About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X150-20
The AirTAC MBLCJ32X150-20 is a compact double-acting aluminum mini cylinder featuring a rear travel 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 rear stopper allows you to trim up to 20 mm of travel, creating a usable stroke window of 130 to 150 mm. This specific reach is well-suited for mid-range indexing and component transfer tasks.
Unlike the fixed rubber bumper found on the base MBLJ series, the screw-tunable air cushion on this unit allows you to dial in end-of-stroke deceleration, safely absorbing kinetic energy from faster moves to protect the end covers. The riveted rolling-packed barrel houses a Ø12 mm carbon-steel rod with 20 µm hard-chrome plating and a grease-retaining piston seal. Because this SKU lacks the -S suffix, it is built without a magnet and cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X150-20 Is Used
PCB Router Gantry
Drives a routing spindle across a 130-150 mm cutting path, using the tunable air cushion to decelerate the 402 N thrust smoothly at stroke ends without jarring the spindle bearings.
Bottle Capper Heads
Trims 20 mm off the standard 150 mm downward travel to perfectly seat aluminum caps, relying on the rear stopper to set the exact final height for consistent torque application.
Carton Flap Folder
Actuates a mechanical flap-folding arm on a packaging line, where the adjustable cushion absorbs the kinetic energy of the 346 N retract cycle to prevent slamming against the cylinder body.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X150-20 the Right Cylinder?
Choose this 32 mm bore when you need roughly 402 N of push force at 0.5 MPa. If your application is lighter, stepping down to the 25 mm bore yields 245 N of push force; if you need more muscle, stepping up to the 40 mm bore provides 628 N. Compared to the MBLC (fixed stroke), this MBLCJ gives you the 130-150 mm rear adjustment window, and compared to the MBLJ, it upgrades you from a fixed bumper to a tunable cushion. Remember the adjuster is a travel stop, not a lock—it cannot hold a load in place without live air pressure.
When replacing this unit, match the 32 mm bore, 150 mm stroke, 20 mm adjust code, G1/8 port, and default PT thread. Mounting is limited to Basic, FA flange, or LB foot styles; there is no SDB pivot or back-cover option. With a 150 mm stroke on a Ø12 mm rod, external guiding is recommended to prevent rod bending and premature seal wear under side loads. The overall length calculates as A + 2 x stroke + adjust.
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 MBLCJ32X150-20 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
No. The rear adjuster is a travel stop that sets the end position, not a lock, and the air cushion only decelerates motion; neither will hold a load without continuous air pressure. Additionally, because this SKU lacks the -S magnet option, it cannot be fitted with CMSG, DMSG, or EMSG sensors for position detection.
