Basic knowledge of PU caster

PU casters are small wheels that is designed to be mounted to the bottom of a larger object so as to enable the object to be easily moved. Today many home appliances come with casters, as do many types of furniture. Casters are found in many applications, including shopping carts, office chairs, and material handling equipment. Casters operate well on smooth and flat surfaces.

One common type of PU caster is PU swivel caster. A PU swivel caster incorporates a wheel mounted to a fork. An additional swivel joint above the fork enables the wheel to roll in any direction. This makes it possible to easily move the object in any direction without changing its orientation. PU (polyurethane) is an incredibly resilient, flexible, and durable manufactured material that can take the place of paint, cotton, rubber, metal, and wood in thousands of applications across all fields. PU casters are available in various sizes.
