Avoid a wrong match
- SDA, SSA, and STA can look similar but use different motion types
- Compare bore and stroke with the installed cylinder, not the body shape alone
- Check the sensor groove and rod-end thread where they are needed
Choose the SDA family first
A similar body does not guarantee the same function. Confirm the function and interface first, then compare size and installed dimensions.

SDA 20 × 30 S B [PT]SDAFamily
Double-acting compact cylinder. Use a different family code where the motion differs.
20Bore
Cylinder bore in mm. Published SDA-family bores run from 12 to 100 mm, depending on variant.
30Stroke
Required travel in mm. Compare it with the installed cylinder or drawing.
SMagnet
S denotes a magnetic option; check the sensor requirement and groove arrangement.
BRod end
B denotes a male thread; blank denotes a female thread in the published code guide.
[PT]Thread standard
The published code guide indicates PT when this position is left blank. Compare the installed thread for replacement work.
About SDA
Compact cylinders for limited installation space. SDA, SSA, STA, SDAD, SDAJ, SDAT and SDAW belong to one family but are not interchangeable; the family code identifies the configuration.
Product matching reference
Compare the photo, drawing, and measurable details first
Identify from the photo
- Full SDA-family model code or label
- Bore and required stroke
- Rod-end, mounting and installed clearance
- Whether a magnetic switch or sensor groove is required
Drawing reference
- Use the drawing for the matching SDA-family configuration
- Compare bore, stroke, mounting holes, rod-end thread, and installed clearance
- For replacement work, include the full drawing with the RFQ when fit is critical
