The Hamilton 1000 lbs Load Capacity Rigid Caster, model R-EN-4NYB, is an epitome of strength and durability, designed for heavy-duty commercial and industrial applications.
This caster features a Rigid design, providing improved mobility and maneuverability even under heavy loads. The Rigid Caster has a load capacity of 1000 lbs at 3 mph, offering a balance between speed and weight capacity.
The caster comes with a 4-inch diameter Nylast High Performance Cast Nylon Wheel that ensures excellent performance in demanding environments. The wheel has a face width of 2 inches and an overall height of 5.125 inches, providing a sturdy base for load carriage.
To further enhance its performance, the caster is equipped with a 1/2-inch Sealed Precision Ball Bearing. The ball bearings reduce friction in the wheel rotation, leading to smoother operations and longer lifespan.
The Hamilton Rigid Caster comes with a Platinum Powder finish, giving it a sleek and stylish look, while its Charcoal Gray Nylast wheel blends durability with aesthetics.
The caster is kingpinless, making it easier to steer and maneuver. The wheel core and tread material is made from Nylon, ensuring long-lasting performance.
The product comes with a detailed set of dimensions for easy installation, including mounting plate, bolt holes, and mounting bolt dimensions.
If the need arises, the caster can be fitted with a replacement wheel, model W-420-NYB-1/2.
The shipping weight of the caster is 5 lbs, making it easy to transport and install.
This Hamilton R-EN-4NYB 4"x2" Nylast Rigid Sealed Caster – 1000 lb is rated to 1000 lbs per caster. Size a set by dividing the total load by the number of casters, and for uneven floors assume 3 of 4 casters carry the load. Keep continuous-use loads within about 75-80% of the rating.
This caster runs a Nylon wheel with a 2" tread width. Nylon resists chemicals and moisture and carries high loads, which suits washdown and wet environments.
This caster uses a top-plate mount. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.
This is a Rigid caster. Rigid casters track straight for directional stability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
Rated for -20°F to 180°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).
The Nylon wheel performs best on smooth, hard industrial floors. For non-marking or clean-environment needs, ask us about matching tread options.
We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
Application guidance for load margin, wheel materials, and swivel construction. Confirm ratings against your duty cycle, floor, and temperature before final spec.
Start with total system weight (payload + structure + fixtures), divide by casters that actually share the load, and keep continuous working load per caster at or below roughly 75% of catalog capacity (~25% margin). Heavy-duty kingpinless frames are often used on uneven floors, docks, and towed trains where dynamic load transfer is common — do not assume perfect four-caster share. If impact, drop-offs, or shock loading is expected, treat the margin as a floor, not a stretch goal, and confirm capacity at the wheel diameter and tread you select on this PDP. Dynamic and side loads are separate from static catalog ratings; call out towing or AGV duty when you quote so we can sanity-check the configuration.
Stay with polyurethane when floors are relatively smooth, temperatures stay inside the PU service window, and you want floor protection plus rollability. Move to phenolic, glass-filled nylon, or other high-temp / high-hardness options when heat, certain chemicals, or very high point loads push past what standard PU can sustain. Kingpinless construction solves swivel durability under thrust; it does not raise the wheel’s temperature or chemical limit. Use the wheel material and temperature fields on this product (and sibling SKUs) to match the environment — heat duty and side-thrust duty are independent selection axes.
Kingpin swivels concentrate clamping and much of the axial stack through one pin. Towing hitches, AGV corrections, and side scrub introduce lateral and moment loads that work that pin and the race faces harder than hand-pushed carts. Typical early wear modes include kingpin stretch or hole elongation, race brinelling, and increasing swivel play. Kingpinless designs replace that single-pin stack with a machined or forged raceway that carries thrust through the race path, which is why they are the usual spec for powered towing and higher side-load industrial carts. Pair kingpinless swivels with a wheel and bearing package rated for the same duty — the swivel upgrade alone does not fix an undersized tread or bearing.
