XB00003296 Loader Bushing for ZW220-6

The original liner part number XB00003296 is a key wear-resistant connector on the Hitachi ZW220-6 wheel loader. It is mainly suitable for ZW220 series models such as ZW220-6 and ZW220-5A, and is usually installed in the shaft holes of moving parts such as the boom, bucket, boom, and oil cylinder, playing a role in reducing friction, protecting the metal shaft body, and buffering vibration. This universal number is its only original factory identification. When ordering, the complete model number, serial number, and installation location information of the equipment must be provided to ensure that the inner diameter, outer diameter, and length dimensions match perfectly.

This product belongs to the category of polymer wear-resistant nylon lining, with core materials of PA6, PA66 or PA1010 polyamide materials. It has the advantages of strong self-lubricating properties, corrosion resistance, low noise, and light weight. Its structure is circular, formed by precision injection molding or machining, with a smooth inner wall to reduce the friction coefficient with the pin shaft, and an interference fit between the outer wall and the mounting hole to ensure fixation. Under the rated load capacity of 5000kg and excavation force of 150kN, ZW220-6 can effectively withstand frequent start stop, impact loads, and dust environments, with a lifespan of 2-3 times that of ordinary copper sleeves.

Regular inspection: Check the bushing for abnormal wear, cracks, or deformation every 250 hours of operation, and monitor for any abnormal noise during equipment operation. Cleaning and lubrication: Clean the shaft hole and pin surface after disassembly, and apply an appropriate amount of lubricating grease (such as lithium based grease) on the inner wall of the liner during installation to reduce initial wear. Replacement timing: When the wear of the inner diameter of the liner exceeds the original size by 1-2mm, severe plastic deformation or cracking occurs, it must be replaced in a timely manner. It is recommended to replace the pin shaft in pairs to ensure the accuracy of the fit. It is recommended to perform preventive replacement every 1500-2000 working hours under heavy load or high dust conditions. The original factory warranty is usually 12 months or 1000 working hours (whichever comes first), and specific policies need to be consulted with authorized dealers.
