About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X300-75
The AirTAC MBLCJ32X300-75 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 push and 346 N pull force at 0.5 MPa. The rear stopper allows you to trim up to 75 mm of travel, creating a usable 225-300 mm stroke window. This 300 mm stroke length is well-suited for routing components across wide machine spans. Because this specific SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor.
The integrated adjustable air cushion lets you screw-tune end-of-stroke deceleration, absorbing kinetic energy to protect the end covers—a significant upgrade over the fixed rubber bumper found on the base MBLJ series. Keep in mind the adjuster is a travel stop, not a lock; it sets the end position but does not hold the load. With a 300 mm stroke on a Ø12 mm rod, side-load forces can cause rod drift and bending, so an external guide rail is strongly recommended to prevent premature seal wear.

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 (Ø32mm)

|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 MBLCJ32X300-75 Is Used
Textile Loom Beam Indexing
Drives the 300 mm traversal of heavy weaving beams on a textile loom, using the 75 mm rear adjuster to dial in exact 225 mm takedown positions while the air cushion prevents end-cover impact.
CNC Lathe Conveyor Diverter
Pushes finished turned parts across a 300 mm gap into a sorting chute, relying on the 402 N push force and tunable deceleration to prevent parts from bouncing at the stroke end.
Packaging Carton Flap Folder
Folds large corrugated carton flaps over a wide 300 mm arc; the adjustable stroke window allows precise flap alignment without repositioning the entire cylinder mount.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X300-75 the Right Cylinder?
When sizing this 32 mm bore cylinder, consider stepping down to the 25 mm bore (offering 245 N push at 0.5 MPa) for lighter loads, or stepping up to the 40 mm bore (providing 628 N push at 0.5 MPa) if your payload requires more force. Choose this MBLCJ model over the MBLJ when your moving mass demands tunable pneumatic deceleration rather than a fixed rubber bumper. If your machine cycle is fixed and never varies, the MBLC version provides the same cushioning without the rear adjuster.
Remember that neither the rear travel stopper nor the adjustable cushion acts as a mechanical lock; the rod will drift if air pressure is removed, so external holding mechanisms are required for safety. Mounting is limited to Basic, FA flange, or LB foot brackets—this series omits the SDB pivot and back-cover options. For a direct replacement, match the 32 mm bore, 300 mm stroke, 75 mm adjust code, G1/8 port, PT thread, and note the absence of the -S magnet. The overall length equals A + 2 x 300 + 75 mm.
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 MBLCJ32X300-75 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 increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa operating pressure.
The rear adjuster physically limits the piston's travel, allowing you to trim up to 75 mm of movement for a usable 225-300 mm stroke window. The adjustable air cushion screw tunes the end-of-stroke deceleration rate. Neither feature locks or holds the load; the rod drifts without live air pressure.
