4. FAQ
Q: Where is this piston seal ring installed?
A: It fits into a dedicated groove on the outer surface of the piston, inside the hydraulic cylinder. When installed, it sits between the piston and the cylinder bore, creating the main dynamic seal.
Q: What if the seal ring’s dimensions are slightly off?
A: If the ring is too small, it won’t press hard enough against the bore, causing fluid to leak past and reducing the cylinder’s power. If it’s too large, forcing it into the groove will permanently deform it, leading to excessive friction, heat, and early failure.
Q: What happens if the seal ring is installed the wrong way around?
A: The seal’s profile is designed to work in a specific direction. Installing it backwards disrupts the contact geometry, preventing it from building the necessary pressure to seal. This leads to immediate leaks, poor cylinder performance, and accelerated wear on both the seal and the bore.
Q: What if the piston seal ring is not replaced when it wears out?
A: Over time, wear causes the seal to lose its shape and sealing ability. The cylinder will start to lose power, drift under load, and eventually fail. Contaminants can also enter the system, damaging the cylinder bore and other internal components.
