The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X400-10 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 10mm for a usable window of 390–400mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ50X400-10 is a compact double-acting aluminum mini cylinder featuring a rear travel adjuster and tunable air cushions at both ends. It delivers 981 N of push force and 881 N of pull force at 0.5 MPa. The rear stopper allows you to trim up to 10 mm of travel, creating a precise 390-400 mm usable stroke window for a 400 mm nominal length. This specific SKU uses a PT tapered port thread and lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors.
Designed for demanding cycles, the adjustable air cushioning lets you screw-tune the end-of-stroke deceleration to absorb heavy kinetic energy, protecting the end covers where a fixed rubber bumper would fail. The Ø16 hard-chrome plated carbon steel rod and riveted rolling-packed barrel provide durable, leak-free service. Because the 400 mm stroke is quite long for a mini body, an external guide rail is highly recommended to prevent rod bending and seal wear under side loads. The rear adjuster functions strictly as a mechanical stop to set the end position; it does not lock or hold the load in place.

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 eject heavy plastic parts from a mold, using the 10 mm rear stroke adjustment to dial in the exact 390 mm ejection depth without reprogramming the PLC.
Pushes loaded pallets across a transfer line with a 400 mm travel, relying on the adjustable air cushions to smoothly decelerate the heavy 50 mm bore thrust before it strikes the end cover.
Actuates a deep-draw forming tool over a 390-400 mm usable window, where the riveted aluminum barrel and Ø16 hard-chrome rod withstand the repetitive high-impact cycles.
Choose this 50 mm bore when you need substantial thrust—981 N push at 0.5 MPa—for a long 400 mm travel application that requires fine-tuned deceleration. If your payload is lighter, stepping down to the 40 mm bore reduces the push force to 628 N while saving valuable space. Conversely, if you need even more power, stepping up to the 63 mm bore yields 1558 N of push force. For replacement, match the 50 mm bore, 400 mm stroke, 10 mm adjust code, G1/4 port, PT thread, and Basic mounting (no FA/LB/SDB codes present). Since this SKU lacks the -S suffix, it has no magnet and cannot accept a sensor switch.
Compare this model to the MBLJ if you only need a fixed bumper for light loads, or the MBLC if you require fixed end positions with cushioning. Remember that the adjustable stroke mechanism and the air cushions only manage travel limits and deceleration; neither will hold a load stationary without continuous air pressure. For a 400 mm stroke, always pair the cylinder with an external linear guide to handle side loads and prevent rod deflection.
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, with a maximum theoretical output of 200 kgf at 1.0 MPa. The rear adjuster allows you to trim up to 10 mm of travel, giving you a usable stroke window of 390 to 400 mm.
Because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot accept AirTAC CMSG, DMSG, or EMSG sensor switches. Additionally, the adjustable air cushion only regulates end-of-stroke deceleration to protect the end covers, and the rear stroke adjuster acts as a travel stop; neither feature locks or holds the load in place without live air pressure.
