The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X400-100S is a genuine double-acting aluminum-barrel mini cylinder with a Ø50mm bore, a 400mm nominal stroke and a rear adjustable-stroke stopper — trim up to 100mm for a usable window of 300–400mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ50X400-100S is a compact double-acting aluminum mini cylinder featuring a rear adjustable stroke and a tunable air cushion at both ends. It delivers 981 N of push force at 0.5 MPa. The rear stopper allows you to trim up to 100 mm of travel, creating a precise 300-400 mm usable stroke window. A built-in magnet (-S) enables position detection with CMSG reed or DMSG and EMSG electronic switches.
Unlike the base MBLJ with its fixed rubber bumper, this model uses screw-tunable deceleration to protect the end covers during heavy, fast moves. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod withstand demanding cycles. The rear adjuster sets the travel end but does not lock the load; external guides are recommended for this 400 mm stroke to prevent rod bending.

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 981 N push force to separate and feed heavy wooden pallets on a packaging line, relying on the 300-400 mm adjustable window to match varying pallet widths.
Drives a heavy fabric calendar roll where the 400 mm stroke and tunable air cushion absorb the massive end-of-stroke kinetic energy without slamming the covers.
Lifts filled beverage crates, using the built-in magnet for DMSG electronic position feedback and the rear stopper to fine-tune the exact stacking height.
Delivering 981 N push at 0.5 MPa, this 50 mm bore suits heavy fixtures. If you need less force, step down to the 40 mm bore (628 N push); if you need more, step up to the 63 mm bore (1558 N push). Choose this MBLCJ over the MBLJ when your application speed requires tunable end-of-stroke cushioning rather than a fixed bumper, or over the MBLC when you need that rear travel adjustment.
The 100 mm rear adjuster is a travel stop, not a lock; the cushion only decelerates, so neither holds position without live air. Mounting is limited to Basic, FA, or LB (no SDB or back-cover options). For an exact replacement, match the 50 mm bore, 400 mm stroke, 100 mm adjust code, G1/4 port, PT thread, and the -S magnet.
Quick checklist
At 0.5 MPa it provides 981 N push and 881 N pull. At 0.7 MPa it provides 1374 N push. The maximum theoretical force is 200 kgf at 1.0 MPa.
The 100 mm rear adjuster is a mechanical travel stop that sets your end position within the 300-400 mm window; it does not lock the load. The adjustable air cushion is a screw-tunable valve that controls end-of-stroke deceleration to protect the cylinder, but it also does not hold the load.
