4. FAQ

Q: Could you tell me the part number of this piston rod seal?
A: This piston rod seal is part number 326-0766, designed for wheel loader tilt cylinder sealing applications.

Q: What construction machine does seal 326-0766 fit for assembly?
A: Seal 326-0766 is for wheel loader, installed on the tilt hydraulic cylinder piston rod controlling bucket angle.

Q: What raw material is this piston rod seal produced from?
A: It is made of high toughness polyurethane, featuring outstanding extrusion resistance and low friction performance.

Q: What core sealing role does this piston rod seal play in the hydraulic circuit?
A: It maintains internal hydraulic pressure and stops sand and muddy water from entering the cylinder inner cavity.

Q: Where is this piston rod seal arranged inside the cylinder assembly?
A: It is locked in the gland groove of cylinder head and slides against the polished piston rod surface.

Q: How does this seal perform under frequent bucket tilting and impact loading?
A: It can keep stable lip contact force and is not easy to deform under cyclic impact pressure during loading work.

Q: What hydraulic fluid can match this polyurethane piston rod seal?
A: It is compatible with regular anti-wear hydraulic oil widely used on wheel loader hydraulic systems.

Q: What abnormal performance tells us the seal needs replacement?
A: The bucket cannot stay at the fixed tilt angle and oil slowly seeps out from the rod surface under load.

Q: What point should we pay attention to during installation?
A: Check the piston rod surface for burrs first, and use a protective sleeve to prevent scratching the seal lip.
