About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X200-20
The AirTAC MBLCJ50X200-20 is a compact double-acting mini cylinder featuring a Ø50 mm bore and a 200 mm stroke. It combines a rear travel stopper that trims up to 20 mm, giving a usable stroke window of 180-200 mm, with screw-tunable air cushions at both ends. Delivering 981 N push and 881 N pull at 0.5 MPa, it is built for heavier mid-stroke actuation. The riveted aluminum barrel and 20 µm hard-chrome plated carbon-steel rod withstand industrial wear.
This SKU uses a PT (tapered) port thread and a G1/4 port. It lacks the -S magnet code, meaning it cannot accept a CMSG, DMSG, or EMSG position sensor. The adjustable cushion damps kinetic energy near the stroke ends to protect the covers, while the rear adjuster acts purely as a mechanical travel stop—neither component locks 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 MBLCJ50X200-20 Is Used
Injection Mold Ejection
Provides 981 N of push force at 0.5 MPa to eject heavy plastic parts, using the 20 mm rear stroke trim to precisely set the ejection end-position without moving the machine platen.
Pallet Stopper Arm
Halts 200 mm travel conveyor pallets; the tunable air cushion decelerates the 1374 N peak force smoothly, preventing impact damage to the aluminum end covers.
Press Fit Bushing
Drives bushings into housings with a controlled 180-200 mm stroke window, relying on the grease-retaining piston seal to maintain consistent friction over high cycle counts.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X200-20 the Right Cylinder?
Delivering 981 N at 0.5 MPa, step down to the Ø40 bore if your load requires only 628 N, or step up to the Ø63 bore for 1558 N. Choose this MBLCJ over the MBLJ when your speeds demand tunable air cushioning instead of a fixed rubber bumper, or over the MBLC if you need the 180-200 mm adjustable end-position window. For replacements, match the 50 mm bore, 200 mm stroke, 20 mm adjust code, G1/4 PT thread, and Basic mounting. Note that mounting is limited to Basic, FA, or LB; no SDB or back-cover options exist. The cylinder cannot hold position without live air, so use an external lock for static holding.
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 MBLCJ50X200-20 FAQ
At 0.5 MPa, the push force is 981 N and the pull force is 881 N. At 0.7 MPa, the push force is 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
No. This specific SKU lacks the -S code, meaning no built-in magnet is fitted. You must select an MBLCJ model with the -S suffix to use AirTAC CMSG (reed) or DMSG/EMSG (electronic) sensors.
