About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X150-75
The AirTAC MBLCJ50X150-75 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It trims up to 75mm of rear travel, giving an exact usable window of 75-150mm. Driven by a Ø16 rod through a G1/4 port, it outputs 981N push and 881N pull at 0.5MPa, making it highly effective for moving heavier jigs or mid-scale machine tooling.
Unlike the fixed rubber bumper on an MBLJ, this model uses screw-tunable air cushions to decelerate the piston near each end cover, absorbing kinetic energy from fast 150mm moves. Note this specific SKU lacks the -S magnet, meaning it cannot host a CMSG or DMSG position sensor. The riveted rolling-packed barrel and 20um hard-chrome plated carbon-steel rod provide durable wear resistance, while the rear stopper sets the travel end without mechanically locking 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.
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 MBLCJ50X150-75 Is Used
CNC Lathe Bar Feeder
Pushes heavy bar stock into the spindle; the 981N thrust handles dense steel, while the tunable air cushion prevents end-cover damage during rapid 150mm loading strokes.
Injection Mold Ejector
Trims the ejection stroke between 75 and 150mm to clear deep mold cavities, using the screw-tunable cushion to protect fragile plastic parts from sudden stripping forces.
Pallet Divert Arm
Swings heavy transfer arms on packaging lines; the 881N pull force retracts the 16mm rod reliably, while the rear stopper sets precise mechanical endpoints.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X150-75 the Right Cylinder?
Stepping down to the 40mm bore drops the 0.5MPa push force to 628N, whereas stepping up to the 63mm bore raises it to 1558N. Choose the MBLCJ over the MBLJ when your moving mass requires tuned deceleration rather than a hard bumper impact, or over the MBLC when you need that 75mm rear travel trim window. Remember, the adjuster is a travel stop and the cushion only decelerates; neither will hold a load statically without live air pressure.
Mounting is limited to Basic, FA flange, or LB foot styles, as there is no back-cover or SDB pivot option for this series. The overall length extends by the 75mm adjuster, so verify your envelope. To replace this unit, match the 50mm bore, 150mm stroke, 75mm adjust code, G1/4 port, PT thread, and confirm no magnet is required.
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 MBLCJ50X150-75 FAQ
At 0.5MPa, this 50mm bore cylinder provides 981N of push force and 881N of pull force. At 0.7MPa, the push force reaches 1374N. The maximum theoretical force is 200kgf at 1.0MPa.
The rear stroke adjuster is a mechanical travel stop that limits the piston's end position within a 75-150mm window. The adjustable air cushion is a screw-tunable valve that bleeds trapped air to decelerate the load near the end covers. Neither acts as a lock to hold position.
