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 MA4550M | EKD EK42x50 | Assessment |
|---|---|---|---|
| Energy per cycle | 850 J (Nm) | 850 Nm/C | Matched reported value A catalog rating comparison only; effective mass, drive force and deceleration remain application checks. |
| Energy per hour | 112,985 J/h | 167,000 Nm/h | Meets reported rating Confirm the actual cycle rate and thermal conditions. |
| Stroke | 48.5 mm | 50 mm | Different — confirm Different dimension — stop position, mounting geometry and installation review required. A larger value does not establish interchangeability. |
| Body thread | M45 x 1.5 | M42 x 1.5 | Different — confirm Different threads require a mounting change or adapter review. |
| Nominal total length | 195.3 mm | 195 mm | Different — confirm Different dimension — stop position, mounting geometry and installation review required. A larger value does not establish interchangeability. |
| 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.
