Kailing mini and compact pneumatic cylinders cover round-body MAL and DSNU cylinders plus square compact SDA and CQ2 families. Use this page 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.

Buyer-facing RFQ fields
| 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.
