In material handling, carts and trucks
need the right caster and wheels to easily move around. Caster and wheels are assemblies that help to make carts movable. Therefore, when you are looking forward to replacing the wheels at the bottom of the cart, you are in reality replacing the entire caster assembly. The caster and wheels are designed into two categories. One, you can opt for swivel casters. In this model, the wheels in the casters are designed to move 360 degrees as the center hub rotates around the main joint. This means that you can easily turn around the corners of the warehouse when carrying heavy materials on a cart. Two, you can also go for the rigid casters. In these models, the caster and wheels are fixed. This means they are suitable for moving loads in warehouses with no corners. However, the wheels for the rigid models can also be designed with bearings
to facilitate easy movement even around the corners.
