About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X40CA
The AirTAC MBLC32X40CA is a double-acting aluminum mini cylinder engineered for compact actuation where end-of-stroke impact must be controlled. It generates 402 N of push force and 346 N of pull force at 0.5 MPa. The 40 mm stroke is well suited to short, rapid positioning tasks. Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic cushion at both ends. You tune the needle to decelerate the piston smoothly, minimizing noise and protecting the end covers on fast moves.
This SKU includes a CA pivot back cover, allowing the body to swing on a pin to accommodate arcing or angular loads. It uses a Ø12 mm carbon-steel rod with 20 µm hard-chrome plating and a heterogeneous two-way grease-retaining piston seal inside a riveted rolling-packed aluminum barrel. Because this specific model lacks the -S suffix, it has no built-in magnet and cannot accept a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X40CA Is Used
Packaging Flap Diverter
Uses the 402 N push force and 40 mm stroke to rapidly redirect cardboard cartons on a packaging line, relying on the CA pivot to absorb angular load as the arm swings.
Textile Yarn Guide
Shifts a yarn guide back and forth across a beam, where the tunable air cushion prevents sudden jerks that would snap delicate threads at high cycling speeds.
Bin Gate Actuator
Opens and closes a small hopper gate for granular materials, using the short 40 mm stroke and pivot mount to handle the off-center weight of the swinging door.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X40CA the Right Cylinder?
Choose this 32 mm bore when you need approximately 402 N of push force at 0.5 MPa. If your application is lighter, stepping down to the 25 mm bore yields 245 N of push force. For heavier loads, stepping up to the 40 mm bore provides 628 N. The CA clevis mount is essential here if your mechanism generates side-arcing forces during travel. Note that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake. If you need to hold position without live air pressure, you must add an external rod lock or pilot-operated check valve. Replacement matches require a 32 mm bore, 40 mm stroke, G1/8 port, PT thread, and CA pivot cover.
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 MBLC32X40CA FAQ
This 32 mm bore cylinder uses a G1/8 port and a Ø12 mm rod. At 0.5 MPa it provides 402 N push and 346 N pull. At 0.7 MPa it provides 563 N push. The maximum theoretical force is 82 kgf at 1.0 MPa.
No. Because the model code lacks the S suffix, this SKU is manufactured without a built-in piston magnet. You cannot mount a CMSG reed switch or DMSG/EMSG electronic sensor to it. For position detection, you need an MBLC32X40S variant.
