Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø40mm bore and 160mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-50S
Where a fixed-stroke MAC cylinder would leave you stacking spacers, the MACJ40X160-50S lets maintenance screw the extend stroke down by up to 50 mm from the ordered 160 mm - an effective 110-160 mm band. Output is solid mid-range: 628 N push and 528 N pull at 0.5 MPa, 880 N at 0.7 MPa, with a practical working figure near 377 N once you keep 40 percent in reserve.
Variable air cushions at both ends let you raise line speed toward 800 mm/s without pounding the aluminium covers, and the standard-built magnet accepts CMSG, DMSG and EMSG switches off the shelf. The stainless tube and chrome-plated rod hold up in wet or dusty plants.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-50S Is Used
Case ejector on a sealer
Different case heights are absorbed by screwing the stroke within the 50 mm window instead of repositioning the whole ejector station.
Woodworking hold-down
About 377 N of steady working force clamps boards against a fence for routing, while cushions prevent the clamp jaw from jolting the workpiece at stroke end.
Tote divider indexing
A DMSG switch confirms the divider blade is fully retracted before totes advance down the accumulation lane.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-50S the Right Cylinder?
Size check: the 32 mm bore tops out at 402 N at 0.5 MPa while the 63 mm bore reaches 1558 N, so 40 mm sits comfortably for medium clamping and positioning work. With 160 mm of stroke, brace the 16 mm rod against side loads using external guides. The trim screw is an extend-direction stop, not a holding brake - dropped air means the rod can still move. Pick FA or LB mounting to suit the machine frame.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-50S FAQ
Push 628 N and pull 528 N at 0.5 MPa; push 880 N and pull 739 N at 0.7 MPa; theoretical peak 128.1 kgf at 1.0 MPa. Port size 1/8 in, rod thread M12x1.25, 16 mm rod, and the extend stroke adjusts anywhere from 110 to 160 mm.
No. Every MA-series cylinder carries a piston magnet as standard, so CMSG, DMSG or EMSG switches snap onto the stainless barrel at any point along the 160 mm stroke.
