Action Type Double Acting Working Medium Clean Air Bore Size 20 / 25 / 32 / 40 / 50 / 63 / 80 mm Stroke Application Dependent Body Material Aluminum Alloy Structure Type Lever Type / Roller Type Stopper Structure Shock Absorption Hydraulic Buffer / Shockless Stopper Structure Self-Locking Function Available on selected lever roller types Mounting Type ISO Standard Mounting Compatible with Airtac TWH/TWM Series Applications Conveyor Line / Pallet Stopper / Transfer System ## How to order ![How to order TWH pneumatic stopper cylinder](https://homipneu.com/wp-content/uploads/2026/05/20260516192306217748-900x354.webp) ### Product Features **Conveyor Stopper Cylinder Design**The TWH Series is designed for stopping pallets, fixtures, and workpieces on conveyor lines and automated transfer systems. **Shockless Stopping Performance**The stopper structure helps reduce impact during workpiece stopping, making it suitable for automated lines requiring stable positioning. **Heavy-Duty Impact Resistance**A widened piston rod structure helps improve resistance to side impact and repeated stopping loads in conveyor applications. **Hydraulic Buffer Option**Selected configurations can use hydraulic buffering to absorb impact energy during high-frequency transfer line operation. **Self-Locking Stopper Structure**Lever roller types can be equipped with a self-locking structure to reduce rebound after the workpiece is stopped. **Suitable Replacement for Airtac TWH/TWM Series**Designed for pneumatic stopper cylinder applications requiring replacement for Airtac TWH/TWM Series models. **Industrial Transfer Line Integration**ISO standard mounting supports practical installation into conveyor machinery, pallet transfer systems, and automated production lines. ### Applications **Conveyor Stopper Systems**Used to stop pallets, carriers, and workpieces on automated conveyor lines. **Pallet Transfer Lines**Suitable for positioning pallets before assembly, inspection, loading, or unloading stations. **Automated Assembly Equipment**Applied in production lines where accurate stopping and positioning are required. **Packaging and Sorting Machinery**Used in automated packaging, sorting, and material transfer systems. **Industrial Handling Systems**Suitable for machinery requiring repeated stopping, buffering, and workpiece positioning. ### Why Choose HOMIPNEU - Stable manufacturing quality for pneumatic stopper cylinders - Practical design for conveyor and pallet transfer applications - Shockless stopper structures for reduced workpiece impact - Support for heavy-duty and self-locking configurations - ISO standard mounting for easier machine integration - Custom bore, stroke, and stopper structure support - Reliable supply for automation equipment manufacturers - Export packaging and branding support ### FAQ **Is the TWH Series interchangeable with Airtac TWH/TWM Series?**Yes, for this product page, TWH and TWM are treated as the same model range.
