About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X250SCA
The AirTAC MBLC32X250SCA is a double-acting aluminum mini cylinder featuring a 32mm bore and 250mm stroke. It delivers 402 N of push force at 0.5 MPa, utilizing air to both extend and retract the Ø12 mm carbon-steel rod. A defining feature is the screw-adjustable pneumatic cushion at both ends, decelerating the piston smoothly near stroke limits to reduce impact and noise on faster moves.
This specific configuration includes a CA pivot clevis back cover that swings on a pin, making it well-suited for arcing or angular loads. The riveted rolling-packed aluminum barrel keeps the body compact, while the built-in magnet (-S) enables position detection via CMSG reed or DMSG and EMSG electronic sensor switches. The heterogeneous two-way grease-retaining piston seal ensures lasting lubrication for high-frequency cycling.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X250SCA Is Used
Carton Flap Folding
Drives folding mechanisms on case erectors where the 250mm stroke clears the carton width, while the CA pivot absorbs linkage arc and the air cushion prevents hard end-cover strikes during rapid cycling.
Pallet Diverter Arm
Pushes lightweight pallets onto a secondary conveyor line; the 402 N push force at 0.5 MPa easily moves the mass, and the adjustable cushion stops the 12mm rod smoothly at 800 mm/s.
Textile Guide Mechanism
Shifts yarn guides across a 250mm path, relying on the built-in magnet to trigger CMSG reed switches for position confirmation and the compact riveted barrel to fit tight loom frames.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X250SCA the Right Cylinder?
When sizing this 32mm bore actuator, stepping down to the 25mm bore yields 245 N push at 0.5 MPa, whereas stepping up to the 40mm bore provides 628 N. Choose this MBLC cushioned variant over the base MBL when your application runs at high speeds or cycles frequently, requiring tunable end-of-stroke deceleration that a fixed rubber bumper cannot handle. Note that the air cushion only decelerates the piston; it does not lock the rod or hold position if air pressure is lost.
With a 250mm stroke, the 12mm rod is highly susceptible to side-load bending. The CA pivot clevis on this SKU helps accommodate minor angular misalignment, but for heavy lateral loads you should use an external guide rail, an SDB pivot bracket, or switch to an MBLD double-rod cylinder. Replacement match: 32mm bore, 250mm stroke, G1/8 port, PT thread, CA back cover, magnet installed.
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 MBLC32X250SCA FAQ
At 0.5 MPa, this 32mm bore cylinder delivers 402 N push and 346 N pull. At 0.7 MPa, it provides 563 N push and 484 N pull. The maximum theoretical force is 82 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps a pocket of exhaust air to decelerate the piston smoothly near the stroke limits. You tune the needle to match your load and speed, cutting impact stress on the end covers. It is strictly a deceleration device, not a load lock or brake.
