Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X175-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X175-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 175mm stroke, M5×0.8 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 MACJ16X175-20S
With a 20 mm trim band on the extend stroke, this 16 mm bore, 175 mm stroke MACJ lets maintenance teams retune travel without swapping cylinders. Push is 100.5 N at 0.5 MPa and 140.7 N at 0.7 MPa; retract delivers 86.4 N. Budget roughly 60 N for real work and you keep a wide margin on light clamping and gating duty.
The body is a riveted round tube of stainless steel with a hard-chrome plated rod - a construction that stands up to splashes, coolant mist and outdoor weather where painted minis rust. Variable air cushions at both ends plus a 30-800 mm/s speed band let you tune the cycle quietly, and the magnet ships inside, ready for CMSG / DMSG / EMSG switches.

Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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 MACJ16X175-20S Is Used
Small bracket staking
Holding thin aluminium brackets against a staking die on an electronics assembly cell, where 60 N-class working force and a tunable stroke window fit the fixture.
Parcel kick-off diverter
Kicking small e-commerce parcels off a mini roller conveyor; the dual cushion protects the frame when the 100.5 N push arrives at the stop.
Sampler valve actuator
Switching a compact sample valve in a water treatment skid, leaning on the stainless body and chrome rod against constant humidity.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X175-20S the Right Cylinder?
Compare outputs side by side: 100.5 N at 0.5 MPa here, 157 N for the 20 mm bore, and 245.3 N if you step to 25 mm. Mounting choices run to FA flange, LB foot and I or Y rod knuckles; ports are M5x0.8 on this bore. The 20 mm window only shortens the extend stroke - it will not lengthen travel past 175 mm, and it is no substitute for a load-holding brake if the air drops.
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 MACJ16X175-20S FAQ
Double-acting output: 100.5 N push / 86.4 N pull at 0.5 MPa, 140.7 N push / 120.9 N pull at 0.7 MPa, and a theoretical 20.5 kgf maximum at 1.0 MPa. The 16 mm bore uses an M5x0.8 port, M6x1.0 male rod thread and 6 mm rod. The extend stroke adjusts across a 20 mm band, with variable cushions at both ends and 0.15-1.0 MPa (22-145 psi) supply.
The stop screw is a mechanical end stop that shortens the extend stroke within the ordered 20 mm window. It sets position, not holding force - if air pressure is lost the piston can still be pushed off the stop, so add a separate brake or clamp where a load must be held.
