About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X25SCA
The AirTAC MBLC25X25SCA is a compact double-acting aluminum mini cylinder engineered for tight-assembly automated motion. It delivers 245 N push and 206 N pull at 0.5 MPa, making this 25 mm bore, 25 mm stroke unit ideal for short, rapid linear transfers. The riveted rolling-packed aluminum barrel keeps the body light and spatially efficient, while the 20 um hard-chrome plating on the carbon-steel rod provides reliable wear resistance.
This configuration includes a CA pivot/clevis back cover that swings on a pin to accommodate arcing or angular loads, preventing binding during traversal. It features a built-in magnet (-S) for position detection via AirTAC CMSG, DMSG, or EMSG sensor switches. Unlike the base MBL, this MBLC variant uses a screw-adjustable pneumatic air cushion at both ends to smoothly decelerate the piston near stroke limits, absorbing impact on fast cycles without acting as a load lock.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X25SCA Is Used
PCB Pick-and-Place Pivot
Uses the CA clevis to swing a 245 N pick-and-place arm for electronic board population, relying on the cushion to halt the 25 mm stroke softly without jarring delicate components.
Pharmaceutical Vial Sorting
Actuates a 25 mm diverter gate on a high-speed packaging line, where the tunable end-of-stroke deceleration prevents glass-to-glass contact vibration.
Small-Part Lane Chute
Pivots a reject chute for misaligned plastic fasteners, utilizing the compact riveted body to fit within a 32 mm frame width constraint.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X25SCA the Right Cylinder?
For lower force requirements, step down to the 20 mm bore (157 N push at 0.5 MPa); if your application needs more thrust, step up to the 32 mm bore (402 N push at 0.5 MPa). Select this MBLC over the base MBL when your cycle speed is high enough that a fixed rubber bumper cannot adequately absorb the impact. The replacement match is a 25 mm bore, 25 mm stroke, PT thread, CA back cover, with an -S magnet. Remember that the adjustable cushion only decelerates near the ends; a plain cylinder will drift and drop if air is lost or the valve centers, so fit an external rod lock for fail-safe position holding.
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 MBLC25X25SCA FAQ
This 25 mm bore cylinder uses a G1/8 port and a Ø10 mm rod with an M10x1.25 thread. It generates 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.
The -S denotes a built-in magnet for CMSG reed or DMSG/EMSG electronic sensor switches. The adjustable air cushion at both ends uses a screw needle to restrict exhaust flow, decelerating the piston smoothly near the 25 mm stroke ends to reduce impact; it is a damping device, not a locking brake.
