DH Caster 6" Plate Mount Rigid Caster, Thermoplastic, No Brake, 425 lb, C-MHD6TPR

DH Casters Rigid Caster For Heavy Moving

DH Casters rigid caster is a plate mounted caster with a 6 inch gray thermoplastic rubber wheel rated at 425 lb capacity, so it supports substantial loads on platform trucks, flatbed carts, containers, automotive equipment, distribution carts, and warehouse equipment where dependable rolling is required. The rigid design holds a fixed tracking path, which helps keep long or narrow carts running straight in aisles. The wheel has a 2 inch tread width, giving a broad contact patch that helps spread weight over the floor surface. The steel rig uses double-ball heat treated raceways, so the swivel bearing path is engineered for demanding duty where the load stays high through repeated moves. Double-welded legs tie the fork structure together, helping the caster resist twisting when carts hit floor joints or thresholds in everyday material handling.

Key Caster Details That Support Daily Use

• The 3-15/16 inch by 4-1/2 inch plate mount size gives a defined footprint for fastening to cart frames or equipment bases, so the load transfers cleanly into the structure.
• The 425 lb load capacity rating indicates how much weight one caster is designed to carry, which helps plan total cart or equipment capacity when using multiple units on a frame.
• The gray TPR wheel material is described as non-marking, so it is designed to roll without leaving gray streaks on typical hard floors during frequent movement in work areas.
• The 6 inch wheel diameter gives additional height and rolling leverage, which helps the caster roll over small debris or floor joints compared to smaller diameter wheels in similar tasks.
• The nut-and-bolt kingpin construction secures the main swivel joint in service, which matters for shops that expect repeatable performance during frequent direction changes under load.
• Zinc plating on the rig provides a protective coating on the metal surfaces, which helps the caster resist surface corrosion in typical indoor material handling environments over time.

Plate Mount Dimensions And Wheel Fit Details

The plate mount size of 3-15/16 inch by 4-1/2 inch defines the bearing surface between the caster and the cart or equipment frame, so mounting patterns can be laid out to match this footprint for stable support. The rigid configuration means this caster does not swivel, so it is positioned where straight-line tracking is desired on a truck or cart frame. The 6 inch wheel with 2 inch tread width builds a specific ride height, so the caster sets overall equipment elevation when matched with other casters of the same series. The wheel type is specified as gray TPR and non-marking, so it is intended for use where floor appearance matters while moving loads across smooth or finished surfaces.

Using This Rigid Caster In Material Handling

Where This DH Casters Rigid Caster Fits Best

This DH Casters rigid caster is identified for applications on platform trucks, flatbed carts, containers, automotive equipment, distribution carts, and warehouse equipment, so it slots directly into typical shop and warehouse transport setups. The plate mount design suits welded or bolted steel frames where a flat mounting area is available, which is common on fabricated carts and equipment bases in material handling. The rigid layout supports straight-line travel on longer runs, so it is positioned on ends of carts that follow a defined travel path. The 6 inch gray TPR wheel with 2 inch tread width is non-marking, so it is suited to environments that move loads across finished concrete or coated floors while managing floor appearance alongside function.

Details That Help Maintain Consistent Cart Performance

The caster construction is described as designed above industry standards with full double-ball heat treated raceways, which indicates the bearing tracks are built for demanding use where loads stay high and the caster experiences frequent rolling cycles. Double-welded legs tie the fork together, so the wheel support resists spreading under load when carts encounter floor transitions or directional forces. The nut-and-bolt kingpin secures the main joint, so the swivel assembly is structurally locked for applications that require consistent alignment and long-term performance. Zerk fittings for grease are provided to help maintain all bearings, so lubrication can be applied directly into the raceways to support smoother rolling and longer service life during routine maintenance. The 425 lb load capacity per caster defines how the caster share of the overall load is determined, so designers can align cart loading with the number of casters positioned under the deck.

Common Questions About This DH Casters Model

Selecting This Caster For Material Handling Tasks
