About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X125CA
The AirTAC MBLC32X125CA is a compact double-acting aluminum mini cylinder featuring a screw-adjustable pneumatic cushion at both ends. Delivering 402 N of push force and 346 N of pull force at 0.5 MPa, this 32 mm bore unit is built for fast, repetitive motion where a fixed rubber bumper would fail. The 125 mm stroke provides ample travel for intermediate part ejection or positioning tasks.
This SKU uses a CA pivot clevis back cover that swings on a pin to absorb arcing angular loads, distinguishing it from rigid flat-end mounts. The body utilizes a riveted rolling-packed aluminum barrel for a lightweight footprint, while the Ø12 mm carbon-steel rod features 20 µm hard-chrome plating to resist scoring. Note that this specific configuration lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors without changing the model.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X125CA Is Used
Pallet Diverter Arms
Uses the CA pivot mount to swing packages between parallel conveyor lines, relying on the 402 N thrust and tunable cushion to halt the 125 mm stroke smoothly without jarring the packaging.
PCB Router Ejection
Pushes depaneled circuit boards out of a routing station, where the adjustable end-of-stroke deceleration prevents fragile components from bouncing upon release.
Tote Stacking Mechanism
Indexes plastic totes at a packing cell, utilizing the 125 mm stroke to align containers while the pneumatic cushion minimizes shock on the end covers during rapid cycling.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X125CA the Right Cylinder?
Select this 32 mm bore when an application demands 402 N of thrust at 0.5 MPa alongside arcing movement that requires the CA pivot mount. If your task needs less force, step down to the 25 mm bore offering 245 N; if you require more clamping power, step up to the 40 mm bore providing 628 N. Choose this MBLC variant over the base MBL when cycling speeds are high enough that the fixed bumper cannot adequately absorb the kinetic energy.
Because this SKU omits the -S suffix, no position sensor is fitted. If rod drift occurs when air is lost or the valve centers, remember the adjustable air cushion only decelerates the piston near the stroke ends—it is not a locking brake. For position holding without live air, an external rod lock or pilot-operated check valve is required. This cylinder uses a G1/8 port and M10x1.25 rod-end thread with PT piping.
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 MBLC32X125CA FAQ
At 0.5 MPa it provides 402 N push and 346 N pull force. At 0.7 MPa it yields 563 N push and 484 N pull. The maximum theoretical force is 82 kgf at 1.0 MPa. This 32 mm bore cylinder uses a G1/8 port and an M10x1.25 rod-end thread.
A screw-tunable needle at both ends traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. You dial the needle to match the load and speed, which cuts impact noise and vibration. It functions only to slow the rod near the ends and does not lock or hold the load in place.
