Which side of the foot of the hotel bed is the caster?

There are two directional wheels at the head of the bed.

The universal wheel is the so-called movable caster, and its structure allows 360-degree horizontal rotation. Casters are a general term, including movable casters and fixed casters. Fixed casters have no rotating structure and cannot rotate horizontally but only vertically. These two types of casters are generally used together. For example, the structure of a trolley has two fixed wheels at the front and two movable universal wheels at the back near the push armrest.

The universal wheel refers to a bracket installed on the caster wheel that can rotate 360 ??degrees horizontally under dynamic or static load. According to their different uses, bearings are divided into iron core, aluminum core and plastic core, with sizes ranging from 1 inch to 8 inches. Among them, the iron core and aluminum core are generally heavy-duty load-bearing wheels, which are often equipped with brakes when used.
