Applicable Scenarios

Suitable for maintenance and overhaul of hydraulic flanges, bearing retainers, transmission supports, heavy guards and motor mounts on XCMG RP705 crawler paver; replacement of deformed or corroded original washers; heavy‑load fastening parts for asphalt paving machinery; thickened flat washers stocked by construction parts suppliers.

▪ Thick body design: Higher bearing capacity and resistance against collapse for high preload applications.
▪ Precise dimension: Inner and outer diameters and thickness follow OEM standards for good fit.
▪ Heat‑treated reinforcement: Uniform hardness and better deformation resistance than ordinary washers.
▪ Anti‑rust finish: Reduces corrosion caused by mud and asphalt dust and extends service life.
▪ Smooth burr‑free edge: Avoids scratches on sealing faces and helps maintain flange tightness.
▪ Good versatility: Matches high‑strength bolts of the same size for convenient installation and stocking.

FAQ

Q: Can a standard flat washer substitute this thickened version?
A: Not recommended for original heavy‑load positions. Ordinary washers are too thin, prone to collapse and cause loose joints and leakage.

Q: Can a lightly rusted washer remain in service?
A: It may be used temporarily after cleaning if free of thinning, pits and cracks. Replace it once dents, cracks or heavy corrosion appear.

Q: What should be noted during installation?
A: Lay the washer flat against the workpiece without tilt, clean contact surfaces before assembly, and tighten flange bolts to specified torque.

Q: What usually causes washer failure?
A: Excessive preload crushing, fatigue deformation under cyclic vibration, local point loading from debris and section loss by corrosion.

Q: Must a spring washer be used together with this flat washer?
A: It depends on assembly requirements. This thick flat washer distributes pressure. If locking is required, use a spring washer or thread locker.
