ACE Controls MA3350 replacement option: EK42x50 comparison
Compare published ACE Controls MA3350 ratings with the EKD EK42x50 candidate and confirm the actual application conditions.
Browse ACE Controls MA / MA-M modelsCandidate requires mounting changes or dimensional review Final selection requires operating data and a drawing review.
Published parameter comparison
The table compares published catalog values. A higher rating can identify a performance candidate, but it does not remove mounting, force, reset, environment or application checks.
| Parameter | ACE Controls MA3350 | EKD EK42x50 | Assessment |
|---|---|---|---|
| Energy per cycle | 429.3 J (Nm) | 850 Nm/C | Meets reported rating A catalog rating comparison only; effective mass, drive force and deceleration remain application checks. |
| Energy per hour | 85,870 J/h | 167,000 Nm/h | Meets reported rating Confirm the actual cycle rate and thermal conditions. |
| Stroke | 48.6 mm | 50 mm | Different — confirm Different dimension — stop position, mounting geometry and installation review required. A larger value does not establish interchangeability. |
| Body thread | 1-1/4-12 UNF | M42 x 1.5 | Different — confirm Different threads require a mounting change or adapter review. |
| Nominal total length | 189 mm | 195 mm | Different — confirm Check the drawing reference points, installed envelope and rod-end geometry. |
| Impact velocity | MA range: 0.15–5.03 m/s | 0.3–3.5 m/s | Inquiry confirmation required Compare the real operating point, not only the published maximum. |
What must be matched and confirmed
- Actual moving mass, impact velocity and drive force
- Mounting thread, stop geometry and available envelope
- Cycle rate, return time and permissible deceleration
- Temperature, corrosion, alignment and side loading
Continue with EKD review
Open the EKD candidate, then use the matching tool or send the original nameplate, drawing and application data. EKD will confirm the remaining differences before ordering.
