About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X30SU
The AirTAC MBLC25X30SU is a double-acting mini cylinder engineered for tight spaces, delivering 245 N of push force and 206 N of pull force at 0.5 MPa. It features a 25 mm bore, a 30 mm stroke, and a built-in magnet (-S) for non-contact position detection using CMSG, DMSG, or EMSG sensor switches. A U-style flat-end back cover provides a rigid rear mounting interface. The PT threaded port is G1/8.
Unlike the base MBL series with its fixed rubber bumper, this MBLC variant incorporates a screw-adjustable pneumatic air cushion at both stroke ends. Tuning the cushion needle lets you smoothly decelerate the Ø10 mm hard-chrome carbon-steel rod near the end caps, effectively reducing impact shock and vibration on faster or heavier small-part moves. The riveted rolling-packed aluminum barrel keeps the overall footprint compact and lightweight, while the heterogeneous two-way grease-retaining piston seal ensures lasting operational stability.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X30SU Is Used
PCB Component Insertion
Provides 245 N of push force to seat through-hole electronic connectors onto printed circuit boards, using the adjustable cushion to prevent hard impact at the 30 mm stroke end.
Pharmaceutical Carton Flap Folding
Drives a small folding arm on high-speed medical packaging lines, relying on the tunable air cushion to silently decelerate the 25 mm bore before the U-style back cover takes the load.
Plastic Trim Clip Fastening
Presses automotive interior clips into plastic trim panels, utilizing the built-in magnet and CMSG reed switch to confirm the 30 mm stroke is fully extended before the main press cycle.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X30SU the Right Cylinder?
Choose this 25 mm bore when an application requires roughly 245 N of push force at 0.5 MPa. If your load is lighter, stepping down to the 20 mm bore yields 157 N of push force, conserving compressed air. For heavier payloads, stepping up to the 32 mm bore provides 402 N of push force. Select the MBLC over the standard MBL when your cycle speeds exceed what a fixed rubber bumper can absorb cleanly. To replace this unit exactly, match the 25 mm bore, 30 mm stroke, G1/8 PT port, M10x1.25 rod-end thread, U flat-end back cover, and the -S built-in magnet. Note that the pneumatic cushion only decelerates the piston near the stroke ends; it does not lock or hold the rod in place 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 MBLC25X30SU FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. It uses a G1/8 PT threaded port and features an M10x1.25 rod-end thread.
The cushion is a screw-tunable pneumatic needle at both ends that traps a small amount of exhaust air to decelerate the piston smoothly before it hits the end cap, which is ideal for reducing noise and vibration on faster cycles. The -S code denotes a built-in magnet that allows external CMSG (reed), DMSG, or EMSG (electronic solid-state) sensor switches to detect the rod position without contacting the cylinder body.
