About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X250U
The AirTAC MBLC25X250U is a double-acting aluminum mini cylinder engineered for a 25 mm bore and 250 mm stroke. It generates 245 N of push force and 206 N of pull force at 0.5 MPa. A defining feature is the screw-adjustable pneumatic cushion at both ends, which decelerates the piston smoothly near stroke limits to absorb shock on fast moves. The U suffix denotes a rigid flat-end back cover, and the absence of an S code means this specific SKU lacks a built-in magnet for position sensing.
This actuator uses a riveted rolling-packed aluminum barrel for a compact, lightweight body that slides into tight machine envelopes. The Ø10 mm carbon-steel rod features a 20 µm hard-chrome plating to resist wear, paired with a heterogeneous two-way grease-retaining piston seal that maintains lubrication over high cycle counts. Because the 250 mm stroke amplifies leverage on the small rod, external guiding is strongly recommended to prevent premature seal wear and rod bending.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X250U Is Used
Packaging Lane Diverter
Routes cartons between labeling stations. The 245 N push force easily shunts boxes, while the adjustable air cushion halts the 250 mm stroke smoothly to prevent slamming the diverter arm into the end cover at high throughput.
Textile Yarn Guide
Traverses yarn guides across a weaving beam. The compact riveted barrel fits narrow loom frames, and the tunable cushion decelerates the 250 mm traverse to protect delicate filaments from snapping during rapid direction changes.
Small Parts Ejector
Pushes stamped metal parts out of a die press. The 206 N pull force retracts the rod clear of the tooling, and the U flat-end back cover mounts rigidly to the press frame to withstand repeated high-frequency ejection cycles.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X250U the Right Cylinder?
At 0.5 MPa, this 25 mm bore yields 245 N push and 206 N pull. If your payload is lighter, stepping down to the 20 mm bore reduces the force to 157 N push and saves space. For heavier masses, the 32 mm bore increases output to 402 N push and 346 N pull. Choose this MBLC variant over the base MBL when your cycle speed or payload mass outstrips what a fixed rubber bumper can safely absorb. The cushion needle tunes end-of-stroke deceleration but does not lock the rod; if you must hold position without live air, install an external rod lock or pilot-operated check valve.
For replacement matching, confirm the 25 mm bore, 250 mm stroke, G1/8 port, M10x1.25 rod-end thread, PT port thread form, U flat-end back cover, and no magnet. Given the 250 mm stroke on a Ø10 mm rod, side-load tolerance is low; manage rod bending by using an external guide rail, switching to an SDB pivot bracket, or selecting an MBLD double-rod cylinder.
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 MBLC25X250U FAQ
At 0.5 MPa, it provides 245 N push and 206 N pull. At 0.7 MPa, it delivers 343 N push and 289 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa with a speed range of 30-800 mm/s.
No. Because this SKU lacks the -S code, it has no built-in magnet and cannot host a CMSG, DMSG, or EMSG sensor switch. To use reed or electronic solid-state position detection, you must select the MBLC25X250SU variant instead.
