This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X175CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X175CA in place of this model. The MBL replacement upgrades to a riveted rolling-packed body and the current CMSG / DMSG / EMSG sensor switches (the MAL used CS1-M / DS1-M).
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X175CA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL40X175CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 175mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL40X175CA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X175CA
The AirTAC B01-MAL40X175CA is a discontinued double-acting aluminum mini round cylinder. The leading B01- prefix marks this as an application-dedicated, customer-specified variant of the standard MAL40X175CA, meaning it is mechanically identical to the base model. It delivers 628 N push and 528 N pull at 0.5 MPa, utilizing a 16 mm carbon-steel rod with 20 um hard chrome plating guided by a self-lubricating front-cover bearing. AirTAC replaced this legacy unit with the MBL40X175CA, a drop-in alternative retaining the exact 40 mm bore, 175 mm stroke, G1/4 port, and CA pivot mounting.
This SKU features a CA pivot (clevis) back cover designed to swing on a pin, accommodating arcing loads. Unlike the legacy MAL which uses threaded front and back covers, the modern MBL replacement utilizes a riveted rolling-packed body for structural rigidity. Because this specific configuration lacks the -S magnet option, it cannot accept a position sensor. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL40X175CA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The B01-MBL40X175CA produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X175CA Is Used
Packaging Flap Folder
Drives the mechanical arm on a corrugated box erector, using the 628 N push force to fold heavy cardboard flaps while the CA pivot absorbs linkage misalignment.
Pallet Divert Gate
Actuates a routing gate on a logistics conveyor, where the 175 mm stroke pushes cartons onto a side track and the clevis mount handles the arcing load.
Bottle Sorting Chute
Pushes glass beverage containers into a single-file lane on a filling line, relying on the self-lubricating bearing to maintain smooth operation in humid environments.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X175CA with B01-MBL40X175CA
To replace the B01-MAL40X175CA, order the MBL40X175CA. Confirm your 175 mm stroke, G1/4 port, PT thread form, and CA clevis mount to ensure a seamless drop-in fit. If your mechanism requires end-of-stroke cushioning, the fixed rubber bumper on this legacy unit cannot be adjusted; you should instead look at the current MBLC40X175CA which offers an adjustable air cushion. If you need position sensing, this no-magnet SKU cannot support it, and the modern MBL -S variant requires the newer CMSG, DMSG, or EMSG switches rather than the older CS1-M or DS1-M sensors.
When sizing, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa, while stepping up is not an option as 40 mm is the largest MAL mini round bore. Since the 175 mm stroke exceeds 300 mm, the 16 mm rod has low side-load tolerance; rely on the CA pivot to absorb alignment shifts or add an external guide to prevent rod bending. Note that a plain cylinder drifts when air is lost—the bumper softens impact but does not lock the load, so add a rod lock for vertical holding.
Upgrade checklist
- ✓ Order the B01-MBL40X175CA (same bore/stroke/force)
- ✓ Same G1/4 port and mounting accessories
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ Need a cushion? use MBLC (adjustable air cushion)
- ✓ Confirm back cover (CA / U) and thread (PT/NPT/G)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Front/rear covers are threaded — not intended for field disassembly.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U / CM).
- check For new builds, specify the B01-MBL40X175CA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X175CA FAQ
Yes, the B01-MAL40X175CA is discontinued. The exact drop-in replacement is the MBL40X175CA, which matches the 40 mm bore, 175 mm stroke, G1/4 port, and CA pivot mount. The B01- prefix simply denotes an application-dedicated build of the base MAL40X175CA, so the physical specs remain identical.
At 0.5 MPa it provides 628 N push and 528 N pull; at 0.7 MPa it provides 880 N push, with a theoretical maximum of 128 kgf at 1.0 MPa. It cannot hold position if air is lost, as the fixed rubber bumper only softens the end of stroke and does not act as a lock.
