About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X225U
The AirTAC MBLC25X225U is a double-acting aluminum mini cylinder with a 25 mm bore and 225 mm stroke. It generates 245 N push and 206 N pull force at 0.5 MPa. Unlike the base MBL, this variant uses a screw-adjustable pneumatic cushion at both stroke ends. You tune the needle to decelerate the piston smoothly, cutting end-cover impact and vibration on faster moves. The U suffix denotes a rigid flat-end back cover for straightforward inline mounting.
This actuator features a riveted rolling-packed aluminum barrel for a compact, lightweight body that fits tight machine spaces. It relies on a heterogeneous two-way grease-retaining piston seal and a 20 µm hard-chrome plated carbon-steel rod. Because this specific SKU lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X225U Is Used
PCB Depaneling Router
Drives the Z-axis cutting spindle on an electronics depaneling machine, using the 245 N force and tuned end-cushions to stop the 225 mm travel smoothly without jarring the fragile board.
Carton Flap Folder
Folds minor carton flaps on a packaging conveyor where the 206 N pull retracts the arm reliably, while the adjustable air cushion prevents harsh snapping at the end of the stroke.
IC Test Handler Gate
Actuates a sorting gate in semiconductor test handlers, moving small masses rapidly with the 225 mm stroke while the compact riveted barrel fits inside the dense machinery frame.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X225U the Right Cylinder?
The 25 mm bore provides 245 N push at 0.5 MPa. If your load is lighter, step down to the 20 mm bore for 157 N; if you need more force, step up to the 32 mm bore for 402 N. Choose this MBLC over the base MBL when your cycle speeds or moving masses outgrow a fixed rubber bumper. The adjustable cushion only decelerates the piston near the ends and does not lock the load; a plain cylinder drifts when air is lost, so add an external rod lock for position holding.
For a 225 mm stroke, the 10 mm rod has limited tolerance for side loads. Prevent rod bending by guiding the load externally, using a pivot bracket, or switching to an MBLD double-rod cylinder. Replacement match: 25 mm bore, 225 mm stroke, G1/8 port, M10x1.25 rod thread, PT thread form, U flat-end cover, no magnet.
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 MBLC25X225U FAQ
At 0.5 MPa, it provides 245 N push and 206 N pull. At 0.7 MPa, it provides 343 N push and 289 N pull. The maximum theoretical force is 50 kgf at 1.0 MPa.
No. This specific SKU lacks the -S suffix, meaning it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. You must select an MBLC25X225SU model if position detection is required.
