About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X300SU
The AirTAC MBLC32X300SU is a double-acting aluminum mini cylinder built for compact spaces requiring a 300 mm stroke. It delivers 402 N of push force and 346 N of pull force at 0.5 MPa. Unlike the base MBL, this variant features a screw-adjustable pneumatic cushion at both ends. You tune the needle to smoothly decelerate the piston near stroke limits, cutting impact and vibration on fast moves.
This model includes a built-in magnet (the S code) for position detection with CMSG, DMSG, or EMSG sensor switches. The U code denotes a rigid flat-end back cover. To save space and weight, it uses a riveted rolling-packed aluminum barrel rather than a rebuildable tie-rod design. The carbon-steel rod features a 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for lasting lubrication.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X300SU Is Used
Textile Loom Let-off
Drives the 300 mm tensioning stroke on a weaving let-off mechanism, using the adjustable cushion to prevent yarn snap on rapid 402 N pulls.
PCB Unstacker Arm
Lifts populated boards from a magazine, relying on the tunable end-cushion to stop the 32 mm bore smoothly without shaking delicate components.
Carton Flap Folder
Folds packaging flaps on a continuous flow wrapper, where the compact riveted barrel fits tight side rails and the magnet confirms stroke ends.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X300SU the Right Cylinder?
Stepping down to the 25 mm bore drops the push force to 245 N at 0.5 MPa, while moving up to the 40 mm bore increases it to 628 N. Choose this MBLC over the fixed-bumper MBL when cycling quickly or moving a heavier mass that needs tunable end-of-stroke deceleration. Note that the air cushion only slows the piston near the ends; it is not a load lock. If the air supply drops, the rod drifts, so fit an external rod lock for position holding.
For replacements, match the 32 mm bore, 300 mm stroke, G1/8 port, and M10x1.25 rod-end thread. This SKU uses the default PT tapered port thread, a U flat-end back cover, and an S magnet. Because the stroke is 300 mm, the 12 mm rod has low side-load tolerance. Prevent rod bending on long strokes by using an external guide, a CA or SDB pivot mount, 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 MBLC32X300SU FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N push and 346 N pull force. At 0.7 MPa, it provides 563 N push. The maximum theoretical force is 82 kgf at 1.0 MPa.
You tune a screw needle at both ends to match your load and speed. It traps exhaust air to decelerate the piston smoothly near the stroke limits, reducing end-cover impact and noise compared to the fixed rubber bumper of the standard MBL.
