Caster wheels are a type of wheel that is mounted on a bearing or axle and is attached to a bracket or frame, allowing it to rotate freely. They are commonly used on furniture, carts, trolleys, and other movable objects to make them easier to move. Caster wheels can swivel, allowing the object to change direction without needing to be lifted.

There are two main types of caster wheels:

1. FIxed Casters: These only move forward and backward and do not swivel, providing stability but limited maneuverability.

2. Swivel Casters: These rotate 360 degrees, providing enhanced mobility and allowing the object to change direction more easily.

Caster wheels are available in various sizes, materials, and load capacities, making them versatile for different applications, whether it's for light furniture or heavy industrial machinery.
