About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ63X175-100
The AirTAC MBLCJ63X175-100 is a compact double-acting mini cylinder featuring a rear travel stopper that creates a usable 75-175 mm stroke window from the 175 mm nominal length. A screw-tunable adjustable air cushion at both ends absorbs heavy kinetic energy, protecting the end covers during high-speed moves. Delivering 1558 N of push force and 1457 N of pull force at 0.5 MPa, this 63 mm bore unit is built for substantial actuation tasks.
The body uses a riveted rolling-packed aluminum barrel paired with a heterogeneous two-way grease-retaining piston seal, ensuring stable lubrication over long cycles. Its carbon-steel rod features 20 µm hard-chrome plating to resist corrosion and scoring under side loads. Because this SKU lacks the -S magnet code, it cannot accept an AirTAC CMSG, DMSG, or EMSG position sensor; external limit switches are required for end-of-travel detection.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ63X175-100 Is Used
Injection Mold Clamping
Supplies 1558 N of push force at 0.5 MPa to secure injection mold halves, using the 75-175 mm stroke window to fine-tune the exact clamping distance without shimming.
Heavy Press Assembly
Drives bearings into housings on an automated press line, utilizing the dual adjustable air cushions to decelerate 318 kgf maximum loads smoothly before impact.
Pallet Diverter Stop
Acts as a travel stop for heavy pallets on a packaging conveyor, with the rear stopper absorbing kinetic energy while the cushion protects the end cover from shock.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ63X175-100 the Right Cylinder?
This 63 mm bore provides the maximum thrust in the MBL family, generating 1558 N push at 0.5 MPa. If your application requires less force, stepping down to the 50 mm bore yields 981 N push, saving space and air consumption. As the largest available size, there is no larger bore to step up to within this series. Compared to the MBLJ, the MBLCJ adds tunable pneumatic cushioning rather than a fixed rubber bumper, making it superior for decelerating heavy loads. Remember that the rear adjuster sets the travel end and the cushion only decelerates; neither will hold a load in place without live air pressure, so an external locking mechanism is needed for position holding.
Mounting is restricted to Basic, FA flange, or LB foot brackets; SDB pivot and back-cover options are not available on this profile. The overall length extends to A + 2 x stroke + adjust, so plan your machine envelope accordingly. This specific SKU uses a default PT tapered port thread and a G1/4 port size. When replacing, verify the 63 mm bore, 175 mm stroke, 100 mm adjust code, PT thread, and the absence of a magnet. At 175 mm stroke, the 16 mm rod is robust, but for strokes approaching the 500 mm maximum, always add an external guide to prevent rod bending.
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 MBLCJ63X175-100 FAQ
At 0.5 MPa, this 63 mm bore cylinder delivers 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push force increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
The rear adjuster physically limits the stroke, trimming up to 100 mm of travel to set a precise 75-175 mm end position. The adjustable air cushion is a screw-tunable valve that bleeds trapped air to decelerate the piston near the end caps. Neither component locks or holds the load; they only control travel and speed.
