About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X500-30
The AirTAC MBLCJ50X500-30 is a compact double-acting aluminum mini cylinder featuring a rear travel stopper that creates a usable stroke window of 470 to 500 mm. It generates 981 N of push force and 881 N of pull force at 0.5 MPa, making it well-suited for moving heavy jigs or executing long-travel positioning tasks in confined assembly spaces.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model incorporates a screw-tunable adjustable air cushion at both ends to decelerate heavy 500 mm moves safely. The riveted rolling-packed aluminum barrel and grease-retaining two-way piston seal lock in lubrication for long service life. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors without modification. The rear adjuster acts purely as a mechanical travel stop and does not 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.
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 MBLCJ50X500-30 Is Used
Injection Mold Ejection
Provides the 981 N push force needed to eject heavy plastic parts from long-stroke molds, using the 470-500 mm adjustable window to dial in the exact ejection reach.
Conveyor Pallet Stopping
Decelerates fast-moving packaging line pallets at the end of a 500 mm travel, relying on the tunable air cushion to protect the end covers from impact shock.
Long-Travel Press Feeding
Pushes metal blanks into a forming press over a half-meter stroke, where the compact riveted aluminum body fits tight feeder cell spaces better than ISO 15552 units.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X500-30 the Right Cylinder?
When sizing this 50 mm bore cylinder, stepping down to a 40 mm bore reduces the output to 628 N push at 0.5 MPa, while stepping up to a 63 mm bore increases it significantly to 1558 N. Choose this MBLCJ variant over the fixed-stroke MBLC when you need to fine-tune the end position within that 470-500 mm window. Keep in mind the rear stopper and the adjustable air cushion only manage travel limits and end-deceleration; neither will hold a load pneumatically without continuous air supply. Mounting is limited to Basic, FA flange, or LB foot styles as there is no back-cover or SDB pivot option. For replacements, match the 50 mm bore, 500 mm stroke, 30 mm adjust code, G1/4 port, PT thread form, and confirm no magnet is present. Because the stroke is 500 mm on a Ø16 mm rod, an external guide rail is strongly recommended to prevent rod bending under side loads.
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 MBLCJ50X500-30 FAQ
At 0.5 MPa, this 50 mm bore double-acting cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push force reaches 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
The rear stopper allows you to trim up to 30 mm of travel, creating a usable stroke window of 470 to 500 mm. The adjustable air cushion is a separate screw-tunable mechanism that controls end-of-stroke deceleration to protect the end covers. The stopper sets the travel end position but does not lock or hold the load pneumatically.
