About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X160-30
The AirTAC MBLCJ40X160-30 is a compact double-acting mini cylinder featuring a riveted aluminum barrel and a Ø16 mm hard-chrome plated carbon-steel rod. It generates 628 N of push force and 528 N of pull force at 0.5 MPa. A rear adjuster allows you to trim up to 30 mm of travel, creating a usable stroke window of 130 to 160 mm, ideal for optimizing a 160 mm machine cycle.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model incorporates a screw-tunable adjustable air cushion at both ends to decelerate heavier loads smoothly. The rear stroke stopper sets the travel end position but does not mechanically hold the load in place, meaning external locking mechanisms are required for static positioning. This SKU is supplied without a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 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 MBLCJ40X160-30 Is Used
Spindle Feed Positioning
Drives the Z-axis feed on a compact CNC drilling unit, using the 628 N push force to lower the tool block while the air cushion prevents hard end-impact at the 160 mm travel limit.
Pallet Diverter Arm
Actuates a routing flap on a 24V conveyor line, utilizing the 130-160 mm adjustable stroke window to fine-tune the flap angle for varying box widths without repositioning the cylinder.
Pneumatic Rivet Press
Applies downward pressure on a multi-point riveting fixture, relying on the tunable cushion to gently seat the 16 mm rod before the riveting force peaks.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X160-30 the Right Cylinder?
If your force requirements are lower, stepping down to the 32 mm bore yields 402 N of push force at 0.5 MPa, whereas moving up to the 50 mm bore provides 981 N for heavier payloads. Choose the MBLCJ over the fixed-stroke MBLC when you need precise end-position tuning, or over the MBLJ when your moving mass requires tunable deceleration rather than a fixed bumper impact.
Remember that the rear adjuster acts purely as a travel stop and the air cushion only manages deceleration; neither function locks the rod against drift. Mounting is limited to Basic, FA (flange), or LB (foot) styles, as no SDB pivot or back-cover options exist for this body. To match this exact replacement, specify a 40 mm bore, 160 mm stroke, 30 mm adjust code, G1/4 port, PT thread, and no magnet (non-S).
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 MBLCJ40X160-30 FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. The operating pressure range is 0.15 to 1.0 MPa.
The rear adjustable stroke lets you mechanically trim the travel window down to 130 mm from the 160 mm nominal stroke, acting as a hard travel stop. The adjustable air cushion uses a screw needle to control exhaust flow for end-of-stroke deceleration. Neither holds the load in place; they only manage travel limits and impact speed.
