How to find the right Mechanical Shock Absorbers AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Mechanical Shock Absorbers
- Energy per cycle
- Calculate kinetic energy plus propelling-force energy over the stroke; the absorber's rated energy per cycle must exceed it with margin. Undersized units bottom out, which transfers full impact to the frame and destroys the seals.
- Energy per hour
- Energy per cycle multiplied by cycles per hour must stay under the rated hourly energy. Heat build-up limits fast-cycling machines even when single-impact energy is fine.
- Effective weight and impact velocity
- Size against the catalogue's effective-weight range at your actual impact speed, not against moving mass alone. Orifice sizing is tuned to a weight and velocity band, so the wrong band gives either a hard stop or rebound.
- Adjustable vs self-compensating
- Choose adjustable units when the load or speed is unknown or varies a lot. Choose self-compensating units for a known, steady range. Self-compensating units are set-and-forget only inside their design window.
- Stroke and positive stop
- Use a stop collar or external stop so the absorber never acts as the end stop. Bottoming on the internal end damages the piston and tube.
- Side load and thread
- Match the thread size and pitch to the mounting. Keep side load within the rated angle, or use an angled-impact cap. Off-axis impact wears the rod bearing and causes leaks.
Brands that matter
- ACE Controls: Wide industrial range with detailed sizing data, including adjustable and self-compensating miniature units.
- ITT Enidine: Established industrial and heavy-duty absorber line with good sizing documentation.
- SMC: Compact pneumatic-automation absorbers, common on actuator end stops.
- Misumi: Configurable stock units convenient for machine builders.
What to avoid
- Unbranded absorbers with no published energy-per-cycle or effective-weight ratings
- Using the absorber as the mechanical end stop
- Choosing by thread size alone without an energy calculation
- Mounting where coolant or chips hit the rod without a boot or cover
Questions
Is a gas spring the same as a shock absorber?
No. A gas spring stores and returns energy, while a hydraulic shock absorber dissipates energy as heat to stop a load without rebound.
