About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X300CA
The AirTAC MBLC32X300CA is a double-acting aluminum mini cylinder engineered for a 300 mm stroke, delivering 402 N of push force and 346 N of pull force at 0.5 MPa. It features a riveted rolling-packed aluminum barrel that keeps the body compact and lightweight for tight machinery spaces, paired with a heterogeneous two-way grease-retaining piston seal that maintains lubrication over long reciprocating cycles. The carbon-steel rod is ground and plated with 20 um hard-chrome to resist scoring and extend seal life.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant incorporates a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needle lets you decelerate the piston smoothly over the 300 mm travel, absorbing kinetic energy to reduce end-cover impact and vibration on faster moves. The CA pivot back cover swings on a pin to accommodate arcing loads, which is critical for maintaining alignment on longer strokes. Note that this specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensing.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X300CA Is Used
Pallet Transfer Diverter
Actuates a sweeping diverter arm on a packaging conveyor, using the CA pivot to absorb the angular load as it pushes product into a secondary lane over the 300 mm stroke.
Textile Loom Tensioner
Positions a yarn guide bar on a textile machine, where the tunable air cushion prevents sudden snatching at stroke ends that could snap delicate threads.
Carton Flap Folder
Drives a folding mechanism on a carton erector, relying on the 402 N push force to tuck heavy cardboard flaps while the cushion softens the impact at full extension.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X300CA the Right Cylinder?
Selecting the MBLC32X300CA makes sense when your mechanism requires moderate force and a long 300 mm travel with smooth end-of-stroke deceleration. If you need less force, stepping down to the 25 mm bore drops the output to 245 N push at 0.5 MPa but saves space; stepping up to the 40 mm bore increases thrust to 628 N push at 0.5 MPa for heavier payloads. Because this cylinder uses a Ø12 mm rod over a 300 mm stroke, side-load tolerance is inherently low. You must use an external guide rail, leverage the CA pivot clevis to absorb angularity, or switch to an MBLD double-rod cylinder to prevent rod bending and premature seal wear. Remember that the adjustable air cushion only decelerates the piston near the ends—it is not a brake and will not hold the load if air pressure is lost or the valve centers.
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 MBLC32X300CA FAQ
This 32 mm bore cylinder uses a G1/8 port and a Ø12 mm rod with an M10x1.25 thread. At 0.5 MPa it provides 402 N push and 346 N pull force. At 0.7 MPa it provides 563 N push and 484 N pull. The maximum theoretical force is 82 kgf at 1.0 MPa.
The cushion is a screw-tunable needle valve at both ends that traps a small amount of exhaust air to decelerate the piston before it hits the end cover. You adjust it to match your load and speed, which reduces impact noise and wear compared to a fixed rubber bumper. It only slows the piston near the stroke ends and does not lock or hold the rod in place.
