DH Caster 5" Plate Mount Rigid Caster, Thermoplastic, No Brake, 350 lb, C-MHD5TPR

Rigid Caster With 5 Inch Thermoplastic Wheel

Rigid caster with 5 inch thermoplastic wheel gives you a straight-tracking wheel setup for carts and equipment that need controlled, predictable movement in busy work areas. This DH Casters rigid caster uses a gray TPR wheel, so it rolls on a thermoplastic rubber tread that is designed to be non-marking, which helps protect finished floors in shops, warehouses, and distribution areas. The caster is built for a 350 lb load capacity, allowing it to support substantial equipment weight on platform trucks, flatbed carts, containers, automotive equipment, distribution carts, and warehouse equipment without overloading a light-duty component. A tread width of 2 inches spreads that load, which improves stability under rolling loads. The caster belongs to the plate mount class, giving you a flat mounting interface for equipment frames that are already set up for plate-mounted casters.

Key Plate Mount Caster Details For Daily Use

• The caster is designed above industry standards, so the construction is aimed at demanding material-handling environments where typical light-duty casters are not suitable.
• Full double-ball heat treated raceways support the swivel action within the rig, helping the caster handle repeated shocks and directional changes over time in warehouse and shop traffic.
• Double-welded legs tie the rig together for added rigidity, which matters when carts and trucks hit floor joints, debris, or dock transitions during normal operation.
• The nut-and-bolt kingpin configuration provides a serviceable connection point in the rig, allowing the structural joint to be maintained over the life of the caster.
• Zinc plating on the rig offers a protective finish against normal environmental exposure, which supports long-term service in indoor industrial and commercial spaces.
• Zerk fittings for grease are built in to feed lubricant to all bearings, which keeps the rolling and swiveling components moving smoothly under load during frequent use.

Plate Mount And Wheel Dimensions For Fit

This plate mounted caster uses a plate size of 3-15/16 inches by 4-1/2 inches, giving you a rectangular footprint that matches common plate patterns on platform trucks and material-handling equipment. With a 5 inch wheel diameter, the caster raises equipment enough to roll over small floor transitions and debris while still keeping deck height manageable for loading and unloading. The 2 inch tread width creates a stable contact patch that helps distribute the 350 lb rated capacity, which supports steady movement when carts are loaded near their working limit. The rigid configuration keeps the wheel fixed in line, so installers typically pair it with swivel casters on the same cart to balance tracking with maneuverability.

Using This DH Casters Rigid Caster In The Field

Where This Plate Mount Caster Is Applied

This DH Casters rigid caster is specified for platform trucks, giving material-handling crews a straight-line wheel at one end of the truck so loads track cleanly down aisles. On flatbed carts, the 5 inch gray TPR wheel supports frequent movement of lumber, sheet goods, or components while keeping floors free from marks. Containers in production areas benefit from the 350 lb load capacity, as a set of casters can carry substantial process parts or finished goods between workstations. Automotive equipment, such as tool carts or parts racks, can use this plate mount design where rigid tracking is preferred near service bays. Distribution carts and warehouse equipment built around the 3-15/16 inch by 4-1/2 inch plate footprint can use this caster to maintain a consistent mounting pattern across fleets, which simplifies replacement and standardization.

Why The Construction Details Matter On The Job

The full double-ball heat treated raceways in the rig help the caster handle impact and turning loads that occur when operators change direction or cross uneven surfaces, which supports smooth operation under regular use. Double-welded legs increase the rigidity of the fork, helping the 5 inch wheel stay aligned under the 350 lb rated load so carts track straight without the legs flexing. The nut-and-bolt kingpin is a serviceable joint, so the structural heart of the rig can be maintained, supporting long-term consistency in how the wheel carries weight. Zinc plating protects the metal components from typical shop moisture and airborne contaminants, which helps the caster keep its structural integrity in indoor industrial environments. Zerk fittings direct grease into all bearings, which reduces rolling resistance and helps the 2 inch wide gray TPR wheel start and stop under load with less strain on operators. The non-marking gray TPR tread matters wherever carts move across finished floors, because it allows heavy loads on platform trucks, flatbed carts, or distribution carts to move without leaving dark streaks that disrupt customer or production areas.

Common Questions About This Rigid Plate Mount Caster

Choose This Caster For Heavy Rolling Equipment

The DH Casters rigid caster with 5 inch gray TPR wheel combines a 350 lb load capacity with plate mount construction sized at 3-15/16 inches by 4-1/2 inches, which suits platform trucks, flatbed carts, containers, automotive equipment, distribution carts, and warehouse equipment. The non-marking gray TPR tread supports floor appearance in finished spaces, while double-welded legs and a nut-and-bolt kingpin back up the structural rig in demanding material-handling environments. Selecting this caster for your next build or replacement keeps wheel size, tread width, and mounting footprint aligned with the needs of heavy rolling equipment in shops and warehouses.
