The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X150-40 is a genuine double-acting aluminum-barrel mini cylinder with a Ø50mm bore, a 150mm nominal stroke and a rear adjustable-stroke stopper — trim up to 40mm for a usable window of 110–150mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ50X150-40 is a compact double-acting mini cylinder featuring a 50mm bore and a 150mm stroke. It delivers 981 N of push force at 0.5 MPa, making it well-suited for heavier pressing and lifting tasks. The rear stroke adjuster allows you to trim up to 40mm of travel, creating a usable end-position window of 110-150mm. Tunable air cushions at both ends absorb kinetic energy to prevent end-cover damage during high-speed moves. This SKU uses a PT tapered port thread and lacks a built-in magnet, meaning it cannot support a position sensor without modification.
Constructed with a riveted aluminum barrel and a 20um hard-chrome plated carbon-steel rod, it resists wear and retains grease via a two-way piston seal. The rear stopper sets the travel end-point but does not mechanically hold the load; external guides are recommended to manage side-load forces on the 16mm rod. Mounting is limited to Basic, FA, or LB styles, as no back-cover or SDB pivot options exist for this series.

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.

Provides the 981 N push force needed to separate empty pallets in a packaging line, using the 40mm stroke adjustment to fine-tune the ejection distance.
Lifts loaded crates at high cycle rates; the adjustable air cushion decelerates the 150mm stroke to prevent hydraulic-like impact on the end covers.
Positions heavy MDF panels on a conveyor, using the 110-150mm usable window to accommodate varying panel widths without changing the cylinder.
If 981 N of thrust is excessive for your application, stepping down to the 40mm bore yields 628 N of push force at 0.5 MPa, offering a lighter footprint. Conversely, if you need greater power, the 63mm bore provides 1558 N. Choose the MBLCJ over the MBLJ when your moving mass threatens to damage the end covers, as the MBLJ relies solely on a fixed rubber bumper. Remember that neither the rear travel stopper nor the cushion needle acts as a lock; the rod will drift if air is removed, so use an external locking device for fail-safe holding.
For exact replacement, match the 50mm bore, 150mm stroke, 40mm adjust code, G1/4 port size, PT thread form, and Basic mounting style. Because this SKU lacks the -S magnet suffix, it cannot accept AirTAC CMSG, DMSG, or EMSG sensors. If position feedback is required, select an MBLCJ50X150-40S variant instead.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push force increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
No, the rear 40mm adjuster is strictly a travel stop that sets the end position within a 110-150mm window; it does not lock the load. Similarly, the adjustable air cushion only decelerates the piston near the stroke ends. An external locking mechanism is required for position holding.
