SMC RB2725 replacement option: EN36x25 comparison
Compare published SMC RB2725 ratings with the EKD EN36x25 candidate and confirm the actual application conditions.

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 | SMC RB2725 | EKD EN36x25 | Assessment |
|---|---|---|---|
| Energy per cycle | 147 J (Nm) | 160 Nm/C | Meets reported rating A catalog rating comparison only; effective mass, drive force and deceleration remain application checks. |
| Hourly energy (derived; not a thermal rating) | 88,200 J/h (calculated) | 91,000 Nm/h | Inquiry confirmation required Calculated as impact energy × maximum frequency in cycles/min × 60. Separate maxima need not be permissible together; this is not an independently published hourly thermal rating. Confirm actual duty and thermal conditions. |
| Stroke | 25 mm | 25 mm | Matched reported value Confirm usable travel, stop position and reset clearance. |
| Body thread | M27 x 1.5 | M36 x 1.5 | Different — confirm Different threads require a mounting change or adapter review. |
| Impact velocity | 0.05–5.0 m/s | 0.08–16 m/s | Inquiry confirmation required Compare the real operating point, not only the published maximum. |
| Allowable drive thrust | 2,942 N maximum allowable thrust | Not established in this comparison | Inquiry confirmation required SMC allowable thrust is not an impact/reaction-force rating. Confirm the EKD allowable drive thrust from the exact model record and application review. |
| Impact / reaction force | Not established in this comparison | 11,120 N max impact force | Inquiry confirmation required The EKD published impact-force value cannot be compared with SMC allowable drive thrust. Obtain reaction-force behavior for the actual stopping duty. |
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.
