DH Casters swivel caster with 4 inch polyurethane / cast iron wheel with brake is a plate mount caster built for medium-duty use where controlled movement and reliable stopping are important on busy floors and work areas. The 4 inch diameter wheel with 2 inch tread width supports a 700 lb load capacity, so one caster handles substantial weight on platform trucks, flatbed carts, containers, automotive equipment, distribution carts and warehouse equipment. The poly / cast iron wheel construction provides a polyurethane tread over a cast iron core, balancing smooth rolling with a solid internal structure for regular shop and warehouse handling. This caster is designed above industry standards and uses full doubleball heat treated raceways, allowing the swivel action to track smoothly under load, which helps reduce pushing effort and steer equipment around tight aisles. The wheel brake locks rotation when engaged, holding equipment in place during loading or unloading cycles.
This plate mount caster uses a plate size of 3-15/16 inches by 4-1/2 inches, giving a defined footprint for aligning with existing patterns on platform trucks, flatbed carts, containers, automotive equipment, distribution carts and warehouse equipment. The plate mount configuration supports a secure attachment point, which helps transfer the 700 lb load capacity from the wheel into the equipment base without concentrating stress in a small area. The swivel type construction allows the caster to rotate under the mounting plate, helping equipment pivot and change direction without lifting or dragging corners. Full doubleball heat treated raceways in the swivel head maintain consistent movement, which supports predictable steering when the cart is pushed or pulled through work areas and around obstructions.
This medium caster with 700 lb load capacity is suited to platform trucks, flatbed carts, containers, automotive equipment, distribution carts and warehouse equipment where repeated rolling and positioning are part of daily routines. The 4 inch wheel diameter and 2 inch tread width keep overall height moderate while still carrying substantial weight, which helps when operators need stable handling without raising deck height excessively. The poly / cast iron wheel type matches polyurethane tread with a cast iron core, providing a running surface intended for regular floor contact and a rigid core that supports the load when moving full carts between work cells. The swivel configuration helps these pieces of equipment navigate aisles, turns, and staging zones, reducing the effort needed to reposition heavy loads in confined warehouse or shop layouts.
The plate size of 3-15/16 inches by 4-1/2 inches establishes a consistent mounting envelope, which supports repeatable placement on trucks, carts, containers and similar equipment when standard plate mount patterns are used in a shop or facility. Double-welded legs on the caster frame securely tie the wheel fork to the mounting section, helping the assembly carry the 700 lb load capacity during rolling and turning without unwanted flex in the yoke. The nut-and-bolt kingpin connects the swivel components, creating a serviceable pivot that works together with the full doubleball heat treated raceways to deliver smooth swivel action under load. Zinc plating on the caster components provides a coated surface that supports normal industrial and warehouse environments where carts and equipment encounter regular handling. Zerk fittings for grease supply a direct point to maintain lubrication in the bearings, helping keep the swivel and wheel motion consistent over time so movement and positioning remain predictable in daily workflows.
