How much weight do the wheels of mobile storage racks usually carry?

The load-bearing capacity of mobile rack wheels varies depending on a variety of factors, and common wheel load-bearing ranges are as follows:

Lightweight wheels: These wheels are usually used for small, lightweight mobile shelves, and the load-bearing capacity of a single wheel is generally about 5-15 kg. The overall shelf may be suitable for placing some lightweight items, such as a small mobile shelf made of plastic, which is often used to store clothes, documents, trinkets, etc., and the total load may be 20-60 kg. Small plastic mobile storage racks placed in the bedroom, used to store underwear, socks and other small items, using this lightweight wheel can meet the needs.
Medium-sized wheels: A single wheel is generally 15-30 kg. It is often used for medium-sized shelves with a certain weight, and the overall bearing capacity of such shelves may be about 60-150 kg. Like some wooden or metal kitchen mobile shelves, which can place more tableware, kitchenware, and even small appliances, this load-bearing capacity of the wheel will be used. For example, in the kitchen, multi-layer metal mobile shelves are placed to place POTS, condiment bottles and other items, and medium-sized wheels can ensure its stable movement.
Heavy wheels: A single wheel can bear more than 30 kg, and some special heavy wheels can even bear more than 50 kg. Suitable for large, heavy mobile shelf, the overall shelf bearing capacity can be more than 150 kg. For example, large industrial mobile shelves, or shelves used to store large fitness equipment and heavy tools, will be equipped with this heavy wheel to ensure safe movement and long-term use.
However, these data are only the approximate range, the actual load bearing capacity is also related to the material of the wheel (such as rubber, polyurethane, etc.), the structural design of the wheel (single wheel, double wheel, bearing, etc.) and the overall structural stability of the shelf. When purchasing mobile storage racks, it is recommended to check the product manual or consult the merchant to understand the accurate wheel load bearing parameters to ensure that the actual use needs are met.
