About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X200SCA
The AirTAC MBLC20X200SCA is a compact double-acting aluminum mini cylinder delivering 157 N push and 132 N pull force at 0.5 MPa. It features a CA pivot/clevis back cover that swings on a pin to accommodate arcing loads, making it well-suited for articulated mechanisms needing a 200 mm stroke. A built-in magnet (-S) enables position detection with CMSG reed or DMSG and EMSG electronic sensor switches.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant uses a screw-adjustable pneumatic air cushion at both ends to smoothly decelerate the piston near stroke extremes. You tune the needle to match the load and speed, cutting end-cover impact and vibration on faster moves. The riveted rolling-packed aluminum barrel keeps the body light and compact for tight spaces, while the heterogeneous two-way grease-retaining piston seal ensures lasting lubrication around the Ø8 mm hard-chrome carbon-steel rod.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X200SCA Is Used
Textile Loom Guide Arm
Swings a thread-guide arm through a 200 mm arc using the CA pivot, relying on the cushion to soften the stroke ends and the -S magnet to trigger loom timing.
Packaging Flap Folder
Folds cardboard flaps at speed where 157 N of push force is sufficient, using the tunable air cushion to prevent slamming the carton at the end of the move.
PCB Shuttle Diverter
Pushes a lightweight shuttle along a 200 mm track in a PCB handling line, using the DMSG sensor to confirm retraction before the next board enters.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X200SCA the Right Cylinder?
For lower force needs, stepping down to the 20 mm bore is already the smallest available size; stepping up to the 25 mm bore increases your push force to 245 N at 0.5 MPa. Choose this MBLC over the base MBL when your application runs at higher speeds or cycles frequently and the fixed bumper is insufficient to absorb the kinetic energy. The adjustable cushion decelerates the rod near the ends but does not lock it—this cylinder will drift if air is lost or the valve centers, so add an external rod lock for position holding.
To replace this SKU, match the 20 mm bore, 200 mm stroke, G1/8 port, PT thread, CA pivot back cover, and the -S magnet. Because the 200 mm stroke is relatively long for an Ø8 mm rod, side-load tolerance is low; use a CA or SDB pivot mounting to prevent rod bending, or guide the load externally, or switch to an MBLD double-rod cylinder for rigid support.
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 MBLC20X200SCA FAQ
At 0.5 MPa it provides 157 N push and 132 N pull. At 0.7 MPa it provides 220 N push and 185 N pull. The maximum theoretical force is 32 kgf at 1.0 MPa.
A screw-tunable needle valve at both ends traps a pocket of air to decelerate the piston smoothly before the stroke end, reducing impact and noise on fast moves. It only dampens motion; it is not a lock and will not hold the load if air pressure is lost.
