Does anyone know how many cycles (extend / retract) that a hydraulic cylinder should be able to do before needing repair?
The specifics for the cylinder are that there is minimal (almost none) low frequency and low amplitude pulsing of pressure. The cylinder will cycle once every 5 minutes for 20 hours each day, and pressure hold time will be 2 minutes each cycle. The weight against the cylinder produces very little side loading due to the weight riding on linear sleeve bearings. The environment is humid with temperatures ranging from 40° F to 90° F and it is approximately as clean as a typical basement utility room.
Cylinder bore: 5 inches.
Cylinder stroke: 60 inches
Cylinder press: 2200 PSI
Oil temperature: Will not exceed 100° F
Seals etc.: Assume high quality
I have searched many pages and spent many hours trying to get any kind of estimate or range, or guess. So if anyone has any knowledge of this, please respond.
