The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X50-10S is a genuine double-acting aluminum-barrel mini cylinder with a Ø50mm bore, a 50mm nominal stroke and a rear adjustable-stroke stopper — trim up to 10mm for a usable window of 40–50mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ50X50-10S is a compact double-acting aluminum mini cylinder engineered for high-force tasks, delivering 981 N of push force at 0.5 MPa. It integrates a rear stroke adjuster allowing you to trim up to 10 mm of travel, creating a usable 40-50 mm end-position window. Unlike the base MBLJ which relies on a fixed rubber bumper, this unit features a screw-tunable adjustable air cushion at both ends to decelerate heavier loads smoothly and protect the end covers from impact wear.
This specific configuration includes a built-in magnet (-S) for use with AirTAC CMSG reed or DMSG and EMSG solid-state sensor switches to track rod position. The Ø16 mm carbon-steel rod is treated with a 20 µm hard-chrome plating to resist scoring, paired with a heterogeneous two-way grease-retaining piston seal inside the riveted rolling-packed barrel. Remember that the rear stopper sets the travel end and the cushion only decelerates; neither component acts as a mechanical lock to hold a load in place without live air pressure.

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.

Delivers 981 N of push force to cleanly shear plastic webbing on a rotary thermoforming line, using the 40-50 mm stroke window to dial in the exact cutting depth.
Applies precise downward torque on bottle capping spindles, utilizing the adjustable air cushion to prevent thread stripping during high-speed capping.
Secures wooden workpieces on a CNC router bed, relying on the -S magnet and DMSG sensor to confirm clamp engagement before the spindle starts cutting.
When sizing this 50 mm bore, stepping down to the 40 mm bore reduces your output to 628 N push at 0.5 MPa, while stepping up to the 63 mm bore increases it to 1558 N. Choose this MBLCJ over the MBLJ when your application generates high kinetic energy at the stroke ends and requires tunable cushioning rather than a fixed bumper. If your stroke length is fixed and does not need the 40-50 mm rear trim window, the MBLC variant offers the same air cushioning without the adjustment mechanism.
The rear travel adjuster is a hard stop, not a locking device, so external guides are required if the load must be held rigidly in place. Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option available. To replace this exact unit, match the 50 mm bore, 50 mm stroke, 10 mm adjust code, G1/4 port, PT thread, and the -S magnet option.
Quick checklist
At 0.5 MPa operating pressure, this 50 mm bore 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.
The 10 mm rear stroke adjustment is a mechanical travel stop that sets the end position within a 40-50 mm usable window. The adjustable air cushion is a separate screw-tunable valve that regulates exhaust flow to decelerate the piston near the end covers. Neither feature locks or holds the load without continuous air pressure.
