About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X200SCA
The AirTAC MBLC25X200SCA is a double-acting aluminum mini cylinder with a 25 mm bore and 200 mm stroke. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. A built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic sensor switches to track rod position. The CA pivot back cover swings on a pin, accommodating arcing angular loads better than a rigid flat-end mount.
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 tune the needle to smoothly decelerate the piston near each stroke end, cutting impact shock and noise on faster moves. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, while the 20 µm hard-chrome plating on the carbon-steel rod resists wear.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X200SCA Is Used
Textile Loom Reeding
Drives a reed mechanism on a weaving loom, using the CA pivot to absorb angular rod stress while the air cushion quietly stops the 200 mm stroke on high-frequency cycle runs.
Bottle Diverter Gate
Actuates a routing flap on a packaging conveyor, where the 245 N push force easily redirects light cartons and the cushion prevents end-cover impact at 800 mm/s.
PCB Edge Tester
Positions a testing probe array over circuit boards, relying on the -S magnet and DMSG electronic switch to confirm the 200 mm extend position before measurement begins.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X200SCA the Right Cylinder?
At 0.5 MPa, this 25 mm bore yields 245 N push and 206 N pull. If your application requires less force, step down to the 20 mm bore (157 N push / 132 N pull). If you need higher thrust, step up to the 32 mm bore (402 N push / 346 N pull). Choose this MBLC over the fixed-bumper MBL when cycling speeds are high or the moved mass is heavy enough that a rubber bumper would wear out too quickly.
With a 200 mm stroke, the 10 mm rod has limited tolerance for side loads and risks bending under off-center forces. Use an external guide rail, leverage the CA clevis pivot, or switch to an MBLD double-rod cylinder to prevent rod deflection. The PT port is tapered, the rod-end thread is M10x1.25, and the cushion decelerates but does not lock position when air is removed.
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 MBLC25X200SCA FAQ
At 0.5 MPa, the 25 mm bore provides 245 N of push force and 206 N of pull force. At 0.7 MPa, push increases to 343 N. The theoretical maximum is 50 kgf at 1.0 MPa. It uses a G1/8 port with PT (tapered) threading, a 10 mm rod, and an M10x1.25 rod-end thread.
A screw-tunable needle at both ends traps a pocket of exhaust air to decelerate the piston smoothly near the stroke limits. You adjust it to match your load and speed, which reduces end-cover impact, vibration, and noise compared to a fixed rubber bumper. It only decelerates near the ends and does not lock the load when air is removed.
