About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X200-50S
The AirTAC MBLCJ50X200-50S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. The rear stopper trims up to 50 mm of travel, yielding a usable stroke window of 150-200 mm. Delivering 981 N push and 881 N pull force at 0.5 MPa, this 200 mm unit suits mid-range positioning tasks requiring precise end-deceleration.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable air cushioning to absorb kinetic energy at the stroke extremes, protecting the end covers during heavier cycles. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod withstand industrial wear. A built-in magnet (-S) enables position detection, compatible with AirTAC CMSG reed switches as well as DMSG and EMSG solid-state electronic sensors.

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 MBLCJ50X200-50S Is Used
Injection Mould Ejection
Provides 981 N of push force at 0.5 MPa to eject plastic parts, using the 150-200 mm adjustable window to time the exact ejection stroke and the air cushion to prevent harsh impacts.
Pallet Diverting Arm
Drives a diverting mechanism on a packaging line, where the 1374 N output at 0.7 MPa handles heavy cartons and the tunable cushioning softens the 200 mm travel stop.
Bending Press Feed
Feeds sheet metal into a bending press, relying on the DMSG solid-state sensor to confirm the 16 mm chrome rod position and the adjustable stopper to dial in the material depth.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X200-50S the Right Cylinder?
Stepping down to a 40 mm bore reduces output to 628 N push at 0.5 MPa, whereas stepping up to a 63 mm bore yields 1558 N push for heavier loads. Choose this MBLCJ over the MBLJ when your moving mass demands tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC if you need the 150-200 mm rear travel adjustment window rather than a fixed length.
Remember the rear stopper sets the travel end but does not hold the load; the air cushion only decelerates and neither acts as a lock. Mounting is limited to Basic, FA flange, or LB foot (no SDB pivot or back-cover options). Overall length extends by the adjustment travel. For exact replacement matching: 50 mm bore, 200 mm stroke, 50 mm adjust code, G1/4 port, PT thread, Basic mount, with S magnet. As this stroke is 200 mm, use an external guide 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 MBLCJ50X200-50S FAQ
At 0.5 MPa it provides 981 N push and 881 N pull. At 0.7 MPa the push force is 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
The rear adjustable stroke is a mechanical travel stopper that lets you trim the usable window down to 150 mm from the 200 mm nominal length. The adjustable air cushion is a screw-tunable valve that controls end-of-stroke deceleration. Neither holds the load in place; you need external locking for position holding.
