The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X100-100S is a genuine double-acting aluminum-barrel mini cylinder with a Ø20mm bore, a 100mm nominal stroke and a rear adjustable-stroke stopper — trim up to 100mm for a usable window of 0–100mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ20X100-100S is a compact double-acting mini cylinder featuring a 20mm bore and a 100mm stroke. A rear adjuster allows trimming up to 100mm of travel, yielding a usable 0-100mm end-position window. It generates 157N of push force at 0.5MPa and integrates an adjustable air cushion at both ends to tune deceleration. The -S code denotes a built-in magnet for CMSG, DMSG, or EMSG sensor switches.
Distinguish the rear travel stopper from the cushion: the stopper sets the end position, while the cushion screws regulate end-of-stroke speed to protect the end covers. The riveted aluminum barrel and 20um hard-chrome plated Ø8 carbon-steel rod withstand rapid 30-800mm/s cycles. Note the overall length equals A plus 200mm plus the 100mm adjuster, requiring careful spatial planning in tight assemblies.

The rear stopper sets the end position — it is a travel stop, not a lock. Overall length = A + 2 × stroke + adjustable stroke. MBLJ/MBLCJ mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.

Actual usable force is lower than theoretical due to friction and back-pressure. Size with a margin.

Uses the 0-100mm adjustable window to precisely set component insertion depth on a pick-and-place head, relying on the 157N force and air cushion for soft landing.
Tunes the exact retract distance for an adhesive dispenser nozzle, while the cushion valve halts the 100mm stroke smoothly to prevent fluid tailing.
Pushes stamped micro-parts from a die set; the DMSG electronic sensor tracks the 8mm rod position for high-speed ejection timing.
At 157N push (0.5MPa), this 20mm bore suits light loads; step down if moving just a micro-actuator, or step up to the 25mm bore (245N push) for heavier resistance. Choose this MBLCJ over the MBLJ when movable end-covers are needed to absorb kinetic energy instead of relying on a fixed rubber bumper. The rear stopper and cushion valve decelerate the load but do not lock position—rod drift occurs without live air, so use an external locking mechanism for true holding. Mounting is limited to Basic, FA, or LB (no SDB or back-cover), and the G1/8 port uses a default PT thread form.
Quick checklist
At 0.5MPa, the 20mm bore provides 157N push and 132N pull. At 0.7MPa, push increases to 220N. The maximum theoretical force is 32kgf at 1.0MPa.
The 100mm rear adjuster acts as a travel stop to set your exact 0-100mm end position, while the adjustable air cushion uses screw valves to regulate deceleration speed near the covers. Neither holds the load without air pressure.
