About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X225-20S
The AirTAC MBLCJ32X225-20S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 402 N of push force and 346 N of pull force at 0.5 MPa. The integrated magnet (-S) allows for CMSG reed or DMSG/EMSG electronic sensor tracking. With a 225 mm stroke and a 20 mm rear trimmer, the usable end-position window spans 205 to 225 mm.
Unlike the fixed rubber bumper found on an MBLJ, this model uses screw-tunable air cushions to decelerate heavier loads smoothly at stroke ends, protecting the end covers. The riveted rolling-packed aluminum barrel and 20 µm hard-chrome plated carbon-steel rod resist wear, while the heterogeneous two-way grease-retaining piston seal maintains lubrication. The rear stopper sets the travel end but does not lock the load; external guides are recommended for this 225 mm stroke to prevent rod bending on a 12 mm rod.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X225-20S Is Used
PCB Router Z-Axis
Lifts and lowers a high-speed spindle router. The 205-225 mm window precisely sets the Z-axis depth, while the tunable air cushion prevents spindle bounce at the 225 mm stroke end.
Textile Take-Up Tensioner
Maintains web tension on a loom. The 402 N force at 0.5 MPa balances fabric pull, and the rear adjuster allows exact positioning of the dancer roller without changing the base stroke.
Carton Flap Folder
Folds major flaps on a packaging line. The adjustable cushion slows the 346 N pull force near the end of the 225 mm travel, preventing mechanical shock to the linkage.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X225-20S the Right Cylinder?
This 32 mm bore provides 402 N push at 0.5 MPa. If your application needs less force, the 25 mm bore offers 245 N; if you require more power, stepping up to the 40 mm bore yields 628 N. Choose the MBLCJ over the MBLJ when your moving mass requires tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC when you need that rear travel-stop to trim the 205-225 mm window.
Remember that neither the rear adjuster nor the air cushion acts as a lock; the rod will drift without live air pressure, so use an external holding device if mid-stroke positioning is required. Mounting is limited to Basic, FA (flange), or LB (foot) styles, as this series lacks a back-cover or SDB pivot option. For an exact replacement, match the 32 mm bore, 225 mm stroke, 20 mm adjust code, G1/8 port, PT thread, and the -S magnet specification.
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 MBLCJ32X225-20S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N push and 346 N pull force. At 0.7 MPa, the push force is 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa.
The rear stroke adjuster is a mechanical travel stop that trims the usable stroke window from 205 to 225 mm. The adjustable air cushion is a separate needle valve that tunes end-of-stroke deceleration. Neither holds the load; the rod drifts without air pressure.
