Built for 30 to 36 ton machines on general excavation, the 9N4552 uses a balanced profile that loads the bucket evenly from centre to corner. That even loading reduces stress on the corner adapters, which is usually where a bucket set fails first.
The casting is inspected for pocket depth and pin alignment before painting, so a full set installs without one tooth sitting proud.
