About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X175SCA
The AirTAC MBLC25X175SCA is a compact, double-acting aluminum mini cylinder featuring a tunable pneumatic air cushion at both stroke ends. Generating 245 N of push force and 206 N of pull force at 0.5 MPa, this 25 mm bore unit is built for fast, repetitive motion where fixed rubber bumpers would fail. The 175 mm stroke provides extended travel for assembly mechanisms that require smooth deceleration of heavier loads at high cycling frequencies.
This variant includes a CA pivot clevis back cover, allowing the body to swing on a pin to accommodate angular misalignment. It carries the -S code for a built-in magnet, enabling position detection via CMSG reed or DMSG and EMSG solid-state sensor switches. The riveted rolling-packed aluminum barrel keeps the envelope tight, while the Ø10 mm carbon-steel rod features 20 µm hard-chrome plating to resist scoring and extend seal life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X175SCA Is Used
Flow-Wrap Carton Sealing
Drives the pivoting sealing jaw on continuous flow-wrap packaging lines, using the CA clevis to handle arc movement while the air cushion softens 175 mm strokes at high speed.
Greenhouse Vent Actuation
Opens and closes roof vent flaps in horticulture automation, where the CA pivot absorbs structural flex and the cushioning prevents jarring impacts on aluminum framing.
Textile Loom Takedown
Actuates the fabric takedown mechanism on weaving looms, providing 245 N of push at 0.5 MPa with smooth end-of-stroke damping to protect delicate yarn tension.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X175SCA the Right Cylinder?
Stepping down to the Ø20 bore yields 157 N of push force at 0.5 MPa, which is often too light for arcing loads; stepping up to the Ø32 bore provides 402 N, offering a sturdier margin for pivoting mass. Choose this MBLC over the base MBL when cycle speeds exceed the absorption capacity of a fixed rubber bumper. The adjustable cushion needle decelerates the piston near the end caps but does not lock the rod—if air drops, the load drifts, requiring an external pilot check for holding. Replacement match: 25 mm bore, 175 mm stroke, G1/8 port, PT thread, CA back cover, built-in 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 MBLC25X175SCA FAQ
At 0.5 MPa, this 25 mm bore cylinder delivers 245 N of push force and 206 N of pull force. At 0.7 MPa, the push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps a pocket of exhaust air to decelerate the piston smoothly near the stroke limits. You dial the needle to match the load and speed, which cuts end-cover impact, noise, and vibration—unlike a non-adjustable fixed rubber bumper.
