About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X100SU
The AirTAC MBLC32X100SU is a double-acting aluminum mini cylinder engineered for compact setups requiring precise end-of-stroke control. It delivers 402 N push and 346 N pull force at 0.5 MPa, making a 100 mm stroke ideal for mid-range positioning tasks. Unlike the base MBL, this version features a screw-adjustable pneumatic cushion at both ends. You tune the needle to smoothly decelerate the piston, protecting the end covers from impact on faster moves. The cushion only decelerates near the ends; it is not a load lock.
The U suffix denotes a rigid flat-end back cover, while the S indicates a built-in magnet for CMSG, DMSG, or EMSG sensor switches. The riveted rolling-packed aluminum barrel keeps the body light and tight for machine integration, while the heterogeneous two-way grease-retaining piston seal maintains lubrication over high-frequency cycles. A 20 um hard-chrome plating on the carbon-steel rod provides wear resistance.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X100SU Is Used
PCB Depaneling Saw
Feeds a circular saw blade across 100 mm to singulate populated PCB arrays, relying on the 402 N force and tunable cushion to prevent jarring stops that could stress fragile solder joints.
Carton Erector Flap
Folds minor flap panels on a compact packaging line, where the 346 N pull force retracts the arm cleanly and the adjustable cushion softens the return impact to protect the mechanical linkage.
Connector Insertion Jig
Pushes a multi-pin header into a housing over a 100 mm travel, using the DMSG sensor to verify insertion depth and the air cushion to avoid crushing the plastic housing at stroke end.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X100SU the Right Cylinder?
If you need less force, step down to the 25 mm bore (245 N push at 0.5 MPa); if your load is heavier, step up to the 40 mm bore (628 N push at 0.5 MPa). Choose this MBLC over the fixed-bumper MBL when cycle speeds are high enough that a rubber bumper cannot absorb the impact. To replace this unit, match the 32 mm bore, 100 mm stroke, G1/8 port, PT thread, U flat-end back cover, and the S magnet. Note that a plain double-acting cylinder does not hold position if air pressure drops; use an external rod lock for fail-safe holding.
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 MBLC32X100SU FAQ
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. It uses a G1/8 port and an M10x1.25 rod-end thread.
A screw needle at both ends traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. You tune the needle to match your load and speed, reducing impact noise and wear. It is a deceleration device, not a brake or load lock.
