PUTZMEISTER SOURCING
SRA-110-240-CO-RF-SH-N Rotary Actuator
The SRA-110-240-CO-RF-SH-N is the 240-degree variant of the compact SRA-110 class rear-flange (RF) helical rotary actuator, rated at 3000 psi (about 207 bar) and recorded in connection with Putzmeister equipment. On the reference nameplate the 240-degree build carries the factory parts number RA1101K03-0. HM provides technical selection and sourcing / alternative-supply support and confirms the rotation angle, mounting, shaft and ports against your nameplate before quotation; the offered unit is not represented as an original Putzmeister part.

Code anatomy
What each part of this code means
Every segment below is read from the manufacturer’s published ordering key. Where a segment is not published, we say so instead of guessing — those are the ones to confirm from the tag or the drawing before ordering.

Sungji SRA / SRB / SRS range
| Segment | Field | What it tells you |
|---|---|---|
| SRA | Series | SRA series — body and mounting family |
| 110 | Size | Size 110 — sets the displacement and the torque class |
| 240 | Rotation | Non-standard rotation angle (240°) — special build |
| CO | Valve | No valve |
| RF | Mounting | Rear flange |
| SH | Shaft end | Shaft end code — exact profile confirmed against the drawing |
| N | Seals | Standard seal package |
Full ordering key and how to read a tag: identifying a rotary actuator.
What the 240° sweep changes on this build
A non-standard sweep: 240° sits outside the usual 180° / 360° range, which means the stop tube was cut for that angle. A standard-angle unit will not reproduce it, and the stop positions have to be read off the drawing rather than assumed.
- Read the stop positions off the mounting drawing before ordering — do not infer them from the code alone.
- Ask why the original used this sweep; a non-standard angle usually answers a linkage constraint that a standard unit will not fit.
- Confirm the sweep on the unit tag matches the code, since special builds are sometimes re-stopped in service.
When this sweep is the right build
- Linkages whose geometry was designed around this exact sweep — the stop positions usually answer a clearance or interference constraint.
- Rebuild work where the surrounding mechanism has to stay unchanged, so the sweep cannot be normalised to 180° or 360°.
- OEM builds where the sweep was specified by the machine maker rather than chosen from a catalogue.
Confirming the sweep on the machine
- Measure the swing between the mechanical end stops on the machine, not between the positions the linkage happens to use.
- Compare the measured swing with the code on the tag; special builds are sometimes re-stopped in service.
How the sweep sits in the order code
The sweep is the fifth segment of the code, and here it carries a value outside the standard range. That value is a build instruction, not a selection from a list: it has to travel with the enquiry together with the stop positions, because the stop tube is cut for it.
Where these two builds get mixed up
- A full-turn unit is sometimes quoted where the linkage only swings half a turn, which over-travels the hose loop for no benefit.
- If a full-turn unit will not pass a quarter or half turn under load, the cause is usually hose routing or an external stop, not the actuator.
We do not publish a conversion table between sweeps. If the sweep on your unit differs from the code above, send the tag and the mounting drawing and the build is confirmed against them.

| Cross reference | This is a model-code sourcing entry for the SRA-110 class 240-degree rear-flange unit; the reference nameplate shows factory parts number RA1101K03-0. The 240-degree and 360-degree builds share the same SRA-110 frame but differ in rotation/end-stop geometry and carry different parts numbers (the 360-degree build is RA1101K02-0), so they are not interchangeable; confirm the angle and full suffix against your nameplate. |
| Further data | Torque, pressure, port and mounting dimensions are shared with the engineering drawing on request. |

Questions
Frequently asked questions
What does the SRA-110-240-CO-RF-SH-N replace?+
It is the original Putzmeister model code for a helical hydraulic rotary actuator providing 240° rotation. HM provides sourcing and alternative-supply support for this reference; it is not assumed to be an original Putzmeister part or a pre-verified interchangeable unit, and the configuration is confirmed against your actuator nameplate and drawing before we quote. It is listed by Putzmeister under part number RA1101K03-0. HM can source or arrange alternative supply for this reference; mounting dimensions, shaft, ports and the exact configuration are checked against your unit and drawing before any alternative is recommended.
What is the difference between SRA-110-240 and SRA-110-360?+
They use the same SRA-110 frame and rear-flange mounting but differ in total rotation: 240 degrees versus 360 degrees, which changes the internal end-stop geometry and the parts number (RA1101K03-0 for the 240-degree build and RA1101K02-0 for the 360-degree build). Read the rotation from your tag; the two units cannot simply be swapped.
Can HM supply the SRA-110-240-CO-RF-SH-N?+
We offer selection and sourcing / alternative-supply support for this 240-degree rear-flange unit. We do not claim a verified drop-in or that the offered unit is an original Putzmeister part; send the nameplate and a mounting drawing and we confirm the angle, mounting, shaft, ports and seal package before quoting.
Why is the exact HM model and price not shown?+
We confirm the HM model per inquiry after verifying the interface and operating parameters with you. This avoids shipping a part that looks right by model name but differs in mounting or rotation. Price is provided with that confirmed quote.
