Festo YSR-20-25-C / 34574 replacement option: EN36x50 comparison

Compare published Festo YSR-20-25-C / 34574 ratings with the EKD EN36x50 candidate, including energy, stroke, mounting differences and inquiry checks.

EN36x50 can be evaluated as a replacement option because it meets the compared energy, hourly-duty and stroke thresholds. Mounting, velocity, force, cycle and machine conditions must still be confirmed.

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.

Energy per cycle60 J (Nm)310 Nm/CMeets reported rating

A catalog rating comparison only; effective mass, drive force and deceleration remain application checks.

Energy per hour92,000 J/h111,000 Nm/hMeets reported rating

Confirm the actual cycle rate and thermal conditions.

Stroke25 mm50 mmMeets reported rating

Confirm usable travel, stop position and reset clearance.

Body threadM26 x 1.5M36 x 1.5Different — confirm

Different threads require a mounting change or adapter review.

Nominal total length104 mm207 mmDifferent — confirm

Check the drawing reference points, installed envelope and rod-end geometry.

Impact velocity0.05–3 m/s0.08–18 m/sInquiry confirmation required

Compare the real operating point, not only the published maximum.

Published force limit3,000 N11,120 N max impact forceInquiry confirmation required

The manufacturers may define force ratings differently; verify the machine limit and deceleration curve.

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.
