DH Casters swivel caster with 4 inch polyolefin wheel is a plate mount caster built for medium-duty loads up to 800 lb, so a single unit carries substantial weight on platform trucks, flatbed carts, and other material handling equipment. The 4 inch wheel diameter and 2 inch tread width create a compact footprint that still rolls steadily under rated load, which helps keep carts controllable in tight warehouse aisles. The polyolefin heavy plastic wheel construction provides a hard rolling surface, giving consistent movement on smooth industrial floors. The swivel design lets the caster rotate under load, which supports maneuvering equipment around corners and into staging areas. Zinc plating on the caster components provides a protective metallic surface, which helps the hardware maintain its function in typical indoor work environments.
This plate mount swivel caster uses a 3-15/16 inch by 4-1/2 inch mounting plate, so the load transfers over a wide surface on the cart or equipment frame. That plate size supports secure mounting in applications like platform trucks, flatbed carts, and warehouse equipment where mounting area is available. The medium-duty design described as MED DTY CASTER,800LB,4',PL,SW,POLYOLEFIN ties the 800 lb rating, 4 inch wheel diameter, plate mount, and swivel function into a single assembly, which simplifies matching specifications when standardizing across multiple carts or distribution carts. The swivel configuration means this caster can rotate around its vertical axis, allowing equipment to turn and align with racking, docks, or workstations without needing excessive space.
This 4 inch heavy plastic polyolefin wheel caster is specified for platform trucks, flatbed carts, containers, automotive equipment, distribution carts, and warehouse equipment, so it fits directly into common material handling setups. In these environments, an 800 lb load capacity per caster supports dense loads of parts, cartons, or components on a compact wheel assembly, which is useful when overall cart height needs to stay controlled. The wheel diameter of 4 inches keeps ramps and floor transitions manageable while still rolling under substantial weight, supporting steady movement across smooth warehouse floors. The polyolefin wheel type is described as non-marking, so it protects floor finishes in aisles and around automotive equipment while carts are moved repeatedly.
The plate size of 3-15/16 inch by 4-1/2 inch provides a broad interface between the caster and equipment frame, allowing forces from heavy loads to spread across the mounting surface for better structural support. In practice, this helps carts maintain alignment when carrying heavy containers or stacked goods. The swivel wheel type allows the caster to rotate freely under load, which lets operators change direction and angle equipment into tight positions typical around racking, staging areas, and work cells. Within these listed applications, the combination of medium-duty rating, polyolefin wheel, and plate mounting connects directly to the everyday handling of palletized goods, bins, and parts where controlled steering and floor protection are priorities.
The DH Casters swivel caster is described as designed above industry standards, which signals a construction intended to handle its stated 800 lb load capacity in demanding routines. Full doubleball heat treated raceways are specified, meaning the bearing raceways use a double ball arrangement and heat treatment, which supports smoother swivel motion under load and long-term wear resistance during frequent direction changes. Double-welded legs are also indicated, so the fork legs are welded at multiple points, helping the caster frame resist twisting forces from lateral pushes on heavy platform trucks or flatbed carts.
The nut-and-bolt kingpin detail means the swivel section uses a nut and bolt connection at the main pivot point, which allows a robust clamping of the raceways for consistent tracking when the caster is turning under weight. Zerk fittings for grease are specified to help maintain all bearings, so lubrication can be applied directly into the raceways and wheel bearings, supporting smooth rolling and swivel action through repeated use in warehouse, distribution cart, and automotive equipment applications. Zinc plating completes the assembly with a treated exterior surface, which resists corrosion from typical indoor conditions and helps the caster stay functional and presentable over long service intervals.
The C-MHD4HDPS caster has an 800 lb load capacity, so one caster can carry substantial weight on platform trucks, flatbed carts, and similar equipment within that rating.
The caster has a 4 inch diameter wheel with a 2 inch tread width, giving a compact, stable rolling surface for maneuvering loaded carts on smooth floors.
The caster is specified for platform trucks, flatbed carts, containers, automotive equipment, distribution carts, and warehouse equipment, aligning with common material handling tasks.
This is a plate mount caster with a plate size of 3-15/16 inch by 4-1/2 inch, providing a broad mounting surface to attach to carts or equipment frames.
The heavy plastic polyolefin wheel is described as non-marking, so it rolls on industrial floors while helping protect surface finishes during repeated movements.
The swivel caster type allows the wheel to rotate around a vertical axis, enabling carts and equipment to change direction and position precisely in confined aisles.
The DH Casters swivel caster with 4 inch polyolefin wheel unites an 800 lb load capacity, plate mount, and non-marking wheel in one assembly, so platform trucks, flatbed carts, distribution carts, and warehouse equipment can be matched to a clearly defined specification. The 3-15/16 inch by 4-1/2 inch plate size, swivel design, and polyolefin wheel type together support controlled maneuvering under rated loads across smooth industrial floors. For projects built around platform trucks, containers, automotive equipment, or general warehouse handling, selecting this C-MHD4HDPS caster aligns equipment builds with a documented capacity, wheel material, and mounting style.
