18x7-8 forklift rims are specifically designed to fit 18x7-8 forklift tires. The "18" indicates the nominal tire diameter, the "7" is the tire's cross-sectional width, and the "8" indicates the rim diameter in inches. The word "Kalimantan" is likely a distribution area label or a local trade name; the wheel's technical properties are no different from standard forklift rims of that size. These rims are generally constructed of high-strength steel to withstand the heavy loads and lateral pressures of forklift operation. They can be one-piece or split to simplify installation and maintenance of solid or pneumatic tires. The internal rim width and lip design are adjusted to ensure secure and tight adhesion to 18x7-8 tires without movement or slippage. These rims are equipped with bolt holes that match the forklift hub pattern (e.g., 6-hole or 8-hole) for precise installation on the wheel axle. Anti-corrosion coating and surface finishing provide protection against rust and wear in industrial environments, such as humidity, chemical exposure, or metal dust. The primary function of the rim is to integrate the tire with the forklift's wheel system: ensuring a rigid connection between the tire and the axle, distributing the load evenly, and maintaining wheel geometry to ensure the forklift remains stable during straight-line travel, turning, and lifting. This rim is ideal for forklifts equipped with 18x7-8 tires in industrial areas, warehouses, or outdoor areas with imperfect surfaces, ensuring compatibility, safety, and maximum operational life.
