About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ63X150-75
The AirTAC MBLCJ63X150-75 is a double-acting, single-rod mini cylinder engineered for heavy-duty compact automation, delivering 1558 N of push force at 0.5 MPa. It features a 63 mm bore, a 150 mm standard stroke, and a rear travel adjuster that lets you trim the stroke by up to 75 mm, creating a precise usable end-position window of 75 to 150 mm. Tunable air cushions at both ends absorb kinetic energy to prevent end-cover damage during high-speed moves, which is critical for a 318 kgf class actuator.
This specific configuration uses a default PT tapered port thread and a Ø16 mm hard-chrome plated carbon-steel rod with an M14x1.5 end thread. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot support CMSG, DMSG, or EMSG position sensing. The riveted aluminum barrel keeps weight down, while the grease-retaining piston seal ensures long service life. Remember the rear stopper sets the travel limit and the cushion decelerates the load; neither component mechanically locks the rod in place.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ63X150-75 Is Used
Stamping Press Ejection
Provides 1558 N of push force to eject heavy sheet metal blanks from progressive stamping dies, using the 75 mm rear adjuster to match the exact knockout depth.
Palletizer Stopper Gate
Decelerates heavy pallet loads at the end of a 150 mm stroke using the twin adjustable air cushions, preventing impact damage to the end covers during high-speed conveying.
Woodworking Panel Press
Applies up to 318 kgf of theoretical clamping force to hold MDF panels steady during routing, relying on the Ø16 mm hard-chrome rod to resist deflection.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ63X150-75 the Right Cylinder?
Select this 63 mm bore actuator when your application requires substantial push and pull forces (1558 N / 1457 N at 0.5 MPa) within a 75 to 150 mm stroke window. If you need less force, stepping down to the 50 mm bore yields 981 N of push force. If you require even greater thrust, the 63 mm is the largest available frame in this series, so you would need to explore alternative ISO 15552 profiles. Choose the MBLCJ over the MBLJ when your moving masses demand tunable air cushioning rather than a fixed rubber bumper, or over the MBLC when you need the rear travel adjuster to fine-tune the end position.
When ordering a replacement, verify the 63 mm bore, 150 mm stroke, 75 mm adjust code, G1/4 port size, PT thread form, and Basic mounting style. Mounting is strictly limited to Basic, FA flange, or LB foot configurations; this series does not support SDB pivot or back-cover mounts. Because the overall length equals A + 2 x stroke + adjust, confirm your spatial envelope. The rear adjuster acts as a travel stop, not a load-holding brake—external locking mechanisms are required if the rod must hold position against a load without live air pressure.
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 MBLCJ63X150-75 FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push force increases to 2181 N, with a maximum theoretical output of 318 kgf at 1.0 MPa. The rear adjuster allows you to trim up to 75 mm from the 150 mm standard stroke, yielding a usable end-position window of 75 to 150 mm.
This specific SKU lacks the -S suffix, meaning it has no internal magnet and cannot be used with CMSG, DMSG, or EMSG sensor switches. Additionally, while the adjustable air cushion tunes end-of-stroke deceleration to protect the end covers, it is not a lock. The rear stroke adjuster is a travel stop, not a brake, so the rod will drift if air pressure is removed.
