4 inch swivel casters
4 inch swivel casters represent a crucial component in material handling and mobility solutions, offering versatile movement capabilities for various equipment and furniture. These precision-engineered wheels feature a mounting plate attached to a swivel bearing assembly, allowing 360-degree rotation for enhanced maneuverability. The 4-inch wheel diameter provides an optimal balance between load capacity and mobility, typically supporting weights between 250-350 pounds per caster. These casters incorporate sealed precision bearings that ensure smooth operation and minimal maintenance requirements. The swivel mechanism utilizes hardened steel ball bearings encased in a durable housing, protecting against debris and ensuring consistent performance. Available in various materials including polyurethane, rubber, and nylon, these casters can be adapted for different environmental conditions and floor surfaces. The mounting plate typically features a four-bolt pattern for secure attachment, while the wheel tread provides excellent floor protection and quiet operation. Many models include additional features such as brake mechanisms, thread guards, and sealed bearings for enhanced functionality and longevity.
