Pre-bored cast-iron wheels are wheels made from cast iron, a durable and resistant material. They are pre-machined with a bore, i.e. a central hole of a specific diameter, to facilitate mounting on an axle or shaft. This pre-boring makes installation easier and more precise, reducing the need for additional machining during assembly. Pre-bored cast-iron wheels are commonly used in a variety of industrial applications, such as forklifts, handling equipment and machinery where a strong, robust wheel is required.
