About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X350U
The AirTAC MBLC25X350U is a compact double-acting aluminum mini cylinder engineered for a 350 mm stroke, delivering 245 N of push force and 206 N of pull force at 0.5 MPa. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot support a CMSG, DMSG, or EMSG position sensor. It features a G1/8 port, a Ø10 mm carbon-steel rod with 20 µm hard-chrome plating, and a U flat-end back cover for rigid rear mounting.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needle lets you smoothly decelerate the piston near each stroke end, effectively reducing end-cover impact, noise, and vibration on faster or heavier moves. The riveted rolling-packed aluminum barrel keeps the body light and compact for tight spaces, while the heterogeneous two-way grease-retaining piston seal ensures lasting operational friction control.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X350U Is Used
Carton Flap Folding
Drives a 350 mm arm to fold corrugated cardboard flaps on packaging lines, using the adjustable air cushion to softly decelerate the 245 N push force and prevent tearing the board.
PCB Shuttle Transfer
Moves delicate printed circuit boards between testing stations, relying on the tunable end-of-stroke cushioning to prevent sudden jolts that could dislodge small components.
Tray Indexing Gate
Actuates a 350 mm sliding gate for parts tray routing, where the compact riveted aluminum barrel fits neatly into tight conveyor framework without adding excess weight.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X350U the Right Cylinder?
Select this 25 mm bore when an application requires a moderate 245 N push at 0.5 MPa over a long 350 mm travel. If you need less force, step down to the 20 mm bore (157 N push); if you need more power, step up to the 32 mm bore (402 N push). Choose this MBLC over the standard MBL when your cycle speeds are high enough that a fixed rubber bumper cannot adequately absorb the kinetic energy. For exact replacements, match the 25 mm bore, 350 mm stroke, G1/8 port, PT thread, U flat-end back cover, and no-magnet configuration.
At 350 mm, the stroke length is significant relative to the 25 mm bore and Ø10 mm rod, resulting in low side-load tolerance. To prevent rod bending and premature seal wear, use an external guide rail, select a CA or SDB pivot mounting to accommodate arcing loads, or switch to an MBLD double-rod cylinder. Note that the adjustable air cushion only decelerates the piston near the end of travel; 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 MBLC25X350U FAQ
The 25 mm bore with a Ø10 mm rod provides 245 N push and 206 N pull at 0.5 MPa, 343 N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa. It uses a G1/8 port and an M10x1.25 rod-end thread.
No, this specific SKU lacks the -S suffix, meaning it is manufactured without a built-in magnet. To use AirTAC CMSG, DMSG, or EMSG electronic or reed sensor switches, you must select an MBLC25X350S variant instead.
