PUTZMEISTER SOURCING
SRA-110-360-CO-RF-SH-N Rotary Actuator
The SRA-110-360-CO-RF-SH-N is a compact 360-degree, rear-flange (RF) helical rotary actuator in the SRA-110 class, rated at 3000 psi (about 207 bar) and recorded in connection with Putzmeister equipment. On the reference nameplate this 360-degree build carries the factory parts number RA1101K02-0. HM provides technical selection and sourcing / alternative-supply support and confirms the exact configuration, mounting, shaft and ports against your actuator nameplate before quotation; we do not represent the offered unit as an original Putzmeister part or promise stock, lead time or a pre-verified interchangeable unit from the code alone.

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 |
| 360 | Rotation | Standard 360° rotation |
| 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 |

What the 360° sweep changes on this build
A full-turn build: the output sweeps a complete revolution. The hose loop and its clamping have to survive the whole sweep, which is why a full-turn unit is checked as a hose-routing question as well as a torque question.
- Check the hose loop clears the housing through the full revolution, not just at the rest position.
- Confirm the duty actually needs a complete turn — a half-turn build of the same size is the usual choice where it does not.
- Rotation stops, if the machine has them, sit outside the actuator and still have to be checked.
When this sweep is the right build
- Duties that genuinely index through a full revolution — rod handling, turret positioning, continuous swing.
- Linkages where the return path is part of the cycle rather than a reversal of the same half turn.
- Machines already built around a full-turn hose loop, where a half-turn unit would leave the routing over-travelled.
Confirming the sweep on the machine
- Turn the linkage through a full revolution by hand and watch the hose loop — a unit that binds at three quarters of a turn is a routing problem, not a torque problem.
- Check whether the machine has an external rotation stop; if it does, the sweep on the tag is not the limit the linkage actually uses.
How the sweep sits in the order code
The sweep is the fifth segment of the code. Going to the half-turn build of the same size changes that segment and the internal stop tube; flange, shaft and valve stay as they are. Where a machine only needs two positions, the half-turn build is the shorter hose route and the smaller envelope.
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.

| Cross reference | This is a model-code sourcing entry for an SRA-110 class 360-degree rear-flange unit; the reference nameplate shows factory parts number RA1101K02-0. The same SRA-110 class is used by several equipment makers with different port, valve and seal codes (the 240-degree build carries a different parts number), so the full suffix is confirmed against your nameplate and drawing before any alternative is recommended. |
| Further data | Torque, pressure, port and mounting dimensions are shared with the engineering drawing on request. |

Send us your original model number, part number or machine details and we confirm the matching configuration, specifications and compatibility, then quote. The exact ordering code — rotation, output and valve arrangement — is confirmed against your unit and is not published online.

Questions
Frequently asked questions
What does the SRA-110-360-CO-RF-SH-N replace?+
It is the original Putzmeister model code for a helical hydraulic rotary actuator providing 360° 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 RA1101K02-0. 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 does the code SRA-110-360-CO-RF-SH-N mean?+
It encodes the SRA family and 110 size, 360-degree rotation, port/valve segment (CO), rear-flange mounting (RF), shaft/cover and seal/standard segments. The exact build must be read from the full nameplate code because several variants share the SRA-110 base.
What is the parts number RA1101K02-0 on the tag?+
RA1101K02-0 is the factory parts number stamped on the reference 360-degree SRA-110 nameplate. It is useful for confirming the exact build and rotation, but it is the actuator maker’s parts number rather than a Putzmeister machine number; quote either the full model code or this parts number together with a nameplate photo.
Can HM supply the Putzmeister SRA-110-360-CO-RF-SH-N?+
We offer selection and sourcing / alternative-supply support for this 360-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 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.
