About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X250U
The AirTAC MBLC32X250U is a double-acting aluminum mini cylinder featuring a 32mm bore and 250mm stroke. It generates 402 N of push force and 346 N of pull force at 0.5 MPa. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot host a CMSG, DMSG, or EMSG position sensor. The riveted rolling-packed aluminum barrel keeps the body compact for tight machine layouts, while the 20 µm hard-chrome plated carbon-steel rod resists wear.
This model relies on a screw-adjustable pneumatic air cushion at both stroke ends rather than a fixed rubber bumper. Turning the cushion needle lets you dial in end-of-stroke deceleration to match heavier or faster 250mm traverses, reducing impact stress on the end covers. Note that the cushion only slows the piston near the ends; it is not a load lock and will not hold the rod in place if air pressure drops.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X250U Is Used
Packaging Conveyor Diverter
Pushes cartons across a 250mm belt lane with 402 N at 0.5 MPa, using the adjustable cushion to halt the diverter arm smoothly without jarring the packing line.
PCB Router Clamp
Secures small PCB routing fixtures over a 250mm gap; the riveted aluminum body fits tight electronics cells while the cushion prevents end-cap shock on fast clamps.
Textile Bobbin Ejector
Kicks spun bobbins out of a winding cradle, relying on the 346 N pull force to retract the 12mm rod cleanly before the next yarn spool loads.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X250U the Right Cylinder?
Stepping down to the 25mm bore drops the output to 245 N push at 0.5 MPa, whereas moving up to the 40mm bore increases it to 628 N. Choose this MBLC version over the base MBL when your cycle speeds or moved mass exceed what a fixed rubber bumper can absorb. For replacements, match the 32mm bore, 250mm stroke, G1/8 port, PT thread, U flat-end back cover, and no magnet. At 250mm, the 12mm rod has limited side-load tolerance; for arcing or lateral loads, use an external guide, a CA/SDB pivot, or the MBLD double-rod type.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X250U FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, push increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
A screw needle at both ends lets you tune the pneumatic cushioning to match your load and speed. This decelerates the piston near the end caps, cutting vibration and noise on fast 250mm strokes. It only decelerates near the ends and does not lock or hold the load without air pressure.
