7" Steel hub and ball bearing solid rubber tires

This is 7" steel hub and ball bearing solid rubber tire, combining excellent strength (steel hub), rolling performance (bearings), and ground adaptability (rubber tread). It is suitable for scenarios requiring moderate load capacity, good shock absorption, and flexible mobility. Dimensions: diameter 175mm, tire width 55mm, axle hole diameter 16mm. This wheel is typically used for the following purposes: 1. Tool vehicles / hand carts: Widely used on industrial or household hand carts, such as warehouse trolleys, gardening carts, cleaning carts, etc. The steel hub enhances the load-bearing capacity, and the rubber tire can buffer vibrations and provide good grip. 2. Equipment moving wheels: Often used at the bottom of medium-load equipment for flexible movement, such as generators, air compressors, woodworking tools, etc. 3. Robots or mobile platforms: Similar structure tires may also be used in some medium-sized robots or mobile platforms, especially in applications requiring certain buffering and load-bearing capabilities. 4. Outdoor equipment: For example, barbecue grills, portable toolboxes, or field hand-held tools, the rubber material can adapt to uneven ground. Each wheel costs $5, totaling $20. In good condition.
