About the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ63X160-75S
The AirTAC MBLJ63X160-75S is a double-acting aluminum mini cylinder featuring a rear stroke adjuster that allows you to trim the extend travel by up to 75 mm, creating a usable end-position window of 85 to 160 mm. Driven by a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating, it delivers 1558 N of push force and 1457 N of pull force at 0.5 MPa. This specific 160 mm stroke is well suited for mid-range indexing or pressing tasks where the exact contact point varies by product type.
Equipped with a built-in magnet (-S), this unit supports AirTAC CMSG reed and DMSG or EMSG solid-state sensor switches for rod-position detection. The riveted rolling-packed barrel uses a grease-retaining piston seal, while a fixed rubber bumper absorbs end-of-stroke impact. Note that the rear stopper and bumper only set and soften the travel limit; they do not lock the load without continuous air pressure. Overall length equals A + 2 x stroke + adjust, which is longer than a fixed MBL variant.

Where the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ63X160-75S Is Used
Packaging Palletizers
Provides the 1558 N push force needed to lift and position heavy corrugated cardboard blanks, with the 85-160 mm adjuster window allowing quick adaptation to varying pallet heights.
Injection Mold Ejection
Sets precise ejection reach for plastic parts; the 75 mm rear stopper tunes the endpoint on the fly without moving the cylinder body during mold changeovers.
Woodworking Panel Presses
Applies consistent clamping pressure across cabinet doors, using the built-in magnet to trigger a DMSG electronic sensor exactly when the 160 mm travel reaches the tuned stop.
Is the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ63X160-75S the Right Cylinder?
When sizing this 63 mm bore actuator, consider stepping down to the 50 mm bore if your application requires less energy, as it provides 981 N of push force at 0.5 MPa. If you need maximum thrust, this 63 mm bore is the largest available in the MBLJ range, yielding 318 kgf at 1.0 MPa. Choose this adjustable MBLJ over a fixed-stroke MBL when you need on-machine end-position tuning without swapping hardware, or upgrade to an MBLCJ if your mass requires adjustable air cushions rather than a fixed rubber bumper.
The rear adjuster functions purely as a mechanical travel stop and must not be relied upon to hold a load pneumatically. Mounting is restricted to Basic, FA flange, or LB foot styles; there is no SDB pivot or back-cover option. To replace this unit, match the 63 mm bore, 160 mm stroke, 75 mm adjust code, G1/4 port, PT thread, and the -S magnet. Because the stroke exceeds 300 mm on larger variants, ensure external side-load guides are used to protect the 16 mm rod from bending, even at this 160 mm length.
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 MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ63X160-75S 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 theoretical maximum of 318 kgf at 1.0 MPa. The 75 mm rear adjuster allows you to trim the stroke, providing a usable end-position window from 85 mm to 160 mm.
No, the rear screw is a travel stop that sets the end position; it does not lock or hold the load without live air pressure. The -S designation means a built-in magnet is fitted, allowing you to mount AirTAC CMSG reed switches or DMSG and EMSG electronic sensors along the barrel to detect the rod position.
