The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X500-75 is a genuine double-acting aluminum-barrel mini cylinder with a Ø32mm bore, a 500mm nominal stroke and a rear adjustable-stroke stopper — trim up to 75mm for a usable window of 425–500mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ32X500-75 is a compact double-acting aluminum mini cylinder engineered for exacting long-travel tasks. It features a rear stroke adjuster allowing a 75mm trim, creating a usable end-position window of 425 to 500mm. A screw-tunable adjustable air cushion at both ends manages deceleration for heavy moving masses, actively protecting the end covers from impact damage. Delivering 402N of push force at 0.5MPa, it suits extended reach operations in confined machine footprints.
This model uses a Ø12mm carbon-steel rod with 20μm hard-chrome plating to resist scuffing, paired with a heterogeneous two-way grease-retaining piston seal inside a riveted rolling-packed aluminum barrel. Because this SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor. The rear stopper sets the travel end but does not lock the load; external guide mechanisms are mandatory for a 500mm stroke to prevent rod bending and premature seal wear.

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.

Pushes populated PCB panels along a 500mm conveyor transfer station, using the 425-500mm adjustable window to dial in the exact push-distance without moving mechanical hard stops.
Actuates a fabric guide or tensioner arm across a 500mm span, relying on the tunable air cushion to gently decelerate the 402N thrust and prevent yarn snagging at stroke end.
Advances a copper foil strip roll feed over a 425-500mm cycle, where the 75mm rear adjuster compensates for varying material roll diameters and the riveted barrel handles the cleanroom environment.
When sizing this 32mm bore, stepping down to the 25mm version drops the push force to 245N at 0.5MPa, while stepping up to the 40mm bore increases it to 628N. Choose the MBLCJ over the MBLJ when your moving load exceeds what a fixed rubber bumper can absorb, as the screw-tunable air cushion actively bleeds off kinetic energy. Compared to the MBLC, this MBLCJ adds the 75mm rear stroke adjuster for fine-tuning the end position.
The rear adjuster is a travel stop, not a lock; the cushion only decelerates, so a separate external guide or locking device is required to hold position without live air. Mounting is restricted to Basic, FA flange, or LB foot brackets (no SDB pivot or back-cover option exists). For exact replacement, match the 32mm bore, 500mm stroke, 75mm adjust code, G1/8 port, PT thread, and confirm no magnet is fitted. At 500mm, the unsupported rod is highly susceptible to side-load bending.
Quick checklist
At 0.5MPa, it provides 402N of push force and 346N of pull force. At 0.7MPa, the push force increases to 563N. The absolute maximum theoretical force is 82kgf at 1.0MPa.
The 75mm adjustable stroke is a rear mechanical stopper that physically limits rod travel, creating a usable 425-500mm end-position window. The adjustable air cushion is a separate screw-tunable valve that controls exhaust flow to decelerate the piston near the end covers. Neither holds the load; the cushion only slows movement.
