About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X450-40
The AirTAC MBLCJ50X450-40 is a compact double-acting mini cylinder featuring a single rod and a riveted aluminum barrel. It integrates a rear adjustable stroke stopper providing a 410-450 mm usable travel window, alongside an adjustable air cushion at both ends. Delivering 981 N push and 881 N pull at 0.5 MPa, it suits heavy end-positioning tasks. The tunable cushioning decelerates fast moving loads to protect the end covers, a distinct upgrade over the fixed bumper found on the MBLJ series.
This specific SKU uses a G1/4 port, a Ø16 hard-chrome plated carbon steel rod, and an M14x1.5 rod-end thread. Because this model lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor. The rear stopper sets the travel end but does not lock the load in place, while the cushion only manages deceleration. Overall length extends to A + 2 x stroke + adjust, meaning long strokes require external guides 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.
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 MBLCJ50X450-40 Is Used
Injection Mold Ejection
Provides 981 N of push force at 0.5 MPa to eject heavy plastic parts, using the 40 mm stroke trim to perfectly time the knockout plate position.
Pallet Conveyor Diverter
Uses the tunable air cushion to smoothly decelerate a 450 mm stroke when pushing loaded pallets, preventing harsh impacts that damage the end covers.
Woodworking Press
Applies 881 N of pull force to hold a clamping jig, relying on the riveted aluminum body for compact rigidity in tight machine spaces.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X450-40 the Right Cylinder?
For lower force needs, step down to the 40 mm bore (628 N push @0.5 MPa); for heavier pushes, step up to the 63 mm bore (1558 N push @0.5 MPa). Choose this MBLCJ over the MBLJ when your application requires screw-tunable end-of-stroke deceleration rather than a fixed rubber bumper, or over the MBLC when you need to trim the end position. The rear stroke adjuster and the air cushion are not brakes; they will not hold a load without continuous air pressure. Mounting is limited to Basic, FA, or LB; there is no SDB or back-cover option. Replacement match: 50 mm bore, 450 mm stroke, 40 mm adjust, G1/4 port, PT thread, no magnet.
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 MBLCJ50X450-40 FAQ
At 0.5 MPa it provides 981 N push and 881 N pull. At 0.7 MPa the push increases to 1374 N. The theoretical maximum is 200 kgf at 1.0 MPa.
No. Because this specific SKU lacks the -S code for a built-in magnet, it cannot accept AirTAC CMSG, DMSG, or EMSG sensors. You would need the MBLCJ50X450-40S variant for position detection.
