About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X200-30S
The AirTAC MBLCJ50X200-30S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 981 N of push force and 881 N of pull force at 0.5 MPa. The rear stopper allows you to trim up to 30 mm of travel, creating a precise 170-200 mm usable stroke window for exact end-positioning.
Unlike the fixed rubber bumper found on the MBLJ series, the screw-tunable air cushion on this SKU decelerates heavier loads near the stroke ends to protect the end covers. The -S code means a built-in magnet is fitted for CMSG reed or DMSG/EMSG electronic sensors. The Ø16 hard-chrome plated carbon-steel rod and riveted barrel provide durable, grease-retaining operation in tight spaces.

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 MBLCJ50X200-30S Is Used
Injection Mold Ejection
Provides the 981 N push force required to eject dense plastic parts from molds, using the 170-200 mm adjustable window to time the exact ejection stroke.
Packaging Press Sealing
Tunes the end-of-stroke air cushion to softly press carton flaps without crushing the contents, handling high-speed repetitive cycles up to 800 mm/s.
Woodworking Panel Feed
Pushes heavy wood panels into a routing station, relying on the DMSG electronic sensor to confirm the 200 mm extension before the cutter engages.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X200-30S the Right Cylinder?
Select this 50 mm bore when you need 981 N push force at 0.5 MPa over a 200 mm travel window. If your payload is lighter, step down to the 40 mm bore (628 N push); if you need to move heavier jigs, step up to the 63 mm bore (1558 N push). The 30 mm rear adjuster sets the travel end but does not lock the load, while the cushion only decelerates—neither holds position without live air.
Mounting is limited to Basic, FA flange, or LB foot styles (no SDB pivot or back-cover options). The overall length extends by A + 2 x stroke + adjust. To replace this unit, match the 50 mm bore, 200 mm stroke, 30 mm adjust code, G1/4 port, PT thread, and the -S magnet. Since this stroke is 200 mm, the small 16 mm rod is susceptible to side-loading; use an external guide rail to prevent rod bending.
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 MBLCJ50X200-30S 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.
The 30 mm rear adjuster is a mechanical travel stop that sets your usable stroke window between 170-200 mm. The adjustable air cushion is a separate screw that controls end-of-stroke deceleration. Neither acts as a lock to hold the load.
