Casters are wheels that are mounted onto different types of equipment to make them mobile or movable. There different types of casters that are categorized by their degree of rotation and the mounting surface. Casters can either be rigid or swivel casters. Rigid casters are also called fixed casters. They are wheels that are mounted on brackets, and they do have a swivel mechanism that allows the wheel to move independently. Rigid casters can only move in one direction, a straight line, and are, in most cases, used together with pairs of swivel carts on carts to control maneuverability. Swivel casters allow the wheels a rotational capability of 360degrees. Swivel casters are great for simplifying the process of moving loads around corners and in warehouses hallways. Casters mounting surfaces can be stemmed or stemless. Examples of stemless mounting surfaces include mounting plate casters and bolt hole casters
. Many casters also include braking and locking mechanisms that control the mobility of the caster wheels. Looking for the best selection of casters in the market today? Shop at MRO Supply.
