DH Caster 8" Plate Mount Rigid Caster, Polyurethane/Cast Iron, No Brake, 1,900 lb, C-SHD825PUR

Rigid Caster With 8 Inch Poly Cast Wheel

Rigid caster with 8 inch polyurethane cast iron wheel gives a straight-tracking support point for moving heavy equipment where steering is not required. The DH Casters design uses a drop forged heavy duty construction with AISI 1045 hot forged steel, so the rig handles impact in demanding shop or plant environments while still allowing the wheel to roll smoothly under load. A full double ball bearing raceway in the rig provides consistent swivel-free tracking in the rigid frame, which matters when you want predictable paths on assembly lines or fixed conveyor runs. The wheel uses a poly and cast iron construction and is described as non-marking, so it supports heavy loads without leaving marks on typical factory or warehouse floors. With a 1900 lb load capacity, this caster supports cargo containers, factory assembly tables, or heavy machinery in applications that need high static and rolling strength.

Key Caster Details For Heavy Equipment Handling

• The load capacity of 1900 lb allows one caster to carry substantial weight, which helps when sizing casters for cargo containers, factory assembly tables, or heavy machinery where each contact point must safely support heavy loads.
• The 8 inch wheel diameter and 2-1/2 inch tread width create a large contact patch and easier rolling, which is useful when equipment needs to move smoothly over typical hard industrial floors with significant weight on each caster.
• The wheel type is poly and cast iron and is described as non-marking, so it combines a hard core for strength with a tread that reduces floor marks in work areas where surface appearance or housekeeping matters.
• The rigid type holds the wheel in a fixed orientation, which suits straight-line moves and positions equipment where directional changes are handled by separate swivel casters or by the layout itself.
• The zinc plated finish on the rig components provides a protective surface, which matters in environments where humidity, overspray, or minor abrasion could otherwise affect exposed carbon steel.
• Applications listed as cargo containers, factory assembly tables, and heavy machinery show this caster is configured for industrial duty where uptime and repeatable positioning are important in daily workflows.

Plate Mount Construction And Fit Details

This plate mount rigid caster uses a 3/8 inch thick top plate with a plate size of 4-1/2 inch by 6-1/4 inch, so it spreads load across a relatively large footprint on the equipment frame. The mounting type is described as plate, which means the caster is intended to bolt to a flat mounting surface sized for that plate area. The rig legs are specified as 5/16 inch welded legs, providing a welded connection between the top plate and wheel housing that resists flex when the caster hits floor transitions or debris. A nut and bolt kingpin and 3/4 inch axle hold the rig and wheel together, which supports the rated capacity while maintaining alignment over time.

Using This DH Casters Rigid Caster In The Shop

Where This Plate Mounted Caster Performs Best

The DH Casters rigid caster with 8 inch poly and cast iron wheel is listed under plate mounted casters and is suggested for cargo containers, factory assembly tables, and heavy machinery. In these uses, the 1900 lb load capacity per caster supports concentrated weights from steel frames, tooling, or loaded containers. The rigid configuration keeps equipment tracking straight during moves, which suits long-line production cells or moves along fixed aisles. The non-marking wheel description is useful on finished or coated concrete floors where visible marking from repeated moves would be undesirable. With a 4-1/2 inch by 6-1/4 inch plate size and drop forged heavy duty rig construction, this caster fits well on heavy structural bases that present enough flat area for the plate and are built to take concentrated load at each mounting point.

Why The Drop Forged Design Supports Repeatable Results

The rig on this caster is described as a drop forged heavy duty design using AISI 1045 hot forged steel, which provides impact resistance that helps the caster absorb shocks from floor joints and debris without deforming. The full double ball bearing raceway in the rig supports smooth wheel rotation within the rigid housing, which helps reduce rolling resistance when shifting heavy machinery or loaded assembly tables. A nut and bolt kingpin secures the rig structure, supporting consistent geometry under load, which matters when multiple casters must share load evenly to prevent rocking. The 3/4 inch axle ties the poly and cast iron wheel into the rig, letting the 2-1/2 inch tread width carry the rated 1900 lb load without relying on a narrow contact band. Together with the zinc plated finish and welded 5/16 inch legs, these details add up to a caster intended for repeated industrial moves where equipment is relocated, repositioned, or rolled into place many times during its service life.
