Definition & Size: An 18x7-8 wheel rim is a forklift wheel rim with a tire size of 18x7-8, meaning the overall tire diameter is approximately 18 inches, the tire cut-out width is approximately 7 inches, and the rim diameter is 8 inches. This rim is specifically designed to match the tire size and load applied by the forklift. Technical Characteristics: Made of high-carbon steel or other strong metal materials to withstand the heavy loads and lateral pressures of forklift operation. Usually, the wheel is a "split wheel" model, or a rim consisting of several parts (2-piece, 3-piece, etc.), or a solid wheel according to forklift specifications, for easier maintenance and component replacement. The appropriate internal rim width is approximately 4.33 inches (for 18x7-8), to ensure proper and secure tire installation and stable operation. A finishing layer (paint or anti-corrosion coating) to resist rust and corrosion due to humidity or use in harsh industrial environments. Function & Benefits: Supports heavy forklift loads and frequently lifted loads; ensures a secure connection between the tire and rim to prevent slippage or shifting. Provides wheel stability when turning, maneuvering in tight spaces, and lifting loads. The robust construction helps withstand impacts, vibrations, and use on rough or heavily contaminated surfaces. The perfect match between the rim and tire size optimizes tire life and forklift operational efficiency. Ideal Use: This type of rim is suitable for medium- to heavy-duty industrial forklifts, often used in areas such as warehouses, ports, factories, or outdoors with rough surfaces. It is crucial that the rim dimensions and construction match the forklift's specifications for safety, efficiency, and optimal service life.
