About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X225-10
The AirTAC MBLCJ50X225-10 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 at 0.5 MPa, making it well-suited for moving heavier jigs or workpieces over its 225 mm travel. The rear stopper lets you trim up to 10 mm, creating a precise 215-225 mm usable stroke window for exact end-of-travel positioning.
Unlike the fixed rubber bumper found on the base MBLJ, the screw-tunable air cushion on this unit allows you to dial in end-of-stroke deceleration, protecting the end covers during fast, heavy movements. Note that this SKU is supplied without a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors. The 20 um hard-chrome plated carbon-steel rod and grease-retaining piston seal ensure durable, long-term operation.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X225-10 Is Used
Stamping Press Feed
Pushes metal blanks into a progressive die with 981 N of force, using the 215-225 mm stroke window to time the exact insertion depth.
Heavy Fixture Clamping
Secures large welded automotive frames, relying on the adjustable air cushion to decelerate the 225 mm travel and prevent impact shock.
Pallet Indexing Stop
Acts as a hard stop for heavy conveyor pallets, using the 10 mm rear stroke adjuster to dial in the exact stopping position without repositioning the whole mount.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X225-10 the Right Cylinder?
Select this 50 mm bore when your application requires approximately 981 N of push force at 0.5 MPa. If you need less force, the 40 mm bore offers 628 N; if you need more, the 63 mm bore provides 1558 N. Choose this MBLCJ variant over the MBLJ when your moving mass requires tunable pneumatic deceleration rather than a simple fixed bumper, or over the MBLC when you need the 10 mm rear stroke adjustment to fine-tune the travel end.
Remember that the rear adjuster is a travel stop, and the air cushion only decelerates; neither component locks or holds the load, so external locking mechanisms are required for static position holding. Mounting is limited to Basic, FA (flange), or LB (foot) styles, as no back-cover or SDB pivot options exist for this series. The direct replacement match is a 50 mm bore, 225 mm stroke, 10 mm adjust code, G1/4 port, PT thread, with no magnet. Because the stroke is 225 mm, the 16 mm rod is susceptible to side-loading; always use an external guide rail to prevent rod bending and premature seal wear.
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 MBLCJ50X225-10 FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push force increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa operating pressure.
This specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors. Additionally, the 10 mm rear adjuster is a travel stop that sets the 215-225 mm stroke window, and the adjustable air cushion only controls deceleration; neither feature locks or holds the load in place.
