About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X160U
The AirTAC MBLC40X160U is a double-acting aluminum mini cylinder with a 40 mm bore and 160 mm stroke. It generates 628 N of push force and 528 N of pull force at 0.5 MPa. Unlike the base fixed-bumper version, this MBLC variant features a screw-adjustable pneumatic cushion at both ends. You tune the needle to decelerate the piston smoothly near each stroke end, cutting impact, noise, and vibration on faster or heavier moves. It is not a load lock or brake—it only cushions near the travel limits.
This 160 mm stroke suits mid-length traversing or lifting tasks that need controlled stops. The compact body uses a riveted rolling-packed aluminum barrel for a light, space-saving profile rather than a bulky rebuildable tie-rod design. Inside, a heterogeneous two-way grease-retaining piston seal pairs with a 20 µm hard-chrome plated carbon-steel rod. The U flat-end back cover provides a rigid default rear mounting face. Note that this specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensing.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X160U Is Used
Carton Erector Feed
Pushes corrugated blanks into a forming pocket with 628 N at 0.5 MPa, using the tunable cushion to prevent hard end-cover impacts during continuous 160 mm cycling.
PCB Shuttle Transfer
Moves populated boards between test stations on a 160 mm track, where the adjustable air end-cushioning protects delicate solder joints from sudden deceleration shocks.
Tray Indexing Gate
Actuates a 160 mm gating mechanism for component trays, relying on the cushion needle to smooth the stroke end and reduce mechanical vibration on the frame.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X160U the Right Cylinder?
Stepping down to the 32 mm bore yields 402 N of push force at 0.5 MPa, which may suffice for lighter payloads. Stepping up to the 50 mm bore provides 981 N of push force at 0.5 MPa for heavier mass. Choose this MBLC over the fixed-bumper MBL when your cycle speeds are high or the moved mass is heavy enough that a rubber bumper would fail. Because this is a 160 mm stroke, watch rod bending: the 16 mm rod has low side-load tolerance, so use an external guide or pivot mount for arcing loads. A plain double-acting cylinder does not hold position if air is lost or the valve centers—the rod drifts. For holding without live air, add an external rod lock or pilot-operated check valve. Replacement match: 40 mm bore, 160 mm stroke, G1/4 port, PT thread, U flat-end back cover, no magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X160U FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, it delivers 880 N push and 739 N pull. The maximum theoretical force is 128 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
The MBLC40X160U has a screw-adjustable pneumatic cushion needle at both ends. You tune the needle to match your load and speed, trapping a small air pocket to decelerate the piston smoothly near the stroke end. This protects the end covers from impact, unlike the base MBL which relies on a fixed rubber bumper.
