XCMG Spare Parts ANELLO DI 40X50X2 803196662

This is a genuine XCMG replacement seal, cataloged under part number 803196662. We usually refer to it as the anello (ring) based on the dimensions—40mm inner diameter, 50mm outer diameter, and a 2mm thickness. It’s a small but crucial component for keeping your hydraulic system sealed up tight.

Designed specifically for XCMG excavators and loaders, this ring is typically used in rotary distributors or as a static seal in hydraulic block connections . The 40x50x2 sizing is precise; using the wrong thickness here can lead to internal leakage and pressure loss, so it pays to stick with the factory spec.

Constructed from a durable, oil-resistant material, it holds up well against degradation from hydraulic fluids and pressure fluctuations. It’s not just a rubber band—it’s engineered to maintain its shape and sealing force over long service intervals in tough environments.

Installation is straightforward, but as always with seals, make sure the groove is clean and free of burrs before fitting. A small cut or nick during assembly is the quickest way to cause a weep later on.

If you are rebuilding a swing motor or troubleshooting a pilot pressure issue on your XE or LW series machine, check this part number first. It’s inexpensive insurance compared to chasing a hydraulic leak down the road .
