About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X175-75
The AirTAC MBLCJ40X175-75 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. The 75 mm rear adjuster creates a usable stroke window from 100 mm to 175 mm, letting you fine-tune the end position without moving the cylinder body.
This model uses a G1/4 port and a Ø16 carbon-steel rod with 20 µm hard-chrome plating for wear resistance. The riveted rolling-packed aluminum barrel and grease-retaining piston seal keep lubrication in, extending cycle life. Because this SKU lacks the -S magnet code, it cannot host a CMSG, DMSG, or EMSG position sensor. The tunable air cushion allows you to dial in end-of-stroke deceleration for heavier loads, protecting the end covers from impact—a clear upgrade over the fixed rubber bumper found on the MBLJ series.

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 (Ø40mm)

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 MBLCJ40X175-75 Is Used
CNC Lathe Bar Feeder
Pushing 40 mm steel bar stock into a lathe collet uses the 628 N push force, while the adjustable air cushion halts the 175 mm travel smoothly to prevent mechanical shock to the machine spindle.
Packaging Carton Erector
Forming heavy corrugated cardboard flaps requires precise end-position tuning; the 75 mm rear adjuster dials the stroke down to 100 mm for shorter carton formats without relocating the cylinder.
Pallet Stopper Gate
Halting loaded pallets on a conveyor line relies on the 528 N pull force to retract the gate, with the dual cushions absorbing the kinetic energy of heavy pallet impacts at each stroke end.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X175-75 the Right Cylinder?
Stepping down to the 32 mm bore drops the 0.5 MPa push force to 402 N, which may be insufficient for your payload, while stepping up to the 50 mm bore raises it to 981 N for heavier masses. Choose the MBLCJ over the MBLJ when your moving mass requires screw-tunable pneumatic deceleration rather than a fixed rubber bumper. If you need a fixed stroke length, consider the MBLC series instead.
Remember that the rear adjuster is a mechanical travel stop, not a load lock; it sets the end position but will not hold a suspended load without live air pressure. Mounting is limited to Basic, FA, or LB styles, as this series has no SDB pivot or back-cover options. For a drop-in replacement, match the 40 mm bore, 175 mm stroke, 75 mm adjust code, G1/4 port, PT thread, and confirm no magnet is required. Since the 175 mm stroke is substantial, use an external guide to prevent rod bending under side-loads.
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 MBLCJ40X175-75 FAQ
At 0.5 MPa, it provides 628 N push and 528 N pull force. At 0.7 MPa, the push force reaches 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
This specific SKU lacks the -S magnet code, so it cannot accept CMSG, DMSG, or EMSG position switches. The adjustable air cushion is a screw-tunable valve that bleeds trapped air at stroke ends to decelerate the piston; it is not a mechanical lock or a substitute for external load holding.
