About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X100-75S
The AirTAC MBLCJ40X100-75S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 628N push and 528N pull force at 0.5MPa, making it highly effective for mid-range actuation. The rear stopper allows you to trim up to 75mm of travel, creating a precise usable stroke window of 25-100mm for exact end-positioning.
Unlike the fixed rubber bumper found on the base MBLJ series, the screw-tunable air cushion on this unit decelerates heavier loads at high speeds, protecting the end covers from impact shock. The riveted rolling-packed barrel and 20um hard-chrome plated carbon-steel rod resist wear, while the built-in magnet (-S) enables position detection with CMSG reed or DMSG/EMSG electronic sensors. Remember, the cushion only governs end-of-stroke speed; it is not a mechanical lock.

| 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 MBLCJ40X100-75S Is Used
PCB Router Z-Axis
Governs the vertical plunge of a high-speed PCB depaneling router, using the 25-100mm stroke window to dial in the exact cutting depth while the air cushion softens the rapid tool return.
Bottle Capper Heads
Applies 628N of downward clamping force to spin aluminum caps onto filled bottles, utilizing the tunable cushion to prevent sudden mechanical stops that could shatter the glass containers.
Pallet Diverter Gate
Pivots a mechanical diverter arm on a packaging conveyor, where the 0.5MPa thrust reliably redirects heavy product pallets without bouncing them off the guide rails.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X100-75S the Right Cylinder?
Stepping down to the 32mm bore yields 402N push force at 0.5MPa, whereas moving up to the 50mm bore provides 981N, giving you clear sizing flexibility. Choose this MBLCJ over the MBLJ when your moving mass requires active deceleration rather than a hard bumper stop, or over the MBLC if you need that 25-100mm travel window rather than a fixed 100mm stroke.
The rear adjuster sets the travel end and the cushion governs deceleration, but neither holds the load pneumatically; a separate external guide or lock is required for position holding. Mounting is limited to Basic, FA flange, or LB foot styles as there is no SDB pivot or back-cover option. To replace this SKU exactly, match the 40mm bore, 100mm stroke, 75mm adjust code, G1/4 port, PT thread, and the -S magnet.
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 MBLCJ40X100-75S FAQ
At 0.5MPa, this 40mm bore cylinder provides 628N push force and 528N pull force. At 0.7MPa, the push force increases to 880N. The maximum theoretical force is 128kgf at 1.0MPa operating pressure.
The adjustable stroke is a rear mechanical stopper that trims the rod travel from 100mm down to 25mm. The adjustable air cushion is a separate screw-tunable valve that controls exhaust flow to decelerate the load at the stroke ends. Neither system locks or holds the load in place pneumatically.
