Plain bearing bush, manufactured from hardened steel, designed for use in the most heavily loaded joints of the excavator arm. This component is installed in the last bore of the dipper arm and in the bucket linkage, where it plays a critical structural role.
The bush ensures smooth rotational movement of the pin, transfers extremely high loads generated during digging operations, and reduces friction, protecting more expensive components from wear and elongation. Its hardened steel construction provides excellent resistance to abrasion, deformation, and long service life, even under severe working conditions.
A worn plain bush leads to excessive play in working joints, resulting in:
knocking and looseness at the bucket linkage,
reduced digging precision,
accelerated wear of pins and arm bores,
costly structural repairs if ignored.
Regular replacement of the bush helps maintain correct arm geometry and safe machine operation.
