5. Unique FAQ
Q1: Is this bucket cylinder interchangeable with PC300-7 original bucket cylinder?
A: No, mounting center distance and internal stroke differ between PC300-7 and PC300-8, so cross installation is not feasible.
Q2: Do you supply the connecting pins together with cylinder package?
A: Standard package excludes pins, but we can supply matched size pins at extra favorable cost upon buyer’s request.
Q3: What causes most early seal damage for this bucket cylinder?
A: Mixed inferior hydraulic oil and rock grit entering rod surface are top reasons; regular rod cleaning helps extend seal lifespan greatly.
Q4: Can customer inspect goods before shipment for bulk orders?
A: Yes, we support factory inspection or third-party inspection before bulk order dispatch as agreed.
Q5: If I receive damaged cylinder during transit, how to solve?
