Nefish 4 Inch Casters Wheels, Heavy Duty Casters Set of 4, Durable Castor Wheels with Brake 2000 LBS, High Temperature Casters Glass Filled Nylon Wheels for Workbench, Industrial (-40 degreesF to + 475 degreesF)

• Extreme Heat Resistance - Nefish 4 inch heavy duty casters engineered with 33% glass fiber reinforced, heat stabilized nylon 6/6 material, these heavy duty castors wheels operate reliably in environments up to 475°F (250°C). They won't soften, warp, or degrade, making them the perfect choice for industrial applications like metallurgy, baking, injection molding, and beyond

• Durable & Sturdy - Our 4 inch cart wheels built with a reinforced core and precision double ball bearings, each high temperature industrial caster supports up to 500 lbs. The robust, wear-resistant tread provides excellent floor protection, shock absorption, and long-lasting performance under heavy loads

• Smooth & Quiet Maneuverability - Nefish heavy duty workbench casters features a 360-degree swivel with a smooth-rolling ball raceway for effortless steering and precise control. These heavy duty wheels even in intense heat, movement remains buttery smooth and quiet, reducing operator fatigue and boosting productivity

• Widely Use - These 4 inch industrial casters wheels sealed guard design prevent debris, hot chips, and grease from jamming the wheel or axle. Ideal for a wide range of uses, from industrial oven racks and bakery carts to heat treatment fixtures and manufacturing equipment

• Safety & Quality - Your safety is our priority. Every single high temperature caster wheel undergoes a rigorous final inspection, including load and spin tests, to ensure flawless performance and structural integrity right out of the box. Guaranteed quality and peace of mind

Product Description: Professional-Grade Heat-Resistant Castors – Engineered for Extreme Environments Standard castors fail in high-heat settings, melting, warping, and creating safety hazards. Our industrial castors are scientifically engineered from the ground up to conquer extreme heat, offering unmatched performance, safety, and durability where it matters most. Why Choose Our Heat-Resistant Castors? ► Advanced Thermal Composite Core The wheel is molded from a glass-reinforced composite engineered to withstand continuous exposure to high temperatures without losing its structural integrity. It resists melting, cracking, and chemical corrosion. ► Industrial-Strength Build A reinforced wheel core, reinforced with a thick, heavy-duty tread and supported by a precision steel ball bearing system, provides a superior load capacity of 500 lbs per caster. The heat-treated rivet ensures the assembly stays solid under stress. Ideal Applications: ✔️ Industrial Ovens, Dryers, and Baking Equipment ✔️ Injection Molding and Plastic Processing Machinery ✔️ Food Service Bakery Racks and Proofing Carts ✔️ Metal Fabrication and Heat Treatment Facilities ✔️ Laboratory Equipment and High-Temp Material Handling
