Kailing mini and compact pneumatic cylinders cover round-body MAL and DSNU cylinders plus square compact SDA and CQ2 families. Check the product information to confirm bore, stroke, action type, pressure, speed, port and magnetic sensor requirements before RFQ.
- 01 When to use MAL and DSNU
Use MAL round-body mini cylinders for compact pneumatic motion where a lightweight aluminium cylinder is preferred. Use DSNU when the machine design calls for an ISO6432-style small-bore cylinder.
- 02 When to use SDA and CQ2
Use SDA or CQ2 compact cylinders when the installation space is short and a compact block-style body is easier to mount than a round mini cylinder.
SDA - 20 X 30 - S - MAL: aluminium alloy mini cylinder
- DSNU: ISO6432 standard cylinder
- SDA: compact cylinder, double acting or single acting variants
- CQ2: compact thin cylinder
- MAL catalog bore: 16-40mm
- SDA and CQ2 catalog bore: 12-100mm
- DSNU catalog bore: 8-25mm
- Specify exact stroke in mm
- Catalog gives stroke ranges by bore and magnetic option
- S: with magnet on MAL/SDA examples
- A: with magnet on DSNU example
- Blank: without magnet
- MAL: basic, FA, LB, SDB, CA, CM, U by catalog option
- CQ2: through-hole standard or internal-thread mounting option
When to use MAL and DSNU
Use MAL round-body mini cylinders for compact pneumatic motion where a lightweight aluminium cylinder is preferred. Use DSNU when the machine design calls for an ISO6432-style small-bore cylinder.
When to use SDA and CQ2
Use SDA or CQ2 compact cylinders when the installation space is short and a compact block-style body is easier to mount than a round mini cylinder.
Selection notes
Confirm bore, stroke, action type, magnet requirement, mounting style, port size, operating pressure, operating speed and quantity before quotation.

Quotation details
| Field | Why it matters |
|---|---|
| Series | MAL, DSNU, SDA and CQ2 use different bodies, mounting and dimensional tables |
| Bore and stroke | These define cylinder force and travel and must match the machine design |
| Action | Confirm double acting, single acting push-out or single acting pull-in |
| Magnet | Required when the machine needs magnetic switch position feedback |
| Mounting | Select basic, flange, foot, clevis, through-hole or threaded mounting by series |
| Port thread | Confirm M5, G1/8, G1/4 or G3/8 according to tubing and manifold layout |
Frequently Asked Questions
- FAQ Can Kailing quote a compact cylinder without the exact model number?
Yes. Send bore, stroke, mounting style, action type, magnet requirement, port size, working pressure and photos or drawings if replacing an existing cylinder. - FAQ Which compact cylinder families include single acting options?
The catalog lists single acting push-out or pull-in options for SDA/SSA/STA and single acting spring return or extend options for CQ2. - FAQ What is the main difference between MAL and SDA?
MAL is a round-body aluminium mini cylinder, while SDA is a thin compact cylinder for installations where a shorter block-style body is preferred.
