The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X100-50 is a genuine double-acting aluminum-barrel mini cylinder with a Ø40mm bore, a 100mm nominal stroke and a rear adjustable-stroke stopper — trim up to 50mm for a usable window of 50–100mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ40X100-50 is a compact double-acting aluminum mini cylinder featuring a single Ø16 mm carbon-steel rod with 20 µm hard-chrome plating. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, making it well-suited for medium-duty handling tasks requiring a 100 mm travel distance. The riveted rolling-packed barrel and heterogeneous two-way grease-retaining piston seal ensure durable, low-friction operation in tight machine spaces.
This SKU integrates a rear stroke adjuster allowing you to trim up to 50 mm of travel, creating a usable end-position window of 50 to 100 mm. It also features an adjustable air cushion at both ends, letting you screw-tune the end-of-stroke deceleration to absorb kinetic energy from heavier loads, which protects the end covers better than a fixed rubber bumper. Note that this specific model lacks a built-in magnet, meaning it cannot accept CMSG, DMSG, or EMSG position sensors.

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.

Drives the loom beater mechanism to lay weft yarns precisely, using the 628 N push force and tunable air cushion to absorb the high-impact kinetic energy at the 100 mm stroke end without damaging end covers.
Applies torque to spin plastic screw caps onto beverage containers, utilizing the 50-100 mm adjustable stroke window to accommodate varying bottle neck heights on the same filling lane.
Feeds printed circuit boards into a depaneling router, relying on the 528 N pull force to retract the fixture quickly while dialing in the rear stopper for exact edge alignment.
If your application demands less force, stepping down to the 32 mm bore yields 402 N of push at 0.5 MPa, whereas stepping up to the 50 mm bore provides 981 N for heavier payloads. Choose this MBLCJ variant over the MBLJ when your moving mass requires tunable pneumatic cushioning rather than a fixed bumper, or over the MBLC when you need to fine-tune the rear travel end-point within that 50-100 mm window. Remember that the rear adjuster acts only as a travel stop and the cushion only decelerates; neither will mechanically hold a load in place without live air pressure.
Mounting is limited to Basic, FA flange, or LB foot styles, as this series omits back-cover or SDB pivot options. The overall length grows by the 50 mm adjustment dimension plus the 100 mm stroke, so verify your envelope dimensions. For a direct replacement, match the 40 mm bore, 100 mm stroke, 50 mm adjust code, G1/4 port, PT thread, and confirm no magnet is required. Because the rod is only 16 mm in diameter, long strokes over 300 mm require an external guide to prevent rod bending under side-load.
Quick checklist
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force reaches 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa, with a safe operating pressure range of 0.15 to 1.0 MPa.
No, this specific SKU lacks the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG position switches. The rear adjustment lets you trim up to 50 mm of travel, creating a usable stroke window of 50 to 100 mm. This adjuster is a mechanical travel stop, not a lock, and the adjustable air cushion only manages end-of-stroke deceleration.
