💡 What causes a single acting air cylinder to lose holding power over time?
Seal wear and internal leakage often affect performance, so checking these factors keeps your setup reliable. Ensure you inspect these common failure points to maintain proper operation.
- Worn piston seals allow compressed air to bypass the rod during extension cycles.
- Port leaks reduce system pressure so the tool cannot generate full rated push force.
- External damage to the rod surface creates micro paths that compromise seal contact.
- Incorrect supply pressure prevents the spring return mechanism from resetting fully.
