DH Caster 5" Plate Mount Rigid Caster, Polyurethane/Cast Iron, No Brake, 900 lb, C-MHD5PUR

DH Casters Rigid Caster For Heavy Loads

DH Casters rigid caster with 5 inch polyurethane / cast iron wheel is built for heavy-duty rolling where controlled straight-line tracking is needed on material handling equipment. The 900 lb load capacity supports demanding service on platform trucks, flatbed carts, containers, automotive equipment, distribution carts and warehouse equipment, so one caster carries substantial weight in multi-caster layouts on these units. The rigid design keeps the wheel fixed in one direction, which stabilizes movement on long runs in aisles or along production lines when operators are pushing or towing loaded carts. The 5 inch wheel diameter and 2 inch tread width establish a compact footprint that balances maneuverability with load support in tight warehouse or shop spaces where floor space is limited but loads remain substantial.

Key Caster Details That Support Daily Use

• The full doubleball heat treated raceways distribute load forces through the caster swivel structure, supporting smooth rolling performance under rated load, which helps equipment move consistently on busy floors.
• Double-welded legs tie the caster yoke together at two weld points, adding rigidity to resist spreading under a 900 lb load rating, which supports stable wheel alignment on loaded carts.
• The nut-and-bolt kingpin construction secures the caster assembly, allowing the structural components to stay clamped together over time under shock and impact typical of material handling applications.
• Zinc plating on the caster components provides a protective surface, which helps the metal resist corrosion in normal warehouse, distribution and shop environments where moisture and dust are present.
• Zerk fittings for grease connect directly to internal bearing areas, allowing lubricant to reach all bearings, which supports sustained rolling smoothness during frequent use in industrial and commercial workflows.

Plate Mounted Caster Dimensions And Fit

This plate mount caster uses a mounting plate sized 3-15/16 inches by 4-1/2 inches, giving a defined bolt pattern footprint for attaching the unit to platform trucks, flatbed carts, containers, automotive equipment, distribution carts and warehouse equipment. The plate mount design creates a broad contact area between the caster and the equipment frame, spreading the 900 lb capacity across the plate for a solid connection on steel or wood frames. The 5 inch wheel diameter and 2 inch tread width combine with the plate footprint to give installers clear dimensional expectations when laying out bolt holes and aligning multiple casters on a cart or truck base.

How This Heavy Caster Performs In Service

Rigid Caster Use On Carts And Equipment

This DH Casters plate mounted caster is classified under builders hardware and plate mounted casters, positioning it for use on platform trucks, flatbed carts, containers, automotive equipment, distribution carts and warehouse equipment where straight tracking is important. The rigid type design keeps the wheel fixed relative to the mounting plate, so carts maintain a predictable path when pushed or towed down aisles or through loading zones. The poly / cast iron wheel construction combines a polyurethane tread with a cast iron core, pairing a hard internal structure with a resilient running surface, which supports carrying the 900 lb rated load while rolling over typical warehouse or shop floors. The wheel diameter of 5 inches raises the load enough to travel over minor floor irregularities while keeping deck height low on carts and trucks. The 2 inch tread width creates a stable contact patch that supports the rated load without requiring excessive floor space, which is useful when arranging multiple casters under compact equipment bases.

Details That Help Maintain Consistent Rolling

The caster is described as designed above industry standards, which ties together features such as full doubleball heat treated raceways, double-welded legs, nut-and-bolt kingpin, zinc plating and zerk fittings for grease to help maintain all bearings in demanding use. The full doubleball heat treated raceways create a hardened, multi-point ball path that supports smoother distribution of forces acting on the wheel, which helps reduce binding when the caster experiences directional changes or shifting loads during movement. Double-welded legs reinforce the fork structure on both sides, so leg deflection under a 900 lb capacity is minimized, helping keep the wheel aligned squarely for consistent tracking. The nut-and-bolt kingpin maintains clamping force on the caster assembly, supporting structural integrity when equipment sees repeated loading, unloading and impacts common in distribution and warehouse operations. Zinc plating adds a protective barrier over the metal surfaces, which supports longer service life where humidity or incidental contact with liquids may occur. Zerk fittings direct grease into bearing paths, helping keep the bearings supplied with lubricant, which supports smooth rolling and reduces resistance as carts travel across the facility during repeated daily cycles.
