About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X150-50
The AirTAC MBLCJ50X150-50 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a tunable air cushion at both ends. It delivers a robust 981 N of push force and 881 N of pull force at 0.5 MPa, making it well-suited for driving heavier jigs or mid-sized machine axes. The rear stopper allows you to trim up to 50 mm of travel, creating a precise usable stroke window of 100 to 150 mm for processes requiring exact end-positioning without mechanical spacers.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable end-of-stroke deceleration to absorb kinetic energy smoothly, protecting the end covers during faster cycling. The riveted rolling-packed aluminum barrel and heterogeneous two-way grease-retaining piston seal retain lubrication over a long service life, while the carbon-steel rod features 20 µm hard-chrome plating for wear resistance. This specific SKU is supplied without a built-in magnet, meaning it cannot support a CMSG, DMSG, or EMSG position sensor.

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)

| 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 MBLCJ50X150-50 Is Used
Injection Mold Ejection
Provides 981 N of push force at 0.5 MPa to positively eject heavy plastic parts from molds, using the 100-150 mm adjustable window to fine-tune the ejection distance.
Pallet Diverter Arm
Actuates a heavy diverter mechanism on a packaging conveyor line, utilizing the tunable air cushion to softly arrest the 150 mm stroke and prevent shock loads.
Press Fit Sub-assembly
Drives a 50 mm bore pressing action to insert metal bushings into aluminum housings, relying on the rear travel stopper to guarantee a precise 100 mm minimum insertion depth.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X150-50 the Right Cylinder?
When sizing this 50 mm bore cylinder, consider stepping down to the 40 mm version if your load requires less force (628 N push at 0.5 MPa), or stepping up to the 63 mm bore if you need substantially more thrust (1558 N push at 0.5 MPa). Choose the MBLCJ over the MBLJ when your moving mass requires active deceleration to prevent end-cover impact, or over the MBLC when you need both tunable cushioning and a rear travel stopper. Keep in mind the rear adjuster is strictly a travel stop, not a load-holding brake; if the application requires position holding without continuous air pressure, you must use an external locking mechanism.
Mounting is limited to Basic, FA flange, or LB foot styles, as this series does not offer a back-cover or SDB pivot option. The overall length follows the formula A + 2 x stroke + adjust, resulting in a longer body than a standard cylinder. For a direct replacement, match the 50 mm bore, 150 mm stroke, 50 mm adjust code, G1/4 port, PT thread form, and confirm no magnet (S) is required. The Ø16 mm rod handles high axial loads but requires an external guide if subjected to lateral forces.
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 MBLCJ50X150-50 FAQ
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 is 1374 N, with a theoretical maximum of 200 kgf at 1.0 MPa. It uses a G1/4 port, a Ø16 mm rod, and an M14x1.5 rod-end thread.
This specific SKU lacks the -S code, so it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG electronic position sensors. Additionally, the 50 mm rear adjuster is a travel stop that sets the stroke window from 100 to 150 mm; it is not a lock. The tunable air cushion only controls end-of-stroke deceleration, so neither feature will hold a load in place without continuous air pressure.
