Brand replacement research

SMC RB shock absorber replacement options — RB with cap

The SMC RB series pages below use official catalog energy, stroke, frequency, thrust and thread data. The EKD candidate is a performance shortlist, not a drop-in mounting claim.

1 referenced models in this series. Model-number relationships are recommendations only; final selection is based on actual operating conditions.

Matched or capacity-qualified
Energy per cycle · Body thread
Different or confirmation-required
Hourly energy (derived; not a thermal rating) · Stroke · Impact velocity · Allowable drive thrust · Impact / reaction force

Recommended by model and published ratings. Final selection must follow actual operating conditions, mounting and application review.

How EKD candidates are shortlisted

Published energy per cycle, hourly duty, stroke, velocity and force are checked first. Mounting thread, total length, stop geometry and environmental requirements are then treated as separate confirmation items.

What to send for a final check

Send the full model code, nameplate or drawing, moving mass, impact velocity, drive force, cycles per hour, installation position and temperature. A model-family similarity alone is not a replacement approval.

Continue the assessment

A model-number recommendation is a shortlist. EKD confirms the actual operating and installation conditions before ordering.
