Types of Caster wheels

Caster wheels are crucial for mobility in a variety of applications, from furniture and equipment to industrial and heavy-duty uses. A caster is an assembly that includes a wheel and a mount. Casters support and make it easy to maneuver carts, racks, dollies and other equipment. Casters come in different materials, wheel diameters, tread widths, load ratings and overall heights to give your equipment mobility in many kinds of work environment.

Main Types of Casters

(1) Swivel Casters

Swivel casters rotate 360°, allowing equipment to change direction easily. They’re ideal for tight spaces or applications where frequent turning is needed, such as warehouse carts or hospital beds.

(2) Rigid (Fixed) Casters

Also known as fixed casters, these do not swivel and are used for straight-line movement. They’re usually paired with swivel casters to provide directional control and stability for long-distance movement.

(3) Locking Casters

These casters include a brake system that locks the wheel, the swivel, or both. They keep equipment stationary during loading or maintenance.

(4) Kingpinless Casters

Unlike traditional designs that use a center rivet (kingpin), kingpinless casters feature a raceway without a pin. This design reduces wear and resists shock — perfect for heavy-duty industrial use.

(5) Heavy Duty Casters: 

Designed to support heavier loads, these are often used in industrial applications. 

(6) Polyurethane Casters: 

Known for their durability and smooth rolling, they are suitable for various surfaces.

(7) Specialty Casters

Spring-loaded casters absorb shock and protect fragile loads.

Low-profile casters provide stability for heavy machinery with low clearance.

Medical casters are quiet, smooth, and non-marking for hospital environments.

These types cater to different needs and applications, ensuring optimal mobility and functionality.
