About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X150SCA
The AirTAC MBLC25X150SCA is a double-acting aluminum mini cylinder with a 25mm bore and 150mm stroke. It generates 245N of push force and 206N of pull force at 0.5MPa. A built-in magnet (-S) enables position detection using CMSG reed or DMSG and EMSG electronic sensor switches. The CA back cover provides a pivot clevis that swings on a pin, accommodating arcing or angular loads.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. You can tune the exhaust needle to smoothly decelerate the piston near stroke limits, cutting impact vibration and noise on faster moves. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, while the heterogeneous two-way grease-retaining piston seal ensures consistent lubrication over long cycling periods.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X150SCA Is Used
PCB Router Gantry
Drives a light routing head across circuit boards where the 245N push force at 0.5MPa is sufficient, and the cushioned 150mm stroke prevents gantry jerk at high traverse speeds.
Pouch Sealing Arm
Actuates a sealing jaw on a vertical form-fill-seal machine, using the CA pivot clevis to accommodate slight jaw misalignment while the magnet confirms jaw position via a DMSG sensor.
Carton Flap Folder
Folds minor flaps on a packaging line where the 206N pull force easily handles cardboard resistance, and the adjustable cushion softens the 150mm retract stop to protect packaging mechanics.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X150SCA the Right Cylinder?
If you need less force, stepping down to the 20mm bore yields 157N push at 0.5MPa. For heavier payloads, the 32mm bore provides 402N push. Choose this MBLC over the fixed-bumper MBL when your application runs at higher speeds or cycles frequently and needs smooth end-of-stroke deceleration. The 150mm stroke is well within the 500mm standard limit, but because the 10mm rod has low side-load tolerance, use the CA pivot clevis to absorb angular misalignment or add an external guide rail to prevent rod bending.
Replacement match: 25mm bore, 150mm stroke, G1/8 port, PT thread, CA pivot back cover, built-in magnet. Note that the air cushion only decelerates the piston near the ends; it is not a brake and will not 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 MBLC25X150SCA FAQ
At 0.5MPa, this 25mm bore cylinder provides 245N push and 206N pull force. At 0.7MPa, push increases to 343N. The maximum theoretical force is 50kgf at 1.0MPa operating pressure.
A screw-tunable needle at both ends restricts exhaust flow to decelerate the piston smoothly before the end cover. You adjust it to match your load and speed, which reduces impact shock and noise compared to the fixed rubber bumper found on the standard MBL series.
