• Better for mid-range actuation requiring moderate stroke and robust mounting options.
• Caution: Ensure PT 3/8 port and 8 mm tubing are compatible with your existing supply lines.

TAILONZ PNEUMATIC 25mm Bore 50mm Stroke Cylinder

Check Price on Amazon

Best for small, space-constrained applications where a double-acting action is required. With a 25 mm bore and 50 mm stroke, this model is ideal for light-duty actuations and compact automation tasks.

• Choose this if you need a tiny footprint with straightforward PT1/8 porting.
• Caution: Lower bore size may limit maximum force compared to larger cylinders.

Baomain SC 63 x 250 Pneumatic Cylinder

Check Price on Amazon

This model features a longer 250 mm stroke and a 63 mm bore, designed for applications needing extended travel in a compact body. It includes an M16x1.5 threaded rod and PT 3/8 port, with two push-in fittings for quick tubing connections.

• Best for vertical or horizontal linear actuations requiring extra stroke length.
• Caution: Longer stroke can demand more mounting stability to prevent misalignment.

Baomain SC 63 x 300 Pneumatic Cylinder

Check Price on Amazon

Best for extended travel in automation lines with mounting flexibility. The 11.81″ stroke and 63 mm bore allow substantial linear motion while maintaining a compact footprint. It includes mounting hardware and push-in fittings.

• Better for processes that require longer reach without redesigning the system.
• Caution: The longer cylinder needs stable mounting to minimize bending moments on the rod.

Baomain SC 63 x 400 Pneumatic Cylinder

Check Price on Amazon

Best for demanding long-stroke applications requiring robust performance. With a 400 mm stroke and a 63 mm bore, this model is suited for conveyors, pick-and-place, or linear transfer tasks where extended travel is essential.

• Choose this for high-stroke needs in compact machinery layouts.
• Caution: Ensure the additional stroke does not interfere with adjacent components or clearances.

Buying Guide: How To Choose Your 2 Way Pneumatic Cylinder

What bore and stroke should I choose?

The bore determines available force; a larger bore yields more push force. Stroke length defines travel distance. For high-speed, short-throw tasks, a smaller bore and shorter stroke may suffice. For longer travel or heavier loads, opt for bigger bore and longer stroke models.

Which port size matters?

Port size affects compatibility with your air supply lines. PT 1/4 and PT 3/8 are common. Ensure your tubing fits snugly and that fittings are included or readily available for quick installation.

What about mounting and accessories?

Many models include mounting brackets, end caps, or base options. Consider whether you need CY feet, CB bases, or dual-ear mounting to achieve secure alignment in your setup.

Double-acting vs single-rod design

Double-acting cylinders provide both forward and return force, suitable for continuous cycle operations. A single-rod design keeps weight down and is often adequate for simple push-pull tasks.

Material and durability considerations

Most cylinders use aluminum bodies with stainless steel rods. Check corrosion resistance if the environment is humid or involves exposure to chemicals. Self-lubricating bearings reduce maintenance in stationary setups.

Practical setup tips

• Plan your valve and cylinder orientation to minimize side loads on the rod.
• Use push-in fittings compatible with your tubing diameter to simplify installation.
• Test actuation at low pressure to verify smooth operation and alignment before full use.

FAQ

• What is a 2-way pneumatic cylinder used for?
  
  They provide controlled linear motion in automation tasks, often acting as actuators driven by compressed air for forward and return strokes.
• How do I determine the right bore size?
  
  Compare required force with the cylinder’s theoretical push capacity; larger loads need larger bore for adequate force.
• Are push-in fittings universal?
  
  Push-in fittings are common but verify tubing outer diameter and threading to ensure compatibility with your system.
• Is longer stroke always better?
  
  No. Longer strokes enable more travel but require more space and stable mounting to prevent misalignment.
• Can I retrofit a cylinder with different port sizes?
  
  Adapters are sometimes available, but verify compatibility with your pneumatic supply and space constraints.
• What maintenance is required?
  
  Most cylinders need minimal maintenance due to self-lubricating bearings; periodic checks for leaks and alignment are recommended.
