4 inch heavy duty swivel casters
4 inch heavy duty swivel casters represent a crucial component in material handling and mobility solutions, engineered to provide exceptional load-bearing capacity and maneuverability. These robust casters feature a durable steel construction with precision ball bearings that ensure smooth, 360-degree rotation while maintaining stability under heavy loads. The 4 inch wheel diameter offers an optimal balance between ground clearance and load distribution, making it suitable for various industrial applications. The swivel mechanism incorporates a double ball race design that enables fluid movement and reduces steering effort, even when handling substantial weights. These casters typically feature industrial-grade wheel materials such as polyurethane, rubber, or nylon, each offering specific advantages for different operating environments. The mounting plate is reinforced to ensure secure attachment to equipment, while the kingpin design guarantees long-term reliability under continuous use. With weight capacities often exceeding 300 pounds per caster, these units are engineered to meet the demands of industrial, commercial, and institutional applications while maintaining operational efficiency and equipment safety.
