About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X400-100
The AirTAC MBLCJ50X400-100 is a compact double-acting aluminum mini cylinder featuring a rear adjustable stroke stopper and an adjustable air cushion at both ends. It delivers 981 N of push force and 881 N of pull force at 0.5 MPa. The 100 mm rear adjuster yields a usable travel window of 300 to 400 mm, allowing precise mechanical tuning of the end position without relying on sensors. A G1/4 port feeds the Ø16 hard-chrome plated carbon-steel rod.
Twin screw-tunable air cushions decelerate heavy loads near each end cap, preventing impact damage that a fixed rubber bumper cannot absorb. Because this 400 mm stroke pushes a small 16 mm rod far from the front cover, external guide rails are strongly recommended to prevent rod bending under side loads. Note that this specific SKU lacks a built-in magnet, so it cannot host CMSG, DMSG, or EMSG electronic position switches.

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.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a margin.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X400-100 Is Used
Thermoforming Press
Drives the mold closure on a small thermoforming press, using the 981 N push force and tunable cushion to decelerate the 400 mm travel before locking the tool.
Pallet Divert
Actuates a routing gate on a pallet conveyor, trimming the rear stroke 100 mm to hit a specific divert position without reprogramming the PLC.
Stamping Feed
Pushes a metal strip into a progressive stamping die, relying on the adjustable air cushion to protect the end cover from the heavy 50 mm piston mass.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X400-100 the Right Cylinder?
When sizing this 50 mm bore, step down to the 40 mm version if your load requires less energy—40 mm yields 628 N push at 0.5 MPa—or step up to the 63 mm bore for 1558 N push if heavier pressing is needed. Choose the MBLCJ over the MBLJ when your cycle speed demands active deceleration rather than a fixed bumper, or choose the MBLC if your travel is fixed and you do not need the 300-400 mm rear trim window.
Remember that the rear stroke adjuster is a mechanical travel stop, not a load-holding lock; the rod will drift if air is removed. Mounting is limited to Basic, FA flange, or LB foot styles—SDB pivot or back-cover options are not available. To replace this unit exactly, match the 50 mm bore, 400 mm stroke, 100 mm adjust code, G1/4 PT thread, and confirm no magnet is fitted.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Adjustable window fits your end position
- ✓ Adjuster is a travel stop, not a lock
- ✓ Magnet (S) for sensors?
- ✓ Side load — add a guide on long strokes
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear stopper for the end position (a travel stop, not a lock).
- check Avoid side load; add an external guide on long strokes.
- check Mounting: Basic / FA flange / LB foot (no SDB, no back-cover code).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X400-100 FAQ
At 0.5 MPa, push force is 981 N and pull force is 881 N. At 0.7 MPa, push force reaches 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
This SKU lacks a built-in magnet, so it cannot accept CMSG reed or DMSG/EMSG solid-state sensors. The rear 100 mm adjuster is a travel stop that sets the end position; it does not hold the load, and the air cushion only decelerates motion.
