Sleeves that can be disposed on either end of a bushing to improve the wear characteristics and usable lifetime of the bushing is disclosed. During the use of the bushing, such as when a machine including the bushing is operated, the sleeves may be in primary contact with abrasive elements (e.g., other parts of the machine, dirt, rock, etc.) and wear, while the underlying bushing is protected, at least in part, from wear and tear. The sleeves may include a bulk material, such as steel, with a hard coating thereon, such as hard chromium, tungsten carbide, or the like. The hard coating may be formed by any variety of processes, such as electroplating, plasma deposition, thermal deposition, or the like. In some cases, the sleeves, after being worn from use, may be replaced or refurbished to further extend the lifetime of the bushing.
