SDA standard configuration dimensions; male rod-end dimensions are on the SDA standard sheet

Helpful for Model Matching:

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

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

Fits when

A compact cylinder is needed where installation height is limited
The required motion, bore, stroke, and rod-end arrangement are known

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
For SDAT and SDAW, stroke 1 + stroke 2 must not exceed the applicable stroke-table value.

Read the model code

If the label is incomplete, send the readable parts together with a photo.

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.

Matching Questions

Which SDA details should be included in an RFQ?

Send the full code where available, plus bore, stroke, mounting or rod-end details and the required sensor arrangement. A photo or drawing helps confirm variants before quotation.

Which cylinder configurations belong to the SDA family?

No. This is the SDA Series family page. SDA is the standard double-acting variant; SSA, STA, SDAD, SDAJ, SDAT and SDAW have different motion or structural configurations. Use the family code before comparing dimensions.
