About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X175-CA
The AirTAC MBL40X175-CA is a compact double-acting aluminum mini round cylinder engineered to deliver 628 N of push force and 528 N of pull force at 0.5 MPa. The 175 mm stroke provides ample travel for mid-range actuation tasks. A defining trait of this SKU is the CA pivot (clevis) back cover, which allows the cylinder body to swing on a pin, making it highly effective for driving loads through arcs or accommodating angular misalignment.
Unlike tie-rod bodies that can be unbolted for maintenance, this unit utilizes a riveted rolling-packed aluminum barrel where the covers are crimped permanently to the tube, ensuring a lightweight, space-saving footprint. The carbon-steel piston rod features a 20 um hard-chrome plating to resist wear and corrosion. Because this specific configuration lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch. End-of-stroke deceleration is handled by a fixed rubber bumper, which softens impact but does not lock the rod in place if air pressure is lost.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X175-CA Is Used
Textile Loom Guide Arm
Swings a yarn guide arm through an arc using the CA pivot back cover, applying 628 N of push force to tension and shift weaving patterns.
Package Sorting Diverter
Pivots a diverter arm on a packaging line to route parcels, utilizing the 175 mm stroke to clear the belt before retracting.
Feeder Hopper Gate
Actuates an angular discharge gate on an automated livestock feeder, where the clevis mount accommodates the swing of the heavy hopper door.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X175-CA the Right Cylinder?
If your application requires less force, stepping down to the 32 mm bore yields 402 N of push at 0.5 MPa, whereas moving up to the 50 mm bore provides 981 N. For tasks needing end-of-stroke speed control on heavier masses, the MBLC variant offers an adjustable air cushion instead of the standard fixed rubber bumper. If you need spring-return or push-only action, consider the MSBL or MTBL single-acting lines. Keep in mind that a plain MBL cylinder drifts or drops when air is exhausted or valve pressure is lost; the bumper only softens impact and will not hold a load. For secure positioning without live pressure, utilize an external rod lock or a pilot-operated check valve.
With a 175 mm stroke on a Ø16 mm rod, the unsupported length is significant. Long mini rods have low side-load tolerance and are prone to bending under off-axis forces. The CA pivot back cover on this model helps mitigate angular stresses, but you should still employ an external guide rail or consider the MBLD double-rod anti-rotation type for heavy radial loads. This SKU uses a G1/4 port with PT tapered threading.
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 MBL Aluminum Alloy Mini Cylinder MBL40X175-CA 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, the push force increases to 880 N, with a maximum theoretical force of 128 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No. Because this specific SKU lacks the -S suffix, it does not have a built-in magnet and cannot accommodate CMSG, DMSG, or EMSG sensor switches. You would need to specify an MBL40X175S-CA model to enable sensor mounting.
