About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X200SCA
The AirTAC MBLC40X200SCA is a double-acting aluminum mini cylinder with a 40mm bore and 200mm stroke, delivering 628N push and 528N pull force at 0.5 MPa. The CA pivot clevis back cover swings on a pin to accommodate arcing loads, while the integrated -S magnet enables position detection via CMSG reed or DMSG and EMSG solid-state switches. It features a G1/4 port and an M12x1.25 rod-end thread.
Unlike the base MBL fixed-bumper line, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. You tune the needle to smoothly decelerate the piston near stroke extremes, absorbing kinetic energy to protect the end covers on faster or heavier moves. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, and the heterogeneous two-way grease-retaining piston seal works with the 20 um hard-chrome carbon-steel rod to maintain lubrication over high-frequency cycles.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X200SCA Is Used
Textile Loom Let-Off
Drives the tensioning arm on a weaving loom, using the 628N push force to maintain fabric tension while the CA clevis absorbs the angular pivot of the let-off mechanism.
Package Divert Gate
Actuates a pivoting routing gate on a 75-meter-per-minute logistics conveyor, where the adjustable air cushion prevents the 200mm stroke from slamming at high cycling frequencies.
Pallet Strapping Head
Positions the strapping feed mechanism over varying pallet heights, using the -S magnet and a DMSG electronic switch to confirm the extended position before the band seals.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X200SCA the Right Cylinder?
For a 40mm bore providing 628N of push force at 0.5 MPa, stepping down to the 32mm bore yields 402N, while stepping up to the 50mm bore provides 981N. Choose this MBLC model over the standard MBL when your cycle speeds are high or the moved mass is substantial enough that a fixed rubber bumper cannot adequately absorb the impact. The adjustable air cushion only decelerates the rod near the ends; it is not a locking brake, so the rod will drift if air is lost or the valve centers.
At 200mm of stroke, the 16mm rod is subject to bending under lateral stress. For this length, ensure side loads are minimized using an external guide rail, or rely on the CA pivot clevis to self-align the angular movement. The replacement match for this SKU is a 40mm bore, 200mm stroke, PT thread, CA clevis back cover, with the -S magnet fitted.

- ✓ 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 MBLC40X200SCA FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628N push and 528N pull force. At 0.7 MPa, it provides 880N push, with a maximum theoretical output of 128 kgf at 1.0 MPa. It uses a G1/4 port and an M12x1.25 rod-end thread.
The screw-tunable pneumatic cushion at both stroke ends decelerates the piston smoothly to prevent end-cover impact on heavy or fast moves, but it is not a load lock. The CA back cover is a pivot clevis that swings on a pin, designed specifically to handle arcing and angular loads without binding.
